Default Fox Bicycle Motor?

I just acquired this motorized 80s Ross Snapper BMX bicycle powered by a 1983 Fox bike engine, built by Fox Manufacturing in Arkansas. The company was known for model airplane and RC engines. They made this bike motor for one year only. I believe they were forced to halt production after a lawsuit from Puch, but that part is just rumor. I have it running now but with some questions. I have some tuning to do because it lacks power. The instructions say . . . "There are two needle valves on the carburetor. One at the fuel inlet for high speed and one on the opposite side for low speed. I only see the high speed and not sure where it should go - how many turns out for baseline. Also can find the so-called low speed. I quickly cleaned the carburetor in my ultrasonic and blew it out with only rudimentary disassembly. Anyone familiar with this motors. I'm new here - so it not letting me post pix - or I'm just stupid!

As I understand it, you have problems with the engine?

If you have problems with flavorings, then you need to contact the repair service. I just think that if you want to do something yourself, you will break it. Or connect something wrong. Just my friend when he just bought a bike, he decided to tighten the brake (it seemed to him that his brake cord is too weakly stretched). Then, he was driving on the road and almost crashed into a car due to the fact, that his brake failed.
