Hi and thanks to all of you who contributed to the original thread (58 replies - a record?)

All is now well. This is what it took:

* Stripped carbs, found one needle jet slightly blocked

* Discovered needles were on top notch so put to middle notch

* Put in NGK B7ES spark plugs

Bingo! Now have great running no misfire and a reliable tickover (gasp)

Thanks Nick

Glad you've got it sorted.The cause of misfires can be puzzling sometimes.
