Good evening friends. Recently got a plane with a Limbach L2000 engine. Is
this engine a Type 1 or 4 VW?

It has a single magneto and I want to add an electronic ignition. I
contacted Steve from Great Plains about machining a second set of spark plug
holes in the cylinder heads. He asked me if it was a type 1 or 4 and I did
not know the answer.

Thanks,
Jeff
