Pinto carb setup
dogwood - 11/1/09 at 06:10 PM

Hi Guys.

Misplaced my workshop manual AGAIN!!!
I got my SVA in the morning.
Just incase I have prob's with the emissions.
How do I make the engine run leaner?
Couldn't find the mixture screw, when I looked.
Too bl***y dark now, so thought I would ask here.
A pic would help.

Cheers David

Can't help about the carb setting but good look for the morning, don't think you've anything to worry about with a pinto imho if you have you proof of age document.

Cheers

If you look beneath the black diaphragm on the side of the carb there is a plastic tube (white) which is the idle speed adjustor , just below that is a small hole in the flange of the carb , that is the idle mixture screw

Is this it?
Also do you screw it IN or OUT to make the engine run leaner?

screw in to lean the mixture

screw it in fully not tight then screw it out 1.5 turns should be there then
