carb rebuilding - The 1947 - Present Chevrolet & GMC Truck Message Board Network

reassembly phase of rebuilding my qjet, and i finally ran into a problem. midway thru reassembly, i realized that the fuel discharge ball never came out. upon inspection as to why, its because there is a little ring of rust holding the bastard in!

what on earth do i do to get it out??

*rage'nrat638* · 02-04-2007, 08:26 PM

compressed air

Little hit of wd 40, let it sit and blow it out with air. Keep your eyes on that little ball though, through safety goggles that is.

a needle held with needle nose plyers to scrape the rust away after letting it set overnight with wd40

ohhhhhhhhhhhh yeah, i guess that makes sense. i guess ill take it with me to work tomorrow, and stop off at the goodyear and see if the fellas there might blow it out for me.

well that ball blew right out on the first shot! whew! i was getting a little worried that i was going to be buying a new carb over a tiny rusted metal ball!

hopefully today ill have time to finish the reassembly, and try it out on the truck!

SHE RUNS!!!!

i just put the carb back on, and she fired up on the first crank!!! im astounded that i rebuild a qjet on my first try, but i feel like ive passed a litmus test, and i DO have what it takes to restore a vehicle!

now i just need to figure out how to smooth her out, and ill be able to drive around a bit. i had some trouble with the secondaries intake flaps, but i found a carb shop about 3 miles from my apt, and they had a ton of qjets laying around. they wernt really in the spare parts business, but i talked the guy out of a spring-return for the secondaries, for $5 (i needed it, and i wanted to make sure i left with it!).

i actually had it on and running earlier today, but with the secondaries stuck open. it would fire, but would only run wide open and then die when i let off. now, it starts and almost idles, but then dies. i need to so some reading on what to do with the mixtures, and then im set!
