Subject: Re: Problem with Coil ignition conversion
Hi Roger,
Could be a problem on the low tension side. Poor connection, corrosion etc. Specifically in the ignition circuit, as if the engine is spinning over as fast as it normally does, one must presume that the heavy current starter circuit terminals are sound. If starter speed is slower, check those terminals as well. Try running an earth connection from the magneto to the engine block.
Good luck!
