Hi Guys,

I've tried all the settings I can with the carb but still no luck.

I've sealed the carb but still no luck.

I only can get #6 Novarossi plugs. I'll have to wait & see if #5's make a difference???

I still find it hard to understand how a plug can make such a big difference but as somebody said these engines are different!!

Thanks for your input.

All the best
