1)I needed to replace the carb as the glow carb was not suitable for gas.
2) I would need to run 11% oil.
3) To use less oil I would need a new rod with needle bearings on the crank pin.
4) The crank pin was too soft to stand up to the needle bearings. I would need a new crankshaft.
5) I would need all this in addition to spark ignition and battery.
I've done a few (2500, 3000's, 4500)...
1) Correct... that's true of all conversions...
2) see below
3) actually, both ends for longevity
4) well, this IS the conversions thread.... you don't need a new crank.... just a "new" crankpin.... the crankpin is hard, but not hard enough... so you heat it up and slow cool to aneal it.... mount it up in a four-jaw or a home made jig.... turn down the crankpin to accept the pressed-on hardened inner-race accesory for your chosen roller bearing (the 4500 pin is already hard enough - no mod needed)
5) see the gas-on-glow-no-ignition thread
