BigNickNY Posted July 21, 2019 Posted July 21, 2019 Hey there! I recently had a Cub Cadet 1811 with a Magnum 18HP follow me home. Needed some electrical work such as some broken bits and a new solenoid and hey, it ran great! Used it a couple days and parked it. Well, went to fire it up today and nothing, checked the oil and lo and behold, it flooded itself to the point both cylinders were completely full of gas, as was the oil pan, lines, and filter. Drained and flushed the system with fresh oil and a new filter and she once again fired right up and ran wonderfully. Heres the part that becomes the issue, pulled it into the shed and turned off the fuel with the shutoff I installed, went to give it a little gas to run it out and it took off on me, regardless of the throttle position it sends the RPM's to the moon until the key is turned off. I can see the throttle cable and linkage moving as it should, but it does little to slow the engine down. I'm hoping its a simple governor adjustment (which I unfortunately don't know how to do) but in the case its not, how far apart do you have to take the twins apart to install a new governor and would gasoline in the oil (from the flooding) cause this sort of thing. Thanks! Nick
puttputt Posted July 21, 2019 Posted July 21, 2019 You have to split the crankcase to replace the governor.
spi Posted July 21, 2019 Posted July 21, 2019 The cable and linkage may be moving but is the shaft and butterfly in the carb moving with them?
the summoner666 Posted July 21, 2019 Posted July 21, 2019 Did you put in a different fuel pump or just use the same one with the shutoff? They tend to leak gas while there running also thru the hole in the crankcase for the pump arm. Let us know....
Brettw Posted July 21, 2019 Posted July 21, 2019 The instructions to adjust the governor are available on the Kohler site. Look for your engine's service manual. It is on the site in PDF format and is free. I would doubt however, that your governor simply went out of adjustment. If it has failed, you will need to disassemble the engine to access it. They are still available, and unfortunately are known to fail. You have been lucky if it did fail, as that usually causes an engine to grenade. I can't see how the fuel would have affected this. I would start with checking all linkages to be sure nothing is hung up. If adjusting the governor doesn't do it, it may mean it's time to split the engine. Although not necessarily a simple task, the service manual will walk you right through it.
BigNickNY Posted July 22, 2019 Author Posted July 22, 2019 I'll have to do some looking on Tuesday when I've got some free time, it was such a sudden thing that it took me by surprise. I'll look and see if the linkage for the carb went goofy or it something is moving when its not supposed to be. Thanks for the advice! Nick
spi Posted July 23, 2019 Posted July 23, 2019 I suppose a stuck float might make it leak fuel internally. But don't see how it would run full open.
BigNickNY Posted July 31, 2019 Author Posted July 31, 2019 Alright folks, sorry for the delay and lack of information. I finally had some free time to get out into the shed and look into the issue. Thinking it might be the carb having an issue I started there, pulled the air cleaner and housing to find my issue. Turns out, the little linkage that allows the butterfly to open and close had come undone and was allowing the engine to take all the gas it wanted. Secured that little rod back down and it runs just fine. Little learning experience considering I was about to yank the motor. Thanks! Nick 1
