RE: Welcome to Club SAITO !
Hi, I need some advice before I send a NIB Saito 220 back to Horizon. I posted a few days ago seeking advice on a different problem which was air bubbles in the line and the engine quitting going past 1/2 throttle. I'm using an Iron Bay regulator due to the tank being above the engine spray bar. The replies to this problem pointed torward the regulator being defective. This was not the case and I found the back plate of the stopper assembly in the fuel tank was stripped out and when screwing in the screw to expand the stopper it had nothing to adhere to. This made the whole assembly ineffective and air was leaking pass the stopper. I solved this problem by going to a coaser threaded screw and the air bubble problem dissappeared. Now I'm faced with a different problem. Once I go pass 1/2 throttle the engine backfires. H.S. needle valve is set at 4 turns out. I tried leaning it but the problem remains. Any suggestings would be appreciated.
