I have 2006 bf50A honda four stroke motor on my pontoon that I purchased from friend after been sitting about year in back yard . So here is where my problem begins lol . Engine idles arond 1100 ram if I turn it down to idle around 950 - 1000 shaker really bad . I replaced spark plugs, gas lines...
I have same problem i replaced fuel with new put some seafoam to help clean the carbs. My engine idle arond 1000 rps but sun i push the throttle past half it kills the engine . I guess next thing is take off carbs and clean them . Any tips or suggestions will be appreciated kindly. Thank you in...
