In Reply to: What's causing the sputtering - help please posted by DG on April 07, 1998 at 21:00:06:
I know you say the plugs are new, however, new still MAY be defective. I'd pull them and test 'em (UNDER PRESSURE-95lbs. or so).
--not firing right under load (high compression).
Just a thought. Good luck.
: I have a Farmall B that sputters and pops slighty. It is
: most noticeable at mid/high speed (idles perfect). Here is what I checked
: and think are working ok. New points,plugs,distributor cap,
: rotor,plug wires. Checked timing. I tried 2 different clean carbs.
: Checked the compression - all 4 cylinders read 95 psi. Checked for vacuum
: leaks on the intake from carb to cylinders. Fresh Gas
: It runs great other than this variable pop/miss that is driving me
: crazy. My next guess is carbon build up in the heads or intake manifold.
: Any suggestions would be greatly appreciated.
: Thanks, DG
