Rebuilt carb 17057253 Hot issue

(1/2) > >>

bober:
Hi Cliff, I've been running a 17057253 carb and it's been just great except a few instances that I turn it off and it sits for 5- 15 min. . When I start it and take off under normal throttle it seems fine but is I try to get on it ,it will die out and come back . It does this in hotter temps around 80 + . It starts up good and will accelerate fine for the most part . But falls off when near WOT . I'm running a 455/30 over/w/performer and 6x4 heads . I'm guessing to much heat on the carb ? Any suggestions on what to try ? The carb has been rebuilt and is working in all the rest of my driving but this issue . Thanks

Cliff Ruggles:
What size fuel inlet seat are you using in it?

What is the fuel delivery system?....Cliff

bober:
I'm sure it's a short one ,The guy that rebuilt said he liked to use that with a mesh type filter (Marine type?) with an inline filter also, and I have the 3 outlet F/pump mechanical . It's been running so good I thought it was all set until it got hotter weather and it's only under certain conditions it acts up .

bober:
The inline gas filter I installed has at least a couple inch space from anything and room all around for air but if there's something I could use for added insulation I could add it ?

Cliff Ruggles:
The Marine filter is to short unless you are using a short filter housing on that carburetor?

What size fuel inlet seat was installed in the carburetor during the rebuild?

If the kit came from us, it will be the high float N/S assembly.  From a parts store, it will be WAY too small for what you are doing.....Cliff
