I have a 190cc Timemaster that is showing tons of copper in the oil. I have two spare engines available that I can use for a swap. Honda GVC160 Or Briggs 126T02 Two questions. 1. Which one should I install 2. What is the crank snout diameter on the 126T02 And if anyone knows exactly what size reducers I would need for either engine to fit the Timemaster pulley. Thanks in advance.
