‘66 carb id and question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

hevymetl · 04-06-2018, 08:54 AM

‘66 long bed c10. In-line 6, assuming original. Truck runs good but after sitting all winter, I had to put a little fuel down carb to get her to fire. When I did this, I noticed a little seepage from shaft pivot(?). I would assume that means there’s air leaking as well? Also would like to do clean up and rebuild on carb. What carb should be on there? I have no reason to believe it’s not original equipment.

Thanks, John.

Fuel will run out the shaft when you dump fuel down it. Does not mean there is a problem.

Throttle shafts will leak a little bit, that's normal. If you can wiggle the thing back and forth and actually see that the shaft moves laterally, that's a vacuum leak which may cause some funky idle issues.
They can be repaired but it takes special tools.
