Went riding on it yesterday and a couple of times when I went to start it, it would fire then bog and stall. I thought that's odd but it started up ok, rode it & it was absolutley fine. I go out for my last ride of the day, again I fire her up, bogs, cuts out. I start it again but it's ok, I rode it for about 10 minutes then it starts popping & farting. Bring it in, pull the plug out & the bit that curls over the electrode, sorry I don't know what its called, as nearly broken off. One more lap and I'm sure it would've broken off. The plug gap must've been a good 5mm wide. I'm thinking, shit that was close. Put a new plug in it and would it fire up? Nope. It's got a spark but I'm not sure if it's a great spark. Tried bumping it, putting some fuel in the barrel, disconnecting the stop switch, still won't go. I'm thinking maybe because the plug gap was so big, it's strained the stator or coil???
Just to let you know the engine has been completely renewed, cases, crankshaft, barrel, piston & reed block. Incidentally when we put the engine back in, I spend about 45 minutes trying to get it start, I bump started it & it fired straight up & it hasn't had any problems until yesterday. The engine was rebuilt 8 hours ago.
Sorry for the long post but I'm a bit baffled at the moment.
