Number three

[Mike Poorboy <bitterrootprop@nidlink.com>]

I believe when Bob and I looked at his U20 that was built by Vern
Colvin.
The number three cam lobe was the one that went bad and he has a oil
spray
bar and the cam oil ports had been channeled. he also said they had a
problem with dropping a valve in one of the cylinders. Bob can you
clarify
this for me.

I also have a cam cover that has been repaired and I believe it is over
the number
three cylinder.

This has become an interesting topic.
