Check your email-Sorry about the dog
About the 91fx. I had two over a one month period and returned them. later on I found they were having problems with seals in the remote needle valve. Either way, I dont fool with it. The final solution was a OS 1.08. I have two of those engines. They are the most consistent and reliable engines around. G90 is a good engine or maybe try a Magnum Fourstroke. Whatever! See ya.
