i am sure you can measure the crank a tdc to the top of the cylinder, measure the head volume and work out a compression ratio that will work. Work backwards from compression ratio to design a piston then make a rod suitable for the piston pin height so it doesn't hit the rings, just below the bottom ring.


I have a uncle who has a drag saw complete but not sure on brand and likely won't be pulling it apart any time soon so its of no help to you.

Hi Alastair,
Unfortunately itís a 2 stroke engine so things like the piston design with the flag and compression ratio are an unknown, so I require a sample or dimensions to get a copy made.
