You got a pretty neat forum here, some good info on the old Macs. I'm located in southern WI, so I imagine a lot of you have been to the Brodhead racetrack.
Anyways, I have some projects that will require a fixed head saw engine to be bored over, so I'm looking for machinists who can handle working on them. Preferably they'd be somewhat near where I'm located to minimize shipping costs.
Specifically, I'm working on a Mac 650 geardrive and a Super 250, which are very similar: 2.125 bore and 1.500 stroke, third ports are open. I have a 48890B carb that I want to use, a 5 degree advance flywheel, and want to use the reed components from an MC 49E. I also have a NOS piston, rings, and rod for a MC 91 that I was thinking about using (2.125 bored .040 over = 2.165) but I have a feeling you guys might have reasons not to do that, which I'd also be interested in hearing.
Thanks in advance!
Eric
Eric, I don't know anyone in your neck of the woods that doe's the blind bores. We send all ours to Terry Ives in California who is excellent and a good guy. Maybe someone else knows someone but if you you want someone that does excellent work Terry is your man and it may be worth the little extra cost.
