Hi Gadge
Thanks for the clarification on the rings so guessing the Chrome rings take up the space for a slightly worn bore ,don't think I will do the rings on this engine at the moment as I think the problems mainly in the carb or the linkages. I can get it to start and rev to a nice high rpm but it seems to starve at lower rpm, for now it will run I just have to note how far down I have to put the throttle leaver down before stalling to empty the catcher. I might do a carb overhaul between the 2 engines and see how it goes and if I can get it to a point I'm happy with I might later put new rings in.
When I was first looking at the parts diagram it gave me 2 different options for rings and wasent sure which way to go, If I do eventually do the rings I will check cylinder wear to see if I should go chrome or steel.
If the cylinder is still within spec can U still lightly hone the cast iron sleeve to install normal rings as I know Briggs don't really recommend honing cool bore cylinders either. The cast iron cylinder doesn't seem to be scored and would probably hone out some light scratches it most likely has some oil passing through the ring end gaps.
Also would you be able to confirm valve clearance for the I/C engine?
Thanks.
BS
