Found it Bill. So no real adjustments. Have you ever checked one? Guess you could find TDC and put your own mark on just to double check. ---rick

Rick,
If you could set the ignition at TDC it would be much simpler. Unfortunately, you have to set the air gap and timing with the piston at the ignition firing point, which is before TDC. I've set them many times. It's an easy procedure but you do need a dial indicator to do it properly. CPS sells a dial indicator for about $90. Much cheaper and just as accurate as the Rotax indicator. Hardest part of the job is getting to the pickups. It involves removing the magneto cover and the rotor and sometimes this means removing the engine to get at them.
Often with two cycles, you will get some loading up if you advance the throttle rapidly after slowing down. It's just the nature of the beast.
Bill.

Hey Bill, they say to mount pump below fuel level, my 5 gal tank sits on fuse tube
way down low. Do I need to mount pump down at the bottom of the tank? thanks-----------rick

The ideal position is below the tank but facet pumps will prime themselves if they are not too far above the tank. I have a facet mounted about two feet above the wing tanks and it pumps from the wing tanks up into a header tank above the engine. It works fine. I also have an old facet that I use as a portable transfer pump and it will pump out of a gas can on the ground into a car, lawnmower, or whatever. It also is usually above the gas can when I use it.
Mount the pump as low as you can, but as long as it will prime itself, you will be OK. It will click noisily for a couple of seconds while it primes but that is normal.
Bill.
