Due to health problems I have not been able to drive my Corvettes since I stored them for the winter in November 2006...so none of my C3's have even been started in 2007 or 2008.... BUMMER....
Anyhow I am "almost" ready to drive again.. started driving my sons automatic Grand Cherokee 3 weeks ago and have not wrecked the darn thing yet because it has a BIG brake pedel that I can not miss with my foot... hopfully I may have all the feeling in my feet back in a month or so then I can drive a car with 3 pedels on the floor...
Anyway... 4 of teh cars started right up and ran fine about month ago... but my 72 smoked, bucked, shaked rattled and rolled stumbled etc.. I had a very hard time keeping it running... never could get it to idle as the garage was kind of "smokey" and I thought it best to get out of dodge and breath some fresh air...
I am a stuborn old fart and I got top get out there and figure this thing out...My initial thoughts was that the Float in the carb may be stuck.. BUT agian it has been many moons since I have had a similar problem with an engine ....
Anyone out there who can give me some things to look at besides the carb ..or before I even mess with the carb...
Rather depressing the last 2 years not being able to drive the cars and I hopefully I can still get them out for a few short drives this year ...

Bob,
Just a guess, Is it possible you have that blasted Ethanol in your fuel/ tank.. I know some folks that have lot's of trouble leaving it sit for long period of time.. screwing up carbs etc...

Bob, you have a way with words (stuborn old fart). Sorry that things have been bad for the past years. Now I would try some of the old carburator/injector cleaner; http://www.pennzoil-quakerstate.com/products/gumout.htm I would also change out the plugs, which are probably fouled. I hope things work out for you. Take care, Larry

Bob, I have to ask: Every one of your cars has a satilite reciever dish? So how is the reception in the vettes? I'm just kidding.

I'm wondering if the gas went bad.
Did you use a fuel stabilizer while they sat?
I'm glad to hear you're getting better!

Glad to hear you're starting to be able to get around again, Bob!
I'd have to think it is a fuel issue, too. Bad fuel. that is.
However, it's possible that the float on the '72 got stuck while sitting. They'll do that sometimes, as the floats are made of a resin-type material. Once they soak up enough fuel, AND sit for long periods, they swell up, which causes them to stick. I had this exact issue on the '74 before I ever bought it(I built the carb for the guy I bought it from). The float was so swelled up I had to pry it out with a screwdriver. The car would start and run....barely.
I think yer gonna wind up pulling the carb...

Thanks guys....
Since I have to push the car outside and my legs ain't that good yet I'm getting help over on Thursday .. Hoping its as simple as the float...But I do intend to run some "gum out" or whatever that stuff was vcalled that I last used in the 1950's... I do have a spare carb in the garage ..but dumb me never tagged it so I have no idea now if it was working when I pulled it or even why I pulled it and I know the spare is a Quadrajet the 72 is running a Holley ..figures !
Will let you guys...know how I make out...
Thanks again
Bob
