Make sure barrel and piston are in good working order ,

I use these Barrels and these pistons  , make sure you hone the barrel before starting this job .




First block the cases , as dropping something into the bottom of engine now would mean stripping it all out again .

Believe me i have done , and thought all would be fine , and it cost me a  lot of money to find
out otherwise . ( never again ) if something drops in the engine strip in out !!



fit pin and circlips 





hone barrel if not already honed 


fitting cylinder over the piston rings , oil may help this part 



pull chain through
