Dumb question. Does natural gas / propane flow freely into the carb with one of these things or is there some kid of system that allows the generator to adjust the flow as needed? If the engine dies will natural gas just overflow out the air cleaner? it has a regulator with it. one goes on the tank one on the engine. |

Hey guys...sorry I was out laid up with a bad back today. I'll get to everyone's questions tomorrow and petition the owner to extend the deal for anyone that missed out due to my absence.
Thanks and goodnight! |

I have to look at how to mount the regulator to my frame. I'm going to make a drill template for mounting the regulator, and use it to pre-drill the frames on all my generators (even though only a couple of generators will have a conversion kit installed at any given time). In a pinch, this should make it easier to move a conversion kit from one generator to another. |

Motor Snorkel includes a "demand regulator" which is a regulator that is designed with a special membrane that will not allow the gas to flow in the event that there is no vacuum produced from the engine. Therefore if the engine shuts off, the vacuum stops and the demand regulator shuts off. |

Kinda bummed, I'm hearing this people say they ordered the 12th and have shipping notices..... maybe they just didn't send mine but I ordered on the 10th and have heard nothing since :\ Gooodasgone - post your order number and I'll check it out. To my knowledge we shipped everything on Monday but it is possible we missed one. |

US Carburetion: I placed a quick order this morning as I was getting my kid ready using your selection tool. I have a Champion 3500w generator model 46593 with the 196cc engine. Your selection tool did not have the exact model number so I selected the 3500w Champion option and the "all engines" option. It occurred to me just now that this could be a universal kit that is not specific to my generator and may require drilling. Is this kit a "bolt on" for my Champion? Or did I misorder? Hello LTCetme. No, the Motor Snorkel is definitely not a "bolt on" kit. Did you provide us with the engine make/model and generator brand details with your order? If so, then I think you are in excellent hands with our technicians that match every single order to our database of generators/engines. We have a motorsnorkel to fit almost 3000 different engine/generator combos so we almost certainly have one for yours. If not, then we will promptly issue a 100% refund to you. |

Is there a QD available for the short snorkel hose that runs to the mounted regulator? For those of us who either don't want to mount the regulator permanently direct to the generator, or for those who want to be able to remove it when running just gas... I poked around the website but couldn't figure out what size it would need to be.

Should be fairly easy to add in a QD there. You can call US Carb, I'm sure they can help you. |

The engine regulator is a "DEMAND" reg, that allows propane to flow as the 'snorkle' senses a negative pressure or 'vacuum' in the carb intake. And in proportion to said vacuum. There's an adjustment on the input to the demand reg IIRC and its adj to 'fine tune' the installation. For this reason it may be a BAD idea to mount the demand reg remotely from the engine. If it's remounted remotely, depending on distance, then the carb pressure feedback loop has more latency or delay, and the engine is likely to surge. Worth trying tho...

Since this deal is still going on, I'll jump in and ask if you have a tri-fuel kit for the Generac RS7000e with the 420 cc engine. I suspect it's similar to the GP series of generator, but asking you guys seems like the best course of action.

US CARB.
Just got your Motor Snorkel for my Coleman Powermate and it looks like the only way to install the engine regulator is with the primer button always pressed in since my primer button is on the back side. The way I read the instructions that is o.k. correct? In order to seal the fuel inlet to run on gasoline I would just need a screw in brass 3/4" MNPT cap, correct? Thanks for the sale and your help. UPDATE (I cut a small hole in the side plate so I can access the primer bulb. My gen has a full "skirt" on that side). I see most gen's do not so it must not be a question for the majority of them. |

Well it doesn't look like it will work out well for me. I ordered on the 13th and received a unit on the 16th that didn't fit my generator. I took a pic and submitted a support case. Apparently a Motor Snorkel isn't made for my generator so I have to upgrade to the legacy kit for $267. I would not have ordered if I had known the real cost, so now I'm trying to get a 100% refund on what I did purchase (also bought the $44 propane hose). Latest response from support is that shipping isn't refunded AND I have to pay to ship it back?? It appeared you guys had great customer service, but I guess I was wrong.
EDIT: Just got clarification from support that at least I don't have to pay to ship it back now. Just stuck with the original $12.90 shipping cost. EDIT2: I'm not just out $12.90 shipping, they only refunded $120.19 of my $154.30 paid. This is ridiculous. I've sent e-mails, IMs, and called with no resolution yet. Was told yesterday I called too late (4:30pm) and to call back today. |

Was your generator model listed? and did you verify the make/model during the order process? If so, I think you've got a legit gripe about having to pay for the return shipping. If not, and you just ordered the parts without verifying that they would fit your particular generator, then I think they're being generous refunding the incoming charge. |

No, I got conflicting results when using their old site and new site so I went ahead and ordered and put all the pertinent info so they could determine which kit to send me. Its not as big a deal now, they're paying for shipping to send back - at first I was getting stuck with shipping both ways.

A question for those who ordered the propane gas connection kit, how do you connect it to a 20 pound tank? The kit included a male threaded fitting that cannot be used as the connection between the regulator and the tank. I thought I was going to get a plastic nut fitting just like the barbecue hose has for a 20 pound tank.

Unlike the newer QCC (or "OPD") fitting, it inserts INSIDE the tank valve, rather than screwing on around the outside of it. Here's a POL fitting attached to a hose: 
Note that it has left-hand threads - You turn it counter-clockwise to tighten it. |

IIRC, some of the propane valves have an elastomeric 'seat' inside them to help seal against POL fittings with or without the O-ring. They should be inspected from time to time. |

General question regarding these kits. How do I know the generator is operating efficiently with this kit installed? Example. Just because it can run on natural gas doesn't mean that it's not burning a months worth of furnace heating gas running for an afternoon. Obviously that example is an exaggeration but you get what I'm asking. When I'm hooked up to my NG line it's tough to tell if it's consuming way to much until I get the gas bill.
Any concern here? |

Check the U.S. CARB website. Look for the section labeled "CONSUMPTION ". Rule of thumb
Is 10,000 BTU X HORSEPOWER per hour at WOT. NATGAS is billed in THERMS, one therm Being 100,000 BTU. After you wade thru the math you'll find the cost of operating on gasoline to be 4X the price of NATGAS, and propane being 2.5X the price of NATGAS. Of course this will be dependent on your local prices. As long as you've tuned the Regulator per the included instructions, with a Tachometer, your numbers should be in line with your generators output in horsepower. ETA: My local numbers, non-ethanol gasoline $3.00 gal, propane $2.19 gal, NATGAS $.79 THERM. |

Link From what I've read, generators consume 10,000 BTUs per HOUR per HP under load. Residential standby generators come labeled as such. Fuzzy math at best. Each Energy Sector boasts the highest BTU content possible under laboratory conditions. My Yamaha Inverters are much easier to run on Propane and NATGAS without the PITA of storing non-ethanol gasoline, which I've paid as much as $ 4.35 gal in the last year. Although the WISE man will store both. |

From what I've read, generators consume 10,000 BTUs per HOUR per HP under load. Residential standby generators come labeled as such. Fuzzy math at best. Each Energy Sector boasts the highest BTU content possible under laboratory conditions. My Yamaha Inverters are much easier to run on Propane and NATGAS without the PITA of storing non-ethanol gasoline, which I've paid as much as $ 4.35 gal in the last year. Although the WISE man will store both. Quote HistoryQuoted:

Check the U.S. CARB website. Look for the section labeled "CONSUMPTION ". Rule of thumb Is 1000 BTU X HORSEPOWER per hour at WOT. NATGAS is billed in THERMS, one therm Being 100,000 BTU. After you wade thru the math you'll find the cost of operating on gasoline to be 4X the price of NATGAS, and propane being 2.5X the price of NATGAS. Of course this will be dependent on your local prices. As long as you've tuned the Regulator per the included instructions, with a Tachometer, your numbers should be in line with your generators output in horsepower. ETA: My local numbers, non-ethanol gasoline $3.00 gal, propane $2.19 gal, NATGAS $.79 THERM. Since gasoline has about 115,000 BTU's per gallon... [unleaded] And propane has about 90,000 BTU's per gallon... Per hour... Propane has about 3/4 BTU's of gasoline... IIRC. And since propane is about 75% the cost of gasoline at your location... Doesn't that make them closer to equal in cost per HP developed? BTW, according to the first link I pulled up, they are saying one HP is ~= 2540 BTU's per hour...

I guess that's just one more thing to add to the list huh?  It would be nice to have an hour meter too. Sure beats my current logbook technique.

Quote HistoryQuoted: you picked a different setup than I got so I don't know if yours was on Salo le .I got this try this Quote HistoryQuoted: Quoted: Is there a code i need to enter? It been showing $227 for the kit. Is that the sale price? http://www.motorsnorkel.com/high-pressure-propane-gasoline-option-remains-after-conversion-conversion-kit-2765.html you picked a different setup than I got so I don't know if yours was on Salo le .I got this try this |

If you have a Kill-A-Watt meter, it can display AC frequency (Hz) - which is directly related to engine speed on non-inverter generators. If the display shows exactly 60 Hz, the engine on your non-inverter generator is running at exactly 3600 RPM. Also, many digital multimeters (or "DMMs") also have the same frequency measurement function on them. |
