Thanks Norm,
The base does not really have a hole for the muffler, certainly not at all like an ordinary full crank base. The muffler exhausts just beside the sliding plate through a slot in the base. The muffler does not actually protrude through the base. The slot is much longer than the exhaust pipe and has space both before and after the exhaust.
This steel sliding plate (or adapter) is definitely full crank. It has the 4 holes for the crankcase bolts in a square or nearly square pattern around the round hole for the crankshaft . Does the PT base still have the sliding plate?
I won't be fitting a Chonda and definitely not a Briggs although that's what the new Mastercut 600's are. My motor of choice would be a Powertorque of which I already have a couple of good ones.
The current full crank is probably OK, just I do not have many spares and can not get them easily. I already used my only spare side pull starter.
The modified carby brings me back to the needle valve issue again. I only have one Carbymaster type and it is definitely sticking. I'll try to soak it in fuel for a couple of days. Have you had any experience with the 10 for $17 source yet?
All the best
Jeff
