Thanks Grumpy & Gadge, I've had 4 goes at this carby with no luck, I think it's a bin job. I see new carbs for $125 in Aust. and about $90 odd from the states, I don't think it's worth the expense & trouble, not even a cheaper repair kit, I had a good run.
I like the sound of throwing a new motor on with readily available spares.
Gadge if you look at the pictures you can see the orig. shaft dia. is 1", the disc boss is a one piece set up that slots into the keyway on the shaft, this is where I'm confused...
Yes, I have seen the cheap 450 series on ebay, I only have 35sqm of lawn now, would this engine suffice?
Am I correct in saying, if I can acquire a disc boss the same as my orig. but with a 7/8" shaft dia. I can go ahead and bolt it all up to my orig. base using my orig. blade disc provided the shaft length is 50mm.
Thanks again for your help, I've got conflicting information from local mower guys
