[AT] bad condensor?

[John Hall]

This saw is rather old as it uses points.

Whatever it is seems to be time sensitive. I can't run the saw with the fuel 
cap loose since is screws in the side. I could try looseneing it once the 
problem arises to see if it helps but since I have replaced the fuel tank 
vent then I doubt that is it.

I'll try the coil swap soon and see what results that produces. Funny thing 
is the saw starts missing and if you let off the throttle it will normally 
sit and idle and then rev back up, but not for long. Once it cools its ready 
to go again.
