Hi,
Thanks for the replies, Bert is does seem as though that may be the case to be honest. Il try taking the blade off and engaging the deck to see if I still have vibration. This will alleviate problems with belts/pulleys/clutch etc. Although I do think the cutting out is down to either a grotty carb or a worn coil pack.
again, I appreciate all of your comments gents. wont be able to look at it today its almost work time here In the UK
Will post within the next day or so.
