I am having problems with my dt25 at idle and high speed, what I have done to try and diagnose the problem while the motor was running on the flusher at home I pulled each plug wire on each cyl. top responded middle cyl. responded but the bottom cyl. is not hitting thought it is sparking just not responding when I take it off the plug and put it back on, now my next question is does this motor only run on 2 cyl's until it hits a certain Rpm or not I have rebuilded the carbs and check the Fuel Pump and all seems well. Any suggestions?
