Clay 5 #1 Posted August 7, 2016 Just put a new connecting rod in my 310-8 kohler mag 10. It been in my garage off my tractor for about 3 years. I decided to fix it and have it back on and it runs with starting fliud. Have no fuel coming out of the pump when mounted to the engine but if i take it off and operate it it pumps fine. Just dont get why it wont pump when mounted to the engine. Any ideas guys? Share this post Link to post Share on other sites

squonk 43,887 #3 Posted August 7, 2016 If it's mounted correctly, bad cam lobe. If that's the case, install an electric pump. 1 Share this post Link to post Share on other sites
953 nut 60,204 #4 Posted August 7, 2016 I presume this engine ran well prior to having the rod go bad, therefore I would guess the cam lobe is good. Is there a good flow of fuel from the tank to the fuel pump? Is it mounted right side up? Share this post Link to post Share on other sites

Clay 5 #7 Posted August 7, 2016 Thanks guys took it off again for about the 10th time Reinstalled tried it and no good. Tried ut again and all of a sudden started pumping. Next problem start function not working have to jump the solinoid to start it. Bad switch? Dirty terminal somewhere? Thanks for the help 8 minutes ago, skrusins said: Bad pump?

Have you taken a small jumper wire from the battery positive to the small terminal on the solenoid to see if it closes? Share this post Link to post Share on other sites

There are 2 small terminals one just sparks a little and one will turn it over when you go from positve at the battery with a small wire 1 Share this post Link to post Share on other sites
953 nut 60,204 #12 Posted August 9, 2016 Clay, the one that sparks a little is a grounded terminal, normal.Now you have proven that the solenoid, starter and associated wires are all good. Take a look at the starter circuit in the wiring diagram in the manual, follow the path. Share this post Link to post Share on other sites
953 nut 60,204 #13 Posted August 9, 2016 Could be the 15 amp fuse on the RED wire, could be the PTO switch TAN / PURPLE wires or it could be the clutch pedal PURPLE / LIGHT BLUE wires. If either of these is open or wires disconnected or the fuse is blown it will prevent the key switch from operating the solenoid. Share this post Link to post Share on other sites
