RE: Running with no pressure line.
ORIGINAL: slodsm
Coming from 12 years of tuning and building full size race cars and god knows how long in RC, I really don't care what a magazine says about it. I know how the system is supposed to work and I know that with no pressure line it is not optimum so I am inclined to agree with cawyman. The vacuum generated by engines this small is not enough to properly draw in fuel except to keep it running. Think about this, 2 stroke dirt bike have no fuel pump and no pressure line, BUT the tank is mounted above the carb so gravity feeds it. EVERYTHING ELSE OUT THERE has some form of fuel pump be it mechanical or electrical. I would not run one of my 400 dollar race motors with no pressure line and I sure wouldn't try to run a 10000 dollar real race motor off of vacuum so why bother trying to do things the way they were not supposed to be done? It's not good for it and that is that.
