Head Clearance for Mac .21

[Plan D]

Andy, I'm still learning on the motors. What do you mean by deck height? At the end of last season I noticed the bearings were getting a little rough. So I ordered some to replace them. When I tried to get the rear bearing out I tore up the crankcase and ordered a new one. I put the old parts with the new case and bearings and this is where I wound up. You guys have been a lot of help. Thanks
