The thing is I do have something to lose as it is working well enough to cut the grass at the moment as this is the way it has always run since we got
it second hand. If it wasn't working at all then I would have had it in bits long ago!
Don't get me wrong, I'm not worried at all about the technicalities of stripping the carb - I have the exploded diagram of the entire
engine and as you say there's not much to it. I've previously rebuilt gearboxes and have reconditioned a couple of 16 valve twin cam
cylinder heads before so this will be a doddle. I just don't like going to the effort of stripping it all down without at least using new
gaskets and seals when I build it back up. The diaphragm is £2.23 and the inlet seal is £2 to it's just not worth doing the job without
replacing them in my opinion. I've got little enough time to get on with my Locost without having to repair the lawnmower so my aim here is to
rebuild the carb, replace the pull-start clutch, renew the throttle cable and renew the air filter. That should keep it going for a couple of years at
least.
Good news is that I got to spend a good 4 or 5 hours on my Locost today. Got the rear luggage bay cover 90% completed with just the two corners to
pleat nicely round the curve now.
Cheers,
Craig.

Craig,
Had a word with Russ today and he says it's probably the diaphragm. You'll need to separate the carb and tank and hold dia up to the light
(while stretching it slightly). Even a pin prick hole is enough to make them run rough, so replace.
Yet another suggestion for you to look into, I'm afraid.
ATB

Thanks Simon, that's pretty much what I'm expecting to find and I received confirmation today that my parts have been dispatched so I
might tackle it tomorrow evening.
Cheers,
Craig.

Another vote for the diaphragm, my parents B&S mower had the same symptoms. New diaphragm sorted it out.
Not too dificult to change either. 
I've lived a life that's full.
I've traveled each and ev'ry highway.
But more, much more than this,
I did it side-ah-ways.

Purrrrrrrrrr!
That's the sound it's making now!
Replaced the carb, diaphragm and gasket along with a new throttle control, air filter and starter clutch. What a massive difference!
Thanks for your advice all, much appreciated!
Craig.
