RE: Saito 180 problems
Have you checked the spraybar in the carb? Can be some dirt in the nozzle! Also check the fuelfilter (If you are using this). I have seen that the small fine filters are getting easily clogged with same results as you describe. Also check your tubing, can be an airleakage or just a tank problem. As long as you have fuel, comp. and a working glowplug, everyting should be OK.
