Went for drive today, about 2 hours long, on the way home decelerating hard down slip road, the engine stopped, strong smell of gas. On openning bonnet, petrol dripping out what appeared to be secondary throttle shaft area. ou: Anyone else had this problem, had a tow home
We're thinking along the same lines Andy. The secondaries must of gotten drowned with gas for it to leak out the throttle shafts like that
Would a sticking float stop the engine? It was really sudden. I think my holley is the 4160? the one with metering block on secondaries. If this is the problem how do you stop it happenning again? I must confess my sins,ray: it is sitting on a small block Che*y. In England you have to make sacrifices to keep your Buick on the road
If the engine flooded, it would certainly die out. My suggestion would be to take the carb apart and check for any debris in the needle and seat. Clean it up and blow everything dry with some compressed air. Re-assemble everything and start her up. Make sure to check and adjust the floats properly. Do you run a fuel filter?
I have a fram filter near fuel cell and one of those little glass ones before the carb, I noticed some debri in the glass one today . I have just finished building the car, so your theory sounds good.
A single grain of sand was all it took to bring my engine to a halt, once the float had pinned it in the valve seat it I didnt have a chance :eek2: Thanks guys for your words of wisdom :beer
good to hear :TU: I love when people post that it's fixed and we guessed right. I like to know what was wrong either way. I wish I'd have mentioned yesterday how easy it is to remove the needle and seat. Yes Jason we were thinking the exact same thing. You posted while I was typing. Ya beat me!! lol. It's funny, one day last year I decided to take a video of my car starting up and running. I turn on the camera, walk over to the car, fire it up and while it's warming up it starts running weird and won't clear out. Knowing something was wrong I turned the camera off and pulled the air cleaner. Sure enough it was the front needle and seat. There was a small metal shaving caught in there. So, it's captured on video. Someday, when I get a faster internet connection I'll post it on youtube. You can hear the engine change its tune the moment the needle hangs open.
