Hey Sean, this is the degree wheel that I use. It's originally set-up to time the camshafts on Ducati V-twins, but it's almost perfect for use with RC engines. The center hole is 6mm, and it needles to be drilled (reamed) out to 7mm to fit over the big section of the crank in our engines. I use a combination of a flywheel collet and a prop washer to bolt it to the engine, and I've also had a jig made to hold the engine, and telltale solidly for accurate timing measurement. I have a picture somewhere of the jig and equipment I use to measure port and induction timing. I'll post it when I find it.
