Subject: [AT] Firing on two instead of four


Hey,
    I was playing a short time today with my Case SC which I got at the end 
of the summer.  It had sat for a few years.  I couldn't get it to fire at 
first when I picked it up in August, but just put in four new plugs and it 
ran great.
    Anyway, lately it has been running on just two cylinders.  So I took the

plugs out and cleaned them and laid each individually down and turned the 
engine over.  Had strong spark in all four.  But still only running on two. 
Had a new spark plug wire which I tried and still the two would not fire 
when tractor was running.  Even switched the good wires to the bad plugs and

vice-versa....same results.
    My last test was I pulled the wire to the plugs which were not firing 
off the distributor cap while the tractor was runnining.  As I held it about

1/2 inch from the distibutor, it arced and fired.  Did the same with the 
other wire which wasn't firing.  Cleaned the contacts and reconnected the 
wires.  Same old thing.
    Suggestions???  Is the distributor bad?  Tried to look close for cracks 
or wear.  Looking for the next step.

    Thanks.  I don't contribute much anymore, but still lurk.
