RE: Saito shuts off
My Dad had a Saito 45 that was new and did the same thing. It would run for a minute and just shut off. He changed the fuel, prop size and the carb. No difference. He brought it to me to see if i could figure it out. I asked him if he had tried another plug. He said the plug was new and therefore ok. I played with it for a while with no luck. I put in another new plug and it worked just fine after that.
