I thought Ken's post from 12-1 (hesitation ...) was just what I was lookin for, but nope. Drove home the other night and thought I was running out of gas (1/2 tank). For some reason I pulled out the choke, it came back but with higher RPMs. Pushed the choke in and it died.
Got any thoughts?
Thanks ahead of time, jeff | | | | | Joined: Dec 2001 Posts: 1,745 Member | | Member Joined: Dec 2001 Posts: 1,745 | Closing off the top of the carb (choke) does increase vacuum. I would check for vacuum leaks or fuel delivery problems, clogged fuel filter, fuel pump etc.

Closing the choke helps "suck" more fuel through the main circuit (it is actually atmospheric pressure that pushes the fuel to an area of lower pressure). | | | | | Joined: Jun 2000 Posts: 2,773 'Bolter | | 'Bolter Joined: Jun 2000 Posts: 2,773 | Since it's a leakmeister Rochester, check the throttle body shaft for wear, too. Major source for vacuum leaks.

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

As usual, the responses are "always" quality. And, in checking all of the above, I've ordered a rebuild kit from NAPA. Can't hurt.
I should have this solved over the weekend.
Thank you all ahead of time, jeff
