I have no idea what to look for, but need a new crank case for the saw hybrid saw engine. Prices are all over the place.
Think I might have time to break it down today, would also like recommendations for bearings.
Was lazy and didn't take the jug off to press a metal carb tube on it and pulled the head bolts. I now have a Bridgeport, so want to start with a new case and weld/drill it proper.
Started with a CG, stuck a ts400 jug on it with a spacer for squish. It has the correct sized wrist pin bearing, but the jug holes have a tighter pattern. Thought I was being slick, so filled the stock holes with aluminum screws, then re-drilled the head bolt pattern. Well, the holes overlap ever so slightly, should have welded the plugs in, which will be done this time. I balanced the crank with the new jug before assembly, so would rather just transfer to a new case.
A video of it running before I screwed it up.
