Bull 33 #1 Posted August 24, 2023 Hello Everyone, I just wanted to update you on my issues with getting my 417A running again. After throwing my hands up a couple of times I started to relook at everything. Come to find out that my intake valve retainer spring had cracked in half. That's why the carb was spitting back fuel when I tried cranking the motor. That's also why my compression readings were so off. I pulled the head to see if there was any damage done to the intake valve but luckily it was fine. I ordered a new a new spring cap and when that arrived I compressed the valve retainer spring, added the new cap, and very carefully reset the retainers. I added a new head gasket and torqued it to the suggested specifications. With all the issues with the carb I ordered a replacement through I savetractors.com. I then changed the fuel filter along with some of the fuel lines and spark plugs and crossed my fingers. She fired up and after that I finished replacing the baffles and shroud and went out and mowed the lawn. I just wanted to thank everyone for their help and guidance tin helping me troubleshoot this problem. Regards, Bob 4 6 1 Share this post Link to post Share on other sites

Not rebuildable? Share this post Link to post Share on other sites
Bull 33 #4 Posted August 26, 2023 Hello, I really needed to get it back working or pickup something else. I was able to get the valve retainer spring cap fairly quickly so I decided to order the carb to save time and possibly avoid some other issue with rebuilding it.

Hopefully that new carb will treat you well. If you want me to check over and rebuild the original Kohler carb send me a pm. 1 Share this post Link to post Share on other sites

Glad you were able to get it worked out, It is a good idea to re-torque the head bolts after your first operation. Share this post Link to post Share on other sites
