Hi all

did a search but not realy answered what I was after

Set up first

MVVS 58 proSport 3/4 run in
MVVS header and canister silencer

2 lipo igniton
prop currently 24/ 10 wood

My problem

cannot seem to get the engine to run anything near like it should

needles from closed turns 2.10 low 4 high!

revs down around 5500 pick up poor, good cooling in cowlbut shows signs of sagging in verticals ie under load, pick up from idle to power is slow

Questions
Silly one first is this a long pipe set up, I have the ignition set for long?
Is the prop too much
do you think there is problem with carb given the seetings. high run adjustment at full throttle on ground makes small difference
have I got an air leak somewhere

I have checked the pressure pipes and other connections and are correct

Any views

thanks Ian
