G3 Engine Build Up Problem - Help Please

[Colin F]

Check that your crank is in line.
These cranks are built up from 5 parts, 2 flywheels, crankpin and 2 shafts and everything needs to be accuratly aligned! [:0]

If you have access to a lathe this is the easist way to check it, if not set it up on two vee blocks and check with a gauge.
There should be no more than 0.001"- 0.002" error!
