  1. Hope all is well! I have a 1989 Sears Craftsman with a Kohler Magnum 18 HP engine. Unfortunately noticed the other day that it has a plume of fuel coming out of the air intake on the carb. I have cleaned the carb out out and re-adjusted all the needles to manufacturer specs after the carb cleaning. Any ideas what might be causing this issue?

  2. How do you find the correct torque setting for tightening the head down? I bought the video thinking it would have this kind of info.

  3. Your valve was not stuck at all ! The valve seating had come loose, and if just pushed back in and  left will again come loose , a quick fix!  would be to lightly centre dot around top of seating to hold it in , but that is a quick fix as usually the block wears and will need further work

  4. my lawnmower won't start. I have cleaned the carb, checked for spark, it has good compression, valves are not stuck, kill switch is working properly. what else should I check? Thank you for any help you can offer. I like your videos.

  5. That engine is it a briggs and stratton 3.5 classic ? i have the same engine on my lavor petrol jet wash but i have had to take the head off to do a decoke and clean up the valves also will be doing the carb diaphragm and gasket oil and plug do you no what the head bolts get torqued down to as i can't seem to find that info on the net thanks oh i have subbed your channel
