My first blown motor
I put total loss on this ski a few weeks ago and couldn't get it to run right. The spark didn't seem right. No throttle response. Would go dead and not start for a while. Checked compression and changed coils a few times. Then it suddenly wouldn't start at all. Timing light showed no spark or off time sparks. Figured it was a bad brain. Maybe it was, I don't know.
Switched it out to a known working stock ignition today and it still won't start. Spark is there with a timing light. Spark....check. Gas via primer.....check. Compression?.....no, I just checked it last weekend......WTF! 25psi in rear cylinder. WTF!?
I have a black cloud over my head this year.
Question is was it the total loss that caused it or was it coming anyway?
Likely problems are....?...bad rings? hole in piston?
