550F jets

<< < (2/6) > >>

Oddjob:
Most likely float stuck and flooding backwards. Check the pipes coming out of the float bowls aren't blocked/trapped. I'd also check the float bowl drain pipes, the brass ones, if those block the fuel has to go somewhere and it's either into the engine or the airbox. There should be a drain on the airbox as well to stop that getting a big problem.

Is the airfilter housing vented to air, in that the engine breather no longer goes to the airbox as it does as standard?

Davelu88:
The engine breather ( big fat tube) at top of engine went to the bottom left of the airbox

Oddjob:
Disconnect it Dave and just vent it to air near the main stand. If for any reason the engine starts to vomit out it's oil, and I've had this when a set of rings broke and the compression went past the piston and put the crankcase under compression, it won't flood the airbox.

Davelu88:
Will do , I see DS sells the 98 jets by special order so I will get some & strip the carbs and look at needle position as well , then swear like **** as I try to refit them  ;D

Davelu88:
Has anyone got ant original 98 jets for sale as DS and CMSL have none .
