The impression I get, is that for someone who knows more about engines and LIKES to "tinker" with them.. they are great...

For someone like me who preffers less work load and, due to work, has little time to spare on maintenece, brands like OS are more suitable....
Maybe thats what you pay for when you pay less.... rather than a "better engine"

Anywho, I have it all plumbed in again, and had a wee test run at home, got the GF to man the throttle and I shook the hell out of this thing, turned it every way I could the lot...
after setting the needle valve... no hickups, no stutters, nothing.

Tomorrow i'll take it to the club and see what I get out of it....
