Problem solved,
Had some time this afternoon to tear off the carbie and have a look see.
First time i have ever seen a float full of gas before on one of these. And it was really full...Qualifies as a boat anchor now...lol... I have heard here on the forums that this is something that does happen though.
Must be a small leak in the float since it took since May to cause me a problem.
Must be a pinhole leak but damned if i could find it, at least visually, would like to though, so i can seal the leak with "seal all" and have it as a spare.
I did have a spare float on hand already though, so i put it in, put everything back together, "O" ring was still good, Used locktite on bolt threads holding carbie to the intake, NO...I didnt use "seal all" since i just didnt see the need for it...lol...DAMIEN
Ps...Running great again as i expected it to. And thanks all for suggestions offered here.
