it could be a load of things when filters are involved,or an air leak!give the carbs a good clean out,emulsion tubes,everything.check the reed valve rubbers for cracks/leaks,then a plug chop is the best to get the mixture bang on.hth

Thanks will try those things, air screws are at 1 out as it ran better like that 1 1/8 was not good for it.
Also my rev counter seems to react very slow up and down any reason for this? sorry to keep asking
