Removed the fuel shut-off plunger from the solenoid as the coil was bad, cleaned all the jets, the Kohler 2 cylinder ran and idles better than it had in years, same Japan carburator.
I ha e a question for you. Have pretty much the same engine on a lincoln ranger 8 welder. I was cleaning the carburetor and dropped the float needle in the bottom half of the carburetor which goes into the block. How can I get it out?
I have a ch730, my motor seems to flood on start up backfire of couse, once running it never misses a beat. And always starts whem warm. Only hard to start when cold.. Please help 😊😊
After 20 minutes of operation (motor cultivator) the engine (Kohler CH395) starts to give and reduce gas and then shuts down. After that it will not light up for 5-10 minutes. Most likely until the engine cools down and then starts again and runs for a while until it shuts down again. What is happening?
Keep in mind I would have to see it and be there when it’s running to see if there’s problems Have you taken the carburetter part and cleaned all of the offices It is possible that there’s something clogging one of the Jets(ports)but only after a certain amount of fuel goes through the carburetor After it shuts off is there fuel in the carburetor Could be a crack in the fuel line or there’s something wrong with the fuel pump but it’s not supplying fuel to the carburetor Have you replace the spark plug as possible on the spark plug it’s up at the gap separates because there’s a crack in the actual plug Unless I’m there I cannot give a definite answer of what it is or what it could be Sorry Hopefully this helps or gives you something else to look at Remember almost all small engine problems is fuel fuel fuel After it shuts off and will not start is there spark? After it stops running if you pour fuel directly into the cylinder will it fire over and run Will it fire over and run if you pour fuel directly into the carburetor
I had that issue with my red-face welder. The problem was incorrect timing from the distributor. A hammer and long screwdriver to move the distributor solved the problem.
Hey Ray, thanks for the details! I can't seem to figure out where the fuel solenoid wire is supposed to be connected to. I know it goes under the cover to the bottom sonewhere. I have white, yellow and green not hooked to anything. Also a thin red wire unhooked. Any help?
What does this solenoid do? My 26 HP V Twin will run smooth but is bogging, not making power when the blades are engaged. Blades turn free and wind down normally.
The fuel solenoid stops the engine from running on or knocking after you turn the engine off The biggest problem is sometimes Seized in the off position and won’t allow the engine to start
@@citizendick6087 Mine does the same. (CH740) Replace the shut off solenoid and like he does in the video, check the main for obstructions that keep the plunger from fully closing off the fuel supply. Or, just replace the Kohler crap with something actually reliable, like a Honda or B&S.
my stump grinder has this 25hp engine and some times it takes ages or wont start it says on engine b for switching engine off make sure throttle is midway could this b y mine wont start as i stop engine when its on idle
Hi Paul I have a recall with a 25 hp on it too it just shut off on full throttle I can’t get it to restart I replaced the fuel pump I’m wondering how you made out with yours
Good news is it’s only one of two things fuel or spark I unfortunately to check the system there’s at least 100 different things you need to do to rule everything out Your only advice I can give you is fuel fuel fuel 99% of the time it’s the fuel The only time I’ve ever run into Spark being an issue I was on a tapping machine it would run for three or four minutes and then stop because the spark plug had a crack in it but it looks new so no one replace the spark plug Is the fuel system filtered? If it is not it’s highly likely that there is a small particle clogging one of the Jets or orifices in the carburetor Hope this helps Ray
Cool. Thanks! Like others, I was out of ideas. I cleaned off the solenoid plunger, but didn't realize the brass part and the jet were under there.
Thanks for the advice. This actually worked for me after doing so many other things including replacing fuel lines and fuel pump.
Thank you for taking the time to comment I’m glad that it worked out for you
Hooray

The Japanese carburetter is much better than some of the other carburetters out there

I WATCHED YOUR VIDEO👍👍👍👍IT IS NICE TO REPLACE ORINGS TOO,
Awesome video!
Thank you for your nice comment and also thank you for taking the time to comment. It is much appreciated. Ray

Have you taken the carburetter part and cleaned all of the offices
It is possible that there’s something clogging one of the Jets(ports)but only after a certain amount of fuel goes through the carburetor
After it shuts off is there fuel in the carburetor
Could be a crack in the fuel line or there’s something wrong with the fuel pump but it’s not supplying fuel to the carburetor
Have you replace the spark plug as possible on the spark plug it’s up at the gap separates because there’s a crack in the actual plug
Unless I’m there I cannot give a definite answer of what it is or what it could be
Sorry
Hopefully this helps or gives you something else to look at
Remember almost all small engine problems is fuel fuel fuel
After it shuts off and will not start is there spark?
After it stops running if you pour fuel directly into the cylinder will it fire over and run
Will it fire over and run if you pour fuel directly into the carburetor

I have the wiring diagram I could send it to you
I gut it from kohlerengines.com

Rays fix thank you. Now I understand.

it could be that
if its not the problem it will come out without a problem and if there is a large amount of run hours it should be cleaned

Just snip the fuel solenoid and make sure you install a full shut off on your fuel lines. Problem solved!
That is not what the fuel solenoid is for. It is to prevent engine run on after the spark is cut off.
