Thanks Max,
If I pull the carby down I would give evrything a good clean so that should fix it. I always give the tube a good clean with carby cleaner. I was trying to avoid it because I couldn't be bothered

Hi Lawncutter , yes Norm is right if you have the gx120 engine already then buying the clutch with a 3/4 hole would be the easiest
solution , but if you first need to buy an engine get one with the 20mm 5/8 shaft like Loncin or Lifan or Honda etc.

Cheers
Max.

Yes it can't be the Diaphragm Norm,Why it's not the diaphragm:If the diaphragm valve is open or closed the primer bulb
should still return after being pushed , it must be a blockage on the pickup screen or blockage in the circuit to primer.

From memory that plastic fuel pickup tube in some of these has a check valve ball but most don't ,I usually remove the
plastic tube under the carby and blow the tube and carby out with compressed air.

I used this drawing below to show the red fuel flow to primer on left side.

Cheers
Max.

Hi Lawncutter 45 welcome here, but I don't think you should get any help from us poor Victorians seeing we gave you $600,000 so you can run the Commonwealth Games at our expense. Only joking. I think you can buy a clutch half to suit the 3/4 shaft. I'm not really up on the SB but I think I have heard talk about that

Thanks Max,
Yes I wasn't going to bother too much with it, it is obviously a sticky diaghragm , so I will stick a kit in it and see how that goes. It belongs to a mate of mine, I wouldn't bother with it normally but I will get it sorted for him
