autolite 2100 carb question

[SteveC]

ok i decided today to get down to why my 67 is stubling under acceleration.
It stumbales if you slow press on the gas or if you mash it either way from a dead stop 9 out of ten times it will stumble then take off. Acts like it doesnt get enough fuel.

Dad said its likly a carb issue. So on to my question i pulled the carb and when i work the accel pump?? it only squirts gas out towards one venturii but if i turn it really fast or hard it squirts out both. The other carbs i have squirt out of both all the time. is that normal? or should i rebuild my carb again

thanks for the help

mine squirted out of both sides. Sounds like a jet or passage is somewhat plugged.

ok thats kinda what i was thinking. Sigh i will start rebuilding it here later today thanks very much.

Maybe that explains how that truck preforms as well dunno.

something I've done before (some people think i'm nuts) is what we called a $1.50 tune up. get the engine running, rev it up and put your hand over the carb, let it up before it dies and do it again. If it's only a tiny pice of dirt, it will be sucked out when you smother the carb.

I repeat, some people think i'm nuts, but i've never hurt myself.

it's worked for me.

hadnt thought of that... ive done that before and have heard of it.

i ended up pulling it apart and cleaning and replacing a few things when i took the jets out one of them was caked in dirty rust looking stuff i cleaned it out and blasted it out with carb cleaner and compressed air. I then put it back together and filled the bowl with gas and tryied it out and still had the same problem so i just continued working the accel pump and then it started working properly and i put it back on the truck and the 352 accually idles a little better now. Ill have to update this when i take it for a drive, i have to let all the gas evaperate from me being a idiot and forgetting to put the gas line back into the carb.

Thanks for all the help

[unclejtl]

sure, hope it didn't get in your face.

[SteveC]

nope none really got on me just all over the top of the engine as far as the gas goes.

The carb cleaner a little did but that is fairly normal for me
