Hi Joe,
I have a couple of clutches that came in the spare parts with the shipment of 100 kits that were received last week.
I am really only selling kits, but will offer parts as necessary for failures on the kits. I do have a very good source for parts in China, If you could send me a photo of the clutch and housing assembly on the motor you are referencing, I will see if what I have is what you need.
This is not the same gearbox as offered on the Grubee units.
I will also be offering a rear engine kit in the near future. I will check out the

Good hearing from you.

After sending pictures of my needed parts, I never heard from them again. So I guess their parts are for "replacement" only, and not for sale!
This is something everyone should consider if they are going for the 4 stroke. After reading posts here at MBc I understand this was also a problem in the begining with the 2 strokes. Word to the wise? When shopping look to the availability of parts, not just the assumed "LOWER" price. Hope this helps,,,,someone,
