Hi Guys--------Hello Rattlebattle---Alan R responding allbeit a little later on as I've been out in the workshop most of the time since posting that last item at 11.30am.....Regarding the Honda Moped conundrum ( A rear engine one is a P25 by the way-) if the plug is dry then what's the problem ??.....As you already know the answer to the question then a clue for us would be useful please.....You correctly identified my clue as being a Bullet '65 and you were within the proverbial cat's whisker with references to the decompressor stuck open or the tappet adjusters tightened up......but the answer could easily apply to any engine with poppet-type valves sitting on fitted seats and that is}------ valve seat recession...... What was so galling at the time was, as I mentioned to you earlier everything was normal when I stopped the engine by using the decompressor of course...I then put it onto TDC Compression and went off to enjoy the show......If the decompressor or the adjusters were at fault they would have made themselves known at that particular moment.....The ride over from Telford was normal and no hint of any pending problems at all....Apparently a batch of 'Indian Home Market' Cylinder heads had been fitted to bikes destined for the European market at the Factory....A 1 for 1 exchange service was on offer if your bike was on the list of frame numbers..Mine was so I had a brand new cyl head assembly fitted and I'd only had it for about 6 months !!...........PS}---I wouldn't have thought of you as "being a bit dim" quite the reverse really.... can't see why you put that in ??...Best regards --A.R

OK, I'll give you a clue. The engine was a pushrod OHV and apparently it just stopped with a clunk- bit of a giveaway really......
FWIW I offered Johnnie Martin my expert diagnosis - I was proved right and he offered me a job (declined)! It reminds me of one of those panel games where the contestants are given a bit more info until they guess the right answer - a bit like some of the posts requesting help on these forums really. If it were a work environment I would have designed a simple questionnaire setting out the information needed for a speedy diagnosis. What model, circumstances leading to the fault (often the fault is self-inflicted by the owner working on the bike), what modifications - if any - etc. Sometimes it's like drawing teeth trying to get a full picture and then often the OP can't even be bothered to tell us the outcome.

WOL, Are you testing to make sure you have all the components for the bike to run whilst it's on the centre stand but then after getting ready to go out trying to start it when it's on the side stand?
