From working with the Command series twins, my experience is that of faulty magnetos (coils). Also since Kohler used so many versions of coils, makes it difficult. The latest coils offered by Kohlers states to replace as a pair, primarily to avoid mixing up different versions. Sounds like you...

As far as testing fuel solenoid, it should have been removed for cleaning. The solenoid needle needs a good seal to stop fuel. You can bench test it by disconnecting solenoid wire then using a couple of jumper wires from a 12V source, connect negative source to the solenoid body and the...

Just a thought, although most of my work repairing is on Command series twins. Most suggestions is what Rivets suggested previously. It definitely sounds like a fuel issue to me. It was mentioned previously that the carb was cleaned several times. Did the jets and emulsion tube get cleaned...

I agree with Briantii. The manufacturers fail to realize or likely ignore the fact the blow by or throwing oil doesn't get rid of the massive sludge in the bottom crankcase, wearing out mains, guides, etc. That never goes away by just adding oil. Ridiculous!!!

I have several agriculture grain augers, with Vanguard 35hp twin series 613400 and Kohler CH940 engines. Both, have carbs with non-replaceable needle valve seats. Also, the Vanguard needle valve is listed at ~$35, while the Kohler needle valve is similar. Find it hard to believe that there...

I agree with all the suggestions. Was the fuel just bought or what you had on hand? If fuel you had on hand, I would definitely look at carb since even fuel will deteriorate in 3-4 weeks. Also, did you check oil level before running the first time? Lots of retailers have boxed...

You stated "solved" but not what the problem you found was. Was a gasket not on correctly or what? Enlighten us? I've worked so hundreds of horizontal Honda GX series and found your symptoms did not make sense. Very much doubt that anything was wrong with the carb.

Are you sure you did the governor adjustment with the throttle wide open?

Neon: That particular Edelbrook is too much pressure and fuel volume. How did you confirm fuel not getting to the carb? I would suggest removing the output side of the fuel pump and crank it over to see if the pump is working first. If the pump is giving you fuel, then check that the carb fuel...

We have 3 post pounders brand new at work that are identical. They all have Kohler CH440 14hp engines. What I'm have a problem with is that all three engines have different Spec numbers. Based on my experience, the spec numbers provides info on features or variants. But these engines are...

This youtube video may help. As Rivets said use extreme caution if doing it this way. If the flywheel is really rusted on other components can break. You can ruin the crank threads and/or nut/bolt hold down.

Almost positive the problem is timing and the flywheel key. The key doesn't have to be sheared off. A slight offset of the key will result is this condition. Also check the flywheel keyway for rounded edges which can add to early key shearing, even with a new key. Sometimes some extra torque...

Try and run after disconnecting the kill wire from the mags/coils. Kill wires on Briggs and Kohler twins use a diode in the line to prevent feedback for the twins. Very easy to damage them.

As someone has already said, pull dipstick and smell for gas in the oil. Based on work I've done on grain augers with Kohler twins, had numerous where crankcase completely full with gas/oil. So much so, that the engine won't even turn over due to extreme compression. If this is the case...

Reading the posts, couldn't find any reference to the having done a compression test. When the new rings were put in, did the cylinder show scoring? As someone suggested, I would hook up spark tester and run it. Look for any signs of missing or poor ignition. Also, I would check for oil...
