Update: Compression is right around 150psi. So that seems fine. Also have new plug and a rebuilt carb.
Update: So, I have rebuilt the carb and replaced the plug but no start. I do believe its pulling fuel because its pretty easy to pull and wasn't before (it sat for a few years). The lubrication form the mix got it moving well enough. Thing is it will only 'run' after pouring some fuel directly into it. It seems like the carb is not stock to the saw but does fit all the controls. Nothing Ive seen says the Walbro WJ27 is stock to it. So..... with that.. I dont know if it has reeds in it or not. Spec sheet says its supposed to have a 4 sided pyramid setup. So I got a free vintage Homelite saw (no brake) and need some ID help. I think its a Super XL-925 but not 100% sure. There is no ID tag on the saw that I can find. So here is what I really have to go off of. A worn clutch cover and its model number. Model number doesnt exactly match what pops up as clutch covers for sale but XL-925 covers do with ever so slightly different PN's. Idea is to restore it to working condition  I am certain it isnt an XP-1020 or similar 100cc saw.  Attached File Attached File |

Careful with the fuel on that. I had one identical and it ran on 32:1, I believe.

I don't know what it is, but the Homelite color is the exact same as chevy engine paint. Just in case you were thinking about going there. :) I had a Homelite 20" mower for over 30 years. B&S 3.5 HP aluminum-deck bagger that manicured a yard like no other. Everything started to go downhill about the time they discontinued the correct blade. I only used it regularly '90 to '94 when we moved to a bigger place and I needed a 21" self-propelled mower with the power to mulch. I still kept the Homelite but lent it out to relatives, who just about destroyed it, so every fall I would fix it all up again. This went on for years until everybody was finally done with it, and it had started to have a little rattle in the connecting rod. That's when I took it apart and put it in the trash can. It was just done, but that engine never used a drop of oil.

Take the carb apart and see if the “tower” in the middle is gunked up. That is where the problem usually is, especially if it tries to run when you manually add fuel.

Just get a new carb for it off Amazon, should be less that $20. That's the way I've fixed nearly all my 2 stroke engines that were hard starting or wouldn't stay running, it's never failed.

Hell yeah! Built in a time when men where men, a saw was a saw and the only safety feature on the thing was "don't be a dumbass".
My SXLAO  Attached File Attached FileShe's got a new cylinder and piston, rebuilt carb, ditched the points and condenser for a solid state chip, new recoil spring and 1/8" amsteel blue abrasion resistant line for the pull cord. A full chisel Oregon professional chain and some 32:1 mix and this thing EATS. |

I'm currently working on bringing a Poulan 306 back to life. I just took the carb apart today and dropped the diaphragms in some tranny oil to make them less crispy. I'll let you know after they've soaked a few days. If the more pliable diaphragms pump and meter fuel better and allow it to run, I'll buy a replacement kit. I also found some waxy build-up in the fuel line, so I replaced the small diameter line and cleaned out the large diameter line. The saw I have is low on compression, so this is more of a quest than an expectation of having a viable saw. I don't think I will use a saw with no brake enough to justify rebuilding the piston and cylinder.
As a side benefit this saw is very similar to the 245 used by Leatherface in the Texas Chainsaw Massacre: (not my saw, representative image)  |

Compression check, vacuum/pressure check on the crankcase are all good ideas...
However, if it runs pouring mix in the carb throat, it should have enough compression to run if the carb is close. Odds are either the carb is really stopped up OR it's just not getting enough fuel. So potentially the carb isn't correct for the saw OR isn't adjusted properly. If you get it to run on the carb but it won't idle for shit....it's definitely time for a crankcase pressure/vacuum test. |

I guess its the Homelite season of no starts, except my three start but won't stay running. One I just had a new carb put on mid last year and it will start and run and it will rev up for 30 seconds then quit. I use non ethanol gas and they don't sit for long periods of time. I put all fresh gas and some sea foam in the tanks and hoping that the short time they run, the sea foam will loosen any gunk. When I get a chance I'll do carbs I guess.
Edit: This morning the Super 240 Classic started and ran. Lots of smoke from the sea foam additive but after a couple minutes it lessened as lot. One other started and quit, the other one just laughed at me. At least 1 have the one I wanted running, is. |

Are your jets adjusted to an appropriate starting point?
Should be close to 1 1/2 turns out on both. ETA pretty sure those were reed valve type so you should have the pyramid with the valves between the carb and the cylinder. |

I think it may be a slightly bent reed. Its ever so slight but when put against a machinist square it shows light.

Reeds don't always sit in 100% contact with the sealing surface. Outboards generally have a spec of about .020" that they can be off the sealing surface. I'd imagine all 2-strokes are about the same. |

Only run ethanol free gas in it with echo 2 cycle mix. 32:1 mix. Better to have a thicker mix than too thin

Learn how to adjust the carb needles. Usually a 1/2 turn one way or the other on the low speed jet will get it starting like a champ.

So I opened up the carb again. Looks like I had the wrong circuit flapper sheet thing (dont know what its called..lol) and it had an extra hole so.. tiny fuel leak from that. I flipped the slightly bent reed and reinstalled. Then the pull cord decided to break

Hopefully the reed doesn't break. You aren't really supposed to flip them
over and re-use. Broken reeds will absolutely destroy the engine..   I think these were over-revved and not flipped, but they made a big expensive mess out of a Merc V-6 outboard. |

Rebuilds are fun. Not necessarily economically sensible, but still fun.
If isn't for serious use, take a look at the new electrics. The manufacturers are doing a good job with some of them, |

May need to do a vacuum and pressure check on the engine. Air leaks will kill a two stroke. Make a block off plate for the exhaust and one in place of the carb. Get a brake line tester from the auto parts store that can pull a vacuum and pressurize. Something that old generally needs crank seals to run right. Also remove and check your flywheel and make sure the key isn't sheared on it getting it out of time if it is cast into the flywheel. As mentioned earlier check for exhaust blockages. I have also seen the porcelain on the sparkplug break and cover the electrode so check that as well. If it has reed valves make sure a saw chip is not hanging one open.
