By looping the flexible lines up a bit one can add a couple of inches to that height. My MP has mercury in it and is 24" from the level of the mercury to the top of the straight pipes so an engine would have to pull 24" of vacuum just to get the mercury up to the top(disregarding the momentum of the mercury column as it rises).
MOTIONPRO CARB SYNC HONDA CB360 PRO
The Motion Pro manometer no longer comes with mercury as the fluid? I am just thinking up a game plan for when I get home. I could test if it is just the #2 carb by plugging the hose into a different carb, but I am at work. I am not sure if that is the correct flow path but it would explain the cold cylinder. Although the bowls fill, the #2 needle valve is not allowing enough fuel to enter the chamber so when I open the air plug it draws more suction from the manometer than the carb. The only problem with the engine is that the #2 cyl takes a long time to heat up. I have adjusted tappets, timing, carb cleaned, floats adjusted, chain tensioned already. Once the fluid rose to the top I pulled the hose. Instead of starting the bike with the hoses attached like the first time, I started the bike and then attached the hose. After the first fail I replaced the orings greased them up, and replaced the fluid. I checked the intake manifolds and there is no leak. Yes I know I should have bought the expensive Morgan tool but I hoped this would work the same as long as I followed the instructions.

The restrictors are in place and it sucks the fluid out of all four columns. I have the screws backed out all the way counter clockwise and the hose is attached to the #2 carb, choke off engine warm. I bought this manometer for my 77 750F and I can't figure out why it is sucking all of the fluid out.
