I recently bought a 40 hp 4 stroke 2012 model been sitting for a few years might have 30 hours on it it seems to run great on land revs up great idles good cranks up perfect but it has a slight popping noisy coming from the air intake where the screen is I’m worried it might be a valve sticking has anybody ever heard or seen this before al help greatly appreciated
run some seafoam through it
Thanks I’ve been told that stuff does wonders I have narrowed it down to a hose that goes onto the side of the throttle body if I pull the hose of and put my finger over it the noise stops lol
SEND ME THE SERIAL NUMBER
THAT MOTOR MAY STILL BE UNDER WARRANTY
Thanks Chris people like you makes this such a great site willing to take a few minutes and help people out!!!
