Hi,
I know that when the valves are set too loose on the motors ( 18.5 Briggs OHV single cylinder ,verticle shaft ) that it makes it hard for the starter to turn over kinda like the battery is weak . I know all the other things that can cause this problem to like bad battery , bad connections , bad cam , et. , but what if the valves are too tight ? Can it still act this way ? I normally set the valves on .oo4 thousandths and that didn't fix it . I then set them on .003 thousandths and still same problem . I changed the starter and tried two different starters , same problem . I didn't reset the valves back up to .004 thousandths , left them on .003 thousandths when I did this . Neither starter changed anything , same problem . I know battery is good as it is about a year old and is 400 CCA and started my 20 hp dual cylinder OHV vertice shaft Kohler motor . What are the symptoms / problems of valves being too tight in these motors ? How can you definitely tell if the cam is bad ? It's looking like it, but I don't want to tear into motor unless I have too ! Thanks for any and all help !
