You dont have to be elaborate about checking the timing. Just take a 10mm
wrench and loosen the nut on the dist. tap the dist a bit in one direction
and retighten. Just remember the starting point. If this preformance gets
worse, tap the dist a bit in the other direction.I have my 10mm  in  my
pocket right now.I would put it back in the tool box, but I always need
it.Gotta put my keys on the wrench to disguise it as a key ring.
