I just got my new ys110, put on a 15-8 prop and put it in the test stand. I have a check valve between the return line an the tank and the tank line to the carb. The high speed adjust ment is recommended to be 1.5 turns out, but I want it rich for break in so I have it out about 2.5-3 turns. Low speed is out about 1.5-1.25 turns. it starts right up, prop is ballanced by the way. cool we are off...

wow sucks through the little tank in 4 minutes or less, no big deal, I just think we are running rich so no worries.

Question #1. After the first tank is almost done I turn it off, I notice the carb is now full of fuel about 30- second later, so I dont get it, the tank is pressurized, what releives the pressure when the engine is turned off??? nothing? does it just continue to shove fuel into the carb? the manual says not to touch the rugulator. I see 3 adjustments only, high speed , low speed, and the regulator that you are not to touch, factory set at FLUSH. SO is fuel suppose to just fill up the carb after running?

#2 after 4 tanks we are starting to run nice, but the engine quites, I know I am rich and I throttle up and killed it, but now even though I can turn it over by hand, the starter motor will not do it. Maybe my battery was getting weak, or maybe the engine rings are starting to seat and thus this motor will not turn it over.... not sure, I will figure this one out later.

Question #3 so after I am done I start to dissasemble the prop, I dont have my plane yet so I am not sure which aluminum spinner to buy, so I was using a plastic backplate and no spinner at all, just one of those lagre cap nuts that people used to use (maybe they still do), you know the one that you have to turn the starter rubber insert in backward to use to start the motor, well, I take off the prop and the plastic backplate is fused to the prop???? never seen this before, so I try to take it off, then hit it with and wrench, then try to pry it off with a screw driver, no way is this thing comming off, so I take pliers and I am trying to just get this thing off the prop, it is totally stuck, well the backplate breaks, and ten minites later this backplate is finally off the prop, in pieces, so anyone experience this before? I have only ran .46 and .61 2 strokes and have no experiance with 4 strokes at all, is this normal? is an aluminum spinner and backplate a must?

PLEASE HELP, I really appreciate it....
