Works perfectly and was the right size
I had a hard time finding the right parts for a 43cc Huskee cultivator. This was a good fit. I put it on and it started on the third pull. I've used it several times and it worked well. I would buy again but I don't think I will ever come across another one of these machines.
only one gasket was correct for my engine powemate 43cc old gaskets still worked and all other parts worked out and by the way in the description picture it doesnt show it comes with the wrist pin bearing but yes it did come in the kit
Worked as described.
