[Farmall] Difficult F14

[John Hall]

Looking back at the original post, you said you are definetly losing #4 
followed by an intermittent 1 and 3, correct? I can't see how that could be 
fuel related nor could it be the mag unless it was in the cap, wires or 
plugs. Try this next time it goes to missing--check the fire at the plugs by 
grounding a screwdriver to the frame. You need about 3/16 to 1/4 spark jump. 
If that checks out then spray some WD-40 in the intake with it running and 
see if it helps.

As far as the fuel pump goes I agree with everything that has been said. I 
have had problems with the check valves, trash, and a worn out pushrod.  And 
a busted diaphragm on another tractor with a similair pump. But in all of 
those cases the tractor wouldn't run at all.

One final thought, is the intake manifold tight? You did say the tractor had 
been recently rebuilt didn't you? You may be fighting bad mechanic work from 
the last guy.


Just some thoughts and ramblings.
