come on put us out of our misery....fix it and tell us what the problem was

Well, thats a new one on me, never heard of a split diaphragm causing a misfire. Thought you would be able to tell if it was split when you prime it, as the primer will never go hard. Im still going for the carb fault!!

I guess thats so, but you may well not notice a small lack of turgidity

ITS WORSE THAN THAT - HE'S DEAD JIM !!!!!

Yes, as was feared by most, but not by some of the replies (presumably trying to be optimistic?), took it to the Mariner (Barrus - who have under the expired warranty, been very helpful) nominated dealer, and he read it the last rights while I wept.

No compression on number 2 (????)

Must have had carb issues, then seized, followed by much unheard (un-audible alarmed) grinding - and presumably a hefty bill in a few months when they have stripped it, rebored, repistoned dee daa dee daa.

I'm not bitter, i'm the man who wanted to do it right and spent all the money on the proper kit (except I had to concede to a 2stroker because it was cheaper!).

Finalcial ruin (and no Ribbing for the rest of they year - this my only trip out this yeaer so far) is dependant on posible negociation with parties involved.

Sorry to hear about that mate, what are you saying happened? the one cylinder ran lean because of a carb problem? years ago we had that happen on a monarch crescent, that ran lean and wrecked the offending cylinder.looking on the bright side...........
couldn't have happened at a better time weatherwise not that thats much consolation.!
hope its not too dear to fix.
