Hi, As the title says having a problem with stuck rings. Running a GX200 stock,governor removed,advance timing key(6degree) header. Motor turns about 5500 running 90 octane non ethanol gas. Motor will run great for a while and then loose power puff a little and die. This has happen with 2 different motors and numerous times. Pull them apart and every time top compression ring is stuck in ring groove. I have replaced pistons,replaced rings same thing keeps happening. This last time we only got 2 races out of it. The engine setup is the same thing everyone else is running but we seem to be only one with this problem. Looking for any ideas,advice it’s starting to get old but I will say my 14 year old son is getting pretty good at pooping them apart and putting back together. Have tried different oils and it has happen with every brand( Amsoil Briggs 4T, Royal Purple, Mobil 1)
Thanks
Thanks
