I did a conversion by installing a coil from a 8232 D600 engine and i had to grind some of engine and part of the shroud so that the hi tension wire would not rub. On my conversion i had a big surprise when i started it, it ran backwards. I had to try a couple of times before it started properly which is normal now. It is a hit and miss when it starts properly and apart from that it runs good. You can leave the points and condenser in place in case you want to revert back to the original setup.
