Thanks all for your contributions, looks like I'm back to square one with this machine, Last year September I pulled the carb and fitted it with Joel's (CM) SS needle & return spring with modified cap to suit,plus diaphragm. When it was over revving I pulled the carby off to discover that there was actually a chunk missing out of the bayonet type fitting where it fits to the manifold.
I stole a carb off a mower I had with a dodgy frame (Victa Rapier) and swapped the new bits into it but used the original poppet as the rapier one appeared different...only 2 settings but a nifty little peg which would have made it easier to change settings, I renewed the O rings to carby, manifold &starter but not the lower bearing one. I was sure this was going to solve all but not so!
I'm not sure which needle is in it but I'm a bit suspicious of the thread where that goes in so don't want to interfere too much with it ffor the time being.
I had a poke around with the air diaphragm but wasn't sure whether to poke the wire right through it...thought it might have a mesh or something in there. @Sapper, is this what you refer to (Engine Venturi pipe) having been cleaned out with whipper snipper line?
EDIT. Just remembered I did put a shorter spring in the diaphragm cap, just for the heck of it!
