been working on a '91 mustang mini stock, trouble is it has burnt out 2 boxes. I put a different one on and it ran for once, had to keep feathering it to run, then I shut it off after like 5 min, it sounded like it fought timing for a min. then backfired now it just turns over, and the box is getting warm again, is there something screwball I'm missing here?
specs:
91 mustang lx 4cyl hatch back *has a 85 svo nose and hood*
oval port head with 2bbl intake and motorcraft carb *rules said stock carb*
Is it grounded properly?
been wondering that now sitting here probably need to run a bigger gauge ground wire, btw the needing to feather the gas; could the carb be too much, it came off a 2bbl 351m from a 79 bronco
in the stang or the truck it came from? the engine is a stock '91 2.3 4cyl, with like a stock '79 mustang/pinto head
Think about that for a second. Youre using a carb for a stock 5.8 liter engine on a stock 2.3 liter engine.
You are probly flooding it out also,I used a 360 carb on one i had built but it was near 13.1.
it is still a sub 350cfm carb
Are you using Motorcraft boxes? I couldn't keep a Autozone/Advance Auto box in my car for more than a couple of weeks. Put a dingy old motorcraft box in that I got from a junkyard to get me home and I never had a problem with it since.
yeah the track i'm at says it must be a stock rebuild...lmao show me one stock car, go ahead i dare you. i'm gonna rebuild the carb ect this winter, jet it down a lil, it's not terrible, just a lil off when you first hit it,high rpms it loves, found out the week i was going down that there's no race and the week after I'm going to the englishtown swap meet * was alot of tbird/cougar and ford in general stuff in april*...so next year it'll give me some time mess with the suspension.
