Another piston eaten up
Just got back from having motor ported wit about 1 hour on it since then and then this happens. This is not anything to do with the port just happened that way. Motor was running real good and after 30 or so minutes on the water was running about 6500 and just cut out. Restarted and was able to get back to shore. Any one have a case and piston resonable?
The fuel setting were at 6,9,6.5 ,6.
I know pictures. I can figure out how to get them up.

John, That looks lean as hell. looks like you are running an R&D powershot? not sure how to set these but was advised to stay away if possible as they are a bitch to get right and eat pistons.
I have 1300 pistons but no non PV ported cylinders.

I bet the ring spun and caught the exhaust port

That what happened last time same #2 cylinder. How can you stop that? This is getting expensive.
Bill it is a Riva controller.
Jim What should the pots be set to to stop that?
Thanks for looking guys.
Bill I can get them ported again I think I know a couple of people that can do it.
Hope to find a set quickly to get them back for MB.

John is it possible your fuel controller is bad?
