RE: YS-91SR Engine Problem
I do have a filter installed. Finally, because of your message talking about a hydro/vapor lock, I disconnected the fuel lines from the carb and after about 15 minutes of trying, finally the engine turned over normal. Now with the one way valve installed the engine ran normal. I had not set the rev limiter, so I did not hover, but the engine ran fine at high power.
Thanks for the help. Now to setup the 611 better and set the rev limiter in the 7100R and she will be ready to fly.
