Many thanks for all you replies and information

the transition from idles to mains is fine.
At cruise however it actually feels like it is almost bogging - sort of struggling. You can push through it easily enough - but running at apx 9-10 a/f ratio at cruise cannot be good for the engine.

I will start by going down on the idles to try and lean out the idle circuit, maybe also take a look at the idle air screws as well.

next would be to try and richen up the mains for more power - either by larger mains or smaller air corrections or a combo of both. no doubt this will have some effect on the cruise again....I will focus on the idle jet aspect first.

i am very close to PMO spec jetting as reccomended by Mr Parr - so perhaps another fax to him is in order.

thanks
