took it out last week and pulled up at a junction,then the revs went haywire and the engine died,started up again fine and been out a couple more times with everything fine but now its playing up again,ive stripped the i/s/c/valve and cleaned it all out,checked and gapped plugs ,checked all multiplugs etc,the 2 main loom plugs look fine but it doesnt seem to idle properly,and when changing up a gear seems to hesitate/misfire sometimes at low revs/boost,i tried holding the revs at 3 thou while it was stood in the garage but it kept fluctuating between 2.5 to 3 any ideas anyone? looks like it could be a trip up to stus if i can trust it to go that far
