I've tried ! really I have ... do you use the SEARCH only in the zones where it might be ? Or does the search header just search from whatever forum you're in ? Augi was going to drill out his main jet back in March I think ... Somebody else jetted 'Rusty" and promised to start a new thread .... then it all just ended .... "jet" "main jet" "drilling out the jet" "jetting the carb" "enlarging the jet" were all tried and I redid those searches after going to each of the forum zones ... How in blue thunder does search work ? It was no better in advanced search where it came up with no results at all and I'd just finished reading 6 posts on the main jet ! Before anyone leads me to "Exhaust Performance" ... Been there /done that ...
