I've been looking through the posts but can't see anyone with the same problemes i'm having.
Was out on the bike on Sunday and it started to bog down and not rev untill it eventually cut out and wouldn't start again. (luckily i was only about 50 yds from the garage!
Thought it was dirt in the carb so i took it off had a look, couldn't see anything in the bowl, put it back on, started the bike on choke and it ran for about 30 secs then the revs started to rise and it cut out and wouldn't start again.
I then took the carb off the bike and stripped it completely, sprayed carb cleaner everywhere and assembled it all together again, put it back on the bike and checked the slide was in the correct place, wasn't stuck open, the throttle cable wasn't getting snagged anywhere
and started it again.
It did the same thing again, started after the fourth kick, just the usual slightly higher than idle revs on choke, ran for about 40 secs then the revs started to rise and then it just bogged down and cut out. i never once touched the throttle.
The air filter is nice and clean as i did it a couple of weeks ago, it has a new spark plug (even tried the old one back in) but only seems to start if the carb has been emptied of fuel.
I'm at a complete loss here. HELP!
