Engine revs at idle – wants to take off when engine is started, before it’s given gas?
|The throttle cable is probably attached too tightly OR has sharp turns, causing loss of “free-play”. Relax turns and loosen cable, route cable w/more gradual turns where attached to handlebar and engine.|
|If unable to relax cable, and the bike still wants to take off when engine is started – adjust throttle cable at carburetor:|
|Check for full throttle:|
|If movement can be detected when pulled – you are not getting full throttle:|
|** IMPERATIVE **|
LOCK NUT MUST BE LOOSENED FIRST – BEFORE ADJUSTING BARREL NUT!!!
|** For those who did not loosen lock nut first – replacement barrel nuts are available at most small engine sales/service dealers. O/D 6mm|
Same size barrel adjusting nut available at many bicycle shops, listed as brake adjusting barrel.
