Bought this blaster a month ago for 500 bucks because it had no spark. Tors delete was done incorrectly so I rewired it and got spark. Got it to run for a few seconds off starting fluid and engine sounded good and healthy. Cleaned the carb put it back on the bike and went to go and start it. When I kicked the bike over it had a loud squeak, sounded like a mouse was in my engine. I don’t know if it’s an air leak or if it’s bad crank bearings.
Other things worth noting:
I found that the crank case was cracked right where the kickstarter shaft does. I had it tig welded.
Will attach a video
Video of the squeak , I’m completely clueless on where this could be coming from. Any help will be greatly appreciated.
