I almost had it started today, but...
I have been trying to get it to fire using a drill on the magneto side of the crankshaft.
WARNING! DO NOT DO THIS!
I had replaced the stock, cheapo nut with a grade 5. I was turning it over fine, getting spark and it was making the chugging-thugging sound of a 2 stroke. I sprayed a little starting fluid in the plug hole, and occasionally into the carb intake.
Then I started getting the occasional bang. The bangs began to come more frequently, until it sounded like it was wanting to start running.
Then......ZZZZZZZZZZZZZZZZZZ - The sound of the drill spinning without any resistance. The grade 5 nut ate the threads right off the end of the crankshaft!
Back to trying to get it to start manually.
