Last season, had a dramatic power loss and then could not keep sled running ('91 Yam SRV540). Finally, 7 months later, I am trying to fix it. So, I found that one of the head gaskets was burned through. Got new ones ordered, easy to replace. But, I have some questions that I hope someone would not mind helping me out with:
1. What was the cause of this?
2. Is there any possible underlying cause I should be concerned with?
3. The top of the piston has a pit burned in it, not all the way through. I know it should be replaced, but will it run OK or am I risking some other huge problem?
4. Should I, Can I remove the carbon build up on the inside of the head? How?
Sorry for all the probable dumb questions, but I just am not that knowledgeable on 2-cycle engines!
Thanks,
