318 hard to start when it's hot

Steve,

If your 318 has the B43G Onan with points and condenser, be sure to change out the condenser as the older they get the more likely they are to fail at elevated temperatures.

While not quite as critical on the later P series engines with the electronic ignition, the condenser can still have an effect there as well, so change it for good measure if your engine is a P218.

I agree with Wayne that the PTO is probably set to too large a gap -- should be 0.018 per the manual.

Jim and Steve,

2.5 ohms would be an absolute minimum and would probably indicate that the coil is already deteriorating -- nominal value is 3.5 to 4.7 ohms +/- a bit.
