Hi guys, I have an 87 F250 with a 460 engine, it has an Eddlebrock carb on it and I'm having an issue. I don't know a lot about working on cars but I'm learning.
My issue is it takes a while to start it up after sitting a while to get the fuel pumped up to the carb, even after only sitting for 10 minutes it takes a like 10 seconds. is there any fix to this? I checked Eddlebrocks website and found nothing helpful. Its been this way for quite a while. Thanks for any help you can give me. |
| Wasn't an 87 originally fuel injected? Why would you change back to a carb? Float type carbs don't get along with cheap, Alcohol laden fuel. Especially in summer. I'm guessing that fuel is percolating out of float bowl and flooding the engine. You might be getting some vapor locking also. |
1986 was a bastard year, and I think 1987 was too. In 1986 the 302 trucks got EFI but the 351W motored trucks still had Holley carbs (I still have the one that my father bought new). I don't think Ford changed the 460 trucks to EFI for a couple years, so it hasn't been converted. As for the carb problem OP, my suggestion is to take that Edelbrock carb and throw it as far as you possibly can. Maybe even use it for target practice or throw it on eBay and let some other poor guy deal with it but for God's sake, put a standard Holley back on there. I'm sure I'll catch a bunch of shit for this post but what the hell, I've only been doing this for a living for the last 20 years. 
I'm sure that the Edelbrock carb on your truck can be made to work OK but I've had much better results over the years from Holley carbs. Yeah, they need some loving every 6 months or so, and the float bowl gaskets leak like a bitch, but my poor old 86 sits for months on end without being started and I can aim the key at it and the damn thing will start. Every single time. Even that time when it broke the #4 rod, windowed the block, broke the cam and dumped 6 quarts of oil on the road. I drove it about two miles to the house (on six cylinders) and the next day when the wrecker driver dropped it off at my shop, that tough old bastard started right up and limped itself into the shop under it's own power.

Your carb isn't leaking unless you have a cracked body from over tightening. They have no gaskets below the fuel level. I really like them for street carbs, they don't run crazy rich all the time like a Holley. How is the rest of your tune up? Are the plugs and wires crazy old? What model of edelbrock do you have, electric choke? Is it wired correctly? You may be experiencing vapor lock, how is your fuel line routed? You might try insulating it. |
