Force 150HP has new/good starter, Good Battery but will not turn Motor over. I pulled the plugs and the starter will spinn the motor all day long.
Compression tested all five and got 120 -- 130lbs
Could this be a timing issue?
Tried turning flywheel while plugs were in and motor seems to be building more compression than it normally did before this problem!
Any suggestions???
 
Sounds like a weak battery or a weak starter.
Timing could be a problem if the flywheel key sheared.Get the battery and starter tested at any auto store.
You sure the comp is good?Spark good?J
 
Probably 95% of all starter problems is electrical. Is the battery fully charged? Check all your connections. They must be very clean and tight. Check the lugs very closely for any signs of corrosion. They can corrode inside where you can't see it and cause the problem you are having. If you know how to do a voltage drop test you could check them that way. Another way would be to temporally substitute the cables with jumper cables. If all the cables have been confirmed good, try jumping the starter solenoid. Just because it clicks does NOT mean its good. If you are sure the solenoid is good have your battery load tested, regardless of age.
