Ignition coil tech question


Recommended Posts

Hi, anyone a guru with coils?

I've a HE r120. The resistance in the coil between cap and ground is 7.87k ohms is this too high for this coil? 

I read that others like top 80 etc should be max 5k.

My motor can be sputtery when running but main issue is hot starting, won't start until engine has cooled.

I had a Ros 125 that would not start when hot. I was told the carb was hot and vaporizing fuel. I put in a nylon spacer between engine and carb, this helped a bit
