I could use some advice regarding my F3680. It is experiencing a intermittent loss of power while under load. This usually occurs once the machine has warmed up, and almost always following a quick reverse. The loss of power is from full throttle to almost stall and lasts about 2 seconds after forward direction has resumed. I have removed and cleaned the fuel tank, and tank tube, replace both fuel filters and fuel pump. I have replaced air filter and cleaned the air intake. The trouble remains intermittent. Can anyone suggest other options for me to try?
Thank you
