Thanks to all
Yes I had help, but after all her time and effort to post the photos I an not about
to complain.
I agree the plastic clamps are near useless, I will be replacing them with steel.
Great idea with the aluminum fuel line, never even crossed my mind. I will plan
to make the change if I ever get caught up with my other projects. For now I
prefer the urethane over the neoprene for this application. I have a coil of urethane
and replace the line each spring.

for what it is worth..... after 4 to 6 months of using the urethane fuel
hose with the plastic clamps,, supplied by kolb,,,,, I started noticing
some fuel staining on the engine cooling fins,,,, I turned on the electric
fuel pump and walked around to see,,,, there were leaks on 2 of the joints.
it was bypassing the fitting and hose where the plastic clamp overlapped
itself... long story short,,, if I were to use urethane fuel lines,,, I
would not just put a metal clamp on it and expect it to hold. the inside of
the clamp would not be as smooth as the plastic clamp. which let fuel pass
in the very tiny spot where there was less pressure on the tube.
so imho in my humble opinion,,, to use urethane hoses, in addition to the
metal clamp, I would cut a 1/2 inch of tube and place it on the outside of
the hose. dont use any splits in the 1/2 inch peace, that would give you
uneven pressure on the inner hose,,, leave it intact. it will be harder to
get the hose over the fitting. but will allow for more even pressure
between the clamp, hose, and fitting.
OR someone in the past recommended using 4 or 5 wraps with tie wire, the
center few wraps would create very even pressure between the hose and
fitting.

Picked up the cylinders at the machine shop yesterday and my son brought my f
inished engine mount plate home from school today.
I reassembled the rave valves this evening and the top end looks pretty nice
.
Can't wait to get the bottom end, exhaust and gearbox from Rotax Rick.
