Got the MCD started after a new spark plug and several pull, but its not seeming to hold idle ive put the carb back to factory settings and messed around with the big screw but it either revs to much or to less that it turns off. what would this be as i am having problem after problem just wanna take it out.
 
when adjusting you want to turn only a small amount as pos maybe its got a air leak somwere try spraying wd40 near inlet all around ect it will pick up or die but you will know its got or not got a leak if it does nowt then its not that and maybe dirt in the carb try taking out the adjustment needles one at a time clean them put back at factory its all trial and error mate is there movement on the throttle shaft they do waer and leak in air but i cant see it being a air filter problem unless its so filthy it cant get air

Mate nice1 for the advice ill try this as most off your advise is right. :w00t:

Do you have a contract number witch i could call you on so you could explain it better if you don't mind. as i don't fully understand :mad:
 
you could also try taking the carb off you fg mt and try that on the mcd if its working on the fg engine it should be fine on the mcd it may be the carb
