Who is making prop hubs and selling them online? They seem to be the hardest part of the conversion process.

Ive seen some for ryobi/homelites on ebay and they go for very cheap.

.

thee you go....even better!

Carr has most of the popular weedies for running on the magneto.
CH Electronics has Mac, Ryobi, Homelite, and Poulan full electronic conversions or the parts for glow conversions on these engines

I do convert these engines and have all of the equipment to make my own parts. I use 6061 Aluminium for my prop Hubs and Mounts. My price for a machined and polished hub is $15.00

Here is the address for Carr Precision. They do list hubs.
