Chainsaw Repair

Look in the exhaust port?

I do not know why I don't think of these things sometimes.   Good Idea.

Ok so I pulled the muffler off of my 3450 and off of my 330 and I can see the top of the transfers with no problems at all.    Both the 3450 and the 330 are identical and are quad port transfers.   I also know the 3450 54cc version is a chrome cylinder because, I have done the acid treatment on one I replaced a piston in.  So I guess Mark is correct that both saws are identical except one green one yellow.

It is odd that when I looked up the part numbers they are different for the cylinders and pistons.
Thanks Roger.
