Hello All,

I've been converting two Ryobi's over the past few weeks and am coming up disappointed. I purchased my hubs, spacers, mounts and flywheel machining from wacker engines. Peter has been very good to me and his prices are reasonable. The problem is I am getting substantial wobble out of both units. They are going in a Spitfire and a Hurricane and the spinner backplate wobble is really evident. It appears the either the:

A) Cranks are bent, on the longshaft I used a dial and got .002 run out, loads more when the hub is on and tightened. The shortshaft was too short to get the dial on.

B) The flywheels are not machined right or don't sit right on the crank. The short shaft flywheel wobbles like a gobblin' about 3-4mm out.

C) The Hubs are machined off center or when they are cut to length they were cut at an angle. My prop washers are without a doubt "not square"

It seems that Peter believes these engines are quite crude and wobble is normal......is that so ? should I expect more ? If so, Peter has said he would take the parts back and give me a refund. I hate when things like this happen, I'm not angry at Peter, just disappointed that I am not making progress with my planes.

What do you guys think ?

Mike
