Hi nick,
They baffle me a bit.
Most people know the top of the crankcase is stamped + or - which relates to the cam and crank gears.
But on the mag engine the sandwich caseing for the timing gears are also stamped in relation to the intermediate and mag drive gears.
The bit that baffles me is, I also have 2 gears here marked +7 for a coil engine cam gear. And somewere in the boxes ive seen a +12 and + 15
Yet ive never seen a crankcase marked over +3 and I've handled thousands of them.
Tony.
