[AJD] Backfire

[Gary Epps]

I had just adjusted the valves, actually one using the technique in the 
operators manual.  Turning the flywheel until just before the left 
exhaust valve opened and then checking to see that all tappets had play 
in them.  One was considerably tighter than the rest, so I backed it off 
to where it felt like the others. The engine was cold and I reasoned 
that the clearance would be tighter with the engine warm. I guess I had 
better readjust it an warm it up tomorrow and then adjust them.  The 
valve adjustment is the only thing that would be different from when it 
last ran.  I guess the procedure would be 1 readjust, 2 warm it up and 
check all four, 3 check the mag timing if I am still getting excessive 
flame out of the exhaust.  Thanks Greg.
