200 running rough

[rog60]

engine only running with choke on is a good sign of main jet blocked.............in fact take carb apart thoroughly clean in petrol/parafin, blow all jets through with air line and re-assemble making sure that all parts are scrupulously clean on re-assembly.....................


P.S. also ensure that atomiser has not unscrewed..........happened to me once.

[lifes a drag]

do you know anybody else with the same spec scoot as yours so you could borrow there carb to see how yours runs then ?

my jetex too had a 'boggy' problem,found a lump of plastic stuck i main jet.

cleaned and fine after that.

yes found out the problem!

the guy who fixed it said that it had a bearing and seal from a gp fitted onto the sx crank, which caused the seal to eventually blow

was rebuilt and so far its ok!
