Just when I think I have it all figured out, I have a soft seize. This would be the third one with my 65cc metrakit. The first 2 weren't bad, just a tiny smear on the piston. This one wouldn't start up again for 5 minutes, and when I did finally get it going it made a terrible ringing, scraping noise. I had a 2 mile ride home, and I am pretty sure the thing is messed up. I am headed out now to tear it down and inspect the damage.
So my question...can you not run a metrkit at WOT for long periods of time?
I am pretty sure I am jetted right - 80 jet in a 15mm bing with 15mm intake. I have checked 37,982 times for an air leak and never found one. Please tell me what is wrong, so that if it isn't dead, I can avoid killing it in the future!
