MVVS 1.20 with long pipe
I got this used 1.20 with a long pipe and an OS carb and I am told it is strong and smooth-- It has great compression. My question is there is a fitting in the back plate with a small screw going into the fitting. Is this something that was added (maybe for a pump) after the fact since I noticed the pipe has no pressure fitting--which may explain the fitting. Also, where should I put the pressure fitting? On the pipe or the header? One final thing, What is a good prop for this combo, which is going on an "Icepoint" sport pattern plane.
