Ok so I have the machine running a little better but it is still not quite right.
The cylinder and rings were pretty spot on ie no scoring.
I cleaned the exhaust and fuel lines/ filter and it does run better but it still bogs down occassionly and when left at idle it will stall after about 30 seconds.
Before replacing the diaphragms could I get some help with the mixture screws?
If you think that wont solve the problem I'm happy to get the diaphragm kit but want to know the correct model. From what I can see it is a zama carb.
Any tips associated with these carb would be appreciated.
I am pretty sure this is worth fixing unless others have an alternative view. Echo seem to build a decent product


Thanks guys
