Remove the PTO and measure the diameter of the crank threads at the end as explained in the store: http://www.sbtontheweb.com/Merchant2...gory_Code=20-2

Re: need help

i'm pretty sure it's 18mm so is that the big pin and it does have the 6 bolt holes per intake port...and a bunch of people were telling me that the big pin was the green motor and mine is grey

Re: need help

Re: need help

No, that would be a small pin.

Re: need help

ok have another question what lubes the bottom end(crank,rod bearings,etc) are u suppose to add oil to the crank case

Re: need help

2 strokes do not use case oil. It's lubed from the injection oil. www.howstuffworks.com has a good walkthrough on engines.
