Blazer is stuck at gas station, need carb help...

Sometimes a better way to un-stick a needle valve than beating on the carb is to use a pair of vise grips or pliers to clamp the rubber fuel line hose shut near the carb,and start the engine,or try too,until it runs out of gas--then unclamp the vise grips and start it again--usually the incoming rush of fuel will help dislodge the peice of gunk holding the needle open ..I have driven home a badly flooding carb by using the vise grips to squeeze the fuel line near,y shut,so it cant get enough gas thru it to let it flood--it wont want to run GOOD ,but you may be able to nurse it home that way..

Ah good trick youve taught. Never thought of that.

Nothing worked...I'm not sure what's going on, just going to try and put that 1826 on there. Then take mine off and rebuild it. Something I've never done. Anyone know of a step-by-step instruction I can use? Thank god I know a good friend parting his out. Grabbing 36" h1 tires/wheels off there, a tach, captains chairs and a dash!

I'm wondering if it's my choke. It was set at the richest setting because it was running the best like that. But now I'm thinking it's causing it to flood. Don't know why it hasn't been an issue before. I'm going to adjust to factory mark when I get off work. Just wondering if someone thought that could also cause this before I get to my truck.

Having the choke closed can or will make it not idle and most likely die on you.

With the choke closed and you opening up your throttle plates by giving it gas, you are entering more air into the carb thus leaning out the air/fuel mix being delivered to the motor.

With the motor fully warmed up, you want the choke butterfly to be fully open.

Took the carb off and put the 1826 on there. Good to go. It was definatly letting too much fuel in and the back passenger bowl would slowly flood out the carb.

Your old carb might have a bad float,(a pinhole in one makes it sink)--or the needle valve leaks,was stuck open by a hunk of dirt maybe--Edelbrocks have two of each..the choke being set too rich certainly wouldn't have helped either...glad you got it going,hope this carb works good for you...
