Guys, I collect Mac saws & they actually had quite a few that were like this. I'll see if I can post some pics of my saws that were manufactured just like this one with Right Hand start. I think that they did this so that you could stand on the rest bar underneath of the engine while pulling on the cord with your right arm. Most of my saws have so much compression & are so heavy that you almost have to place the saw on the ground to start. The gear drive saws have so much torque that I have had an instance when i was demoing a gear drive saw at full throttle racing a guy with a big Husky saw & the chain broke, grabbed the 24 inch oak I was cutting & flipped me over the log, I'm about 6 foot tall & go around 245...
