RE: Mac 2815 Weedie Conversion
I was given one of these some 12-14 years ago. parts of the cylinder were broken by the arms of a bucket loader on a tractor.
With the help of the CH Ignition people, I was able to make a 32cc engine with electronic ignition.
it is a great runner 18-8 at 7600 rpm.
The original CH ignition of Wyoming is no longer in business.
