Hey Nick< have repaired several of the Traxter MPEM's from that vintage. They die when jumped of the battery is replaces and cross connected for an instant. Blowing the 20 A fuse is a indicated of the internal diode in the MPEM being shorted. I cut open the MPEM case and replace the damaged components then silicone it back together. I have done several of them including my own and they have all worked. Last I looked the MPEM is about $1500 if you can find one. My phone id 770 2512 40 80. Burl

Eddie 63,
Two things make a engine start fuel and spark,
First check to see that you have spark by pulling the plug lead off and putting a plug in the boot then holding the electrode of the plug grounded to the engine. When you crank it you should see a spark.
If it cranks and you see a spark the problem is probably not electrical.
most likely it is fuel system or carb.

On the other hand if it does nothing and it started doing that after the battery went dead and was jumped off the computer (MPEM) may be fried. I can fix the large two plug computers for this and only this problem.

I hope this helps.

McCoy73 .
First make certain that the crankcase is not overfull, if it is to high it may smoke.
My first suspicion would be the valve stem seals. If they smoked before and they did not change them in the top end work that would be the oil route to the cylinder.
My next would be the piston ring gap. Even with new rings if the cylinder is oversize the end gap may be large.
