I messed around with the tell – tale, and found a way,
as previous mentioned, to route the plumbing inside of the
spark plug cup, and out the bottom hole.
The may not be “correct”, but it should work, and I didn’t
have to modify the cover.
I went with 1/4″ tubing. Hopefully that size will allow for
adequate water flow to cool the cylinder……. the tell – tale
is the only water “outlet” that I’m aware of.
Prepare to be boarded!
