Smoke when starting! This can\'t be good.
Guys, any advice?
My truck is a 1980, 351 Bronco. A few weeks ago the carb crapped out so I had Ford rebuild it (Holley 600 with a manual choke). It ran pretty good but not perfect, until today.
When I tried to start it, it cranked and cranked but wouldn't catch. So I smelled gas, cursed Ford, and was going to let it sit for a minute, WHEN, I noticed smoke coming out from under the hood/grill (passenger's front).
Well, holy crap, I grab the fire extinguisher, jump out and pop the hood and there is some wisps of smoke coming out from right by the battery (passenger's front). It doesn't seem to be coming from the battery or the selenoid, etc., but it's there and I can't tell where it is coming from. But, that location is where the intake tube for air cleaner meets the grill. So, I'm thinking the carb is smoking and the smoke is coming out there.
Well, once the smoke stops (20 seconds or so) I spray some starting fluid into the intake tube, and it starts but dies when the revs go down, and I struggle with this all the way to my destination. I get there and park it. An hour later I come back, and behold, it fires right up! Vrooom. So I drive it again, park it. Another hour later I go to start it and same thing, no start and smoke. Again, it gets going and runs fine.
I'm ready to go back to Ford and pop a gasket but I need your expert advice first. Can anyone offer any advice on this? I paid $500 for the rebuild [img]images/graemlins/deal.gif[/img] and it's my only vehicle - I need it to run.
