Tim have you had a read of the CPS tech articles especially part 2 and 24,

I have no experience with the rotax point ignition engines mine are Ducati but keep reading about the dampening box giving odd faults,

You have not said weather you have done any checks of the ignition side of your engine...but as the other guys have said...contact breaker points do need lots of care,

If you have not read the article it will be well worth while....I have used them lots over the years I have run my 503....the link is below.
