C-160 starts easily then quits

[RJR49 173]

A few weeks ago my C-160 started then quit. Starts quickly maybe 4 seconds later quits. Afer a couple of those efforts ran fine. Today the same thing happened! I was thinking that the electric pump got tired but if you let it sit for a couple of minutes it will run for 4 or 5 seconds. If I restart immediately it only runs for 2 or 3 seconds so now im leaning towards the filter. Before i start troubleshooting i thought i would ask if anyone has other thoughts.

 IMHO.... Always do regular maintenance before troubleshooting.  

 

If you cycle the fuel pump off and on three or four without starting the engine, that should fill the fuel bowl for sure. Will it stay running then?

 

Have you removed the inlet hose from the carburetor to verify that you are getting good fuel flow?

What is the age of the fuel filter?

When was the last time the carburetor was rebuilt?

All fuel lines replaced?

I dont think the carburetor is the problem. It starts to easily and repetedly. The flow from the pump is the first thing im planning to check.

Could be a fuel issue... could be a spark issue. Use an inline xenon bulb spark checker to narrow down the true source of the issue...

Condenser?

Quick way to check your condenser is to disconnect the wire, if the problem goes away then get a new condenser. The engine can be run for a few minutes without it for testing without damaging the points.

I know I'm probably the only one that has done this, but could the fuel valve be shut off.

It was a problem with the carburetor. I bought a Chinese carb from Amazon.  Had to cut off the choke tab of course. Fired right up.

Do you still have the original  #30 Kohler carburetor? 

Can you clean and rebuild it?

 

My experience shows me that the "inexpensive" one won't last.....

I have a couple of Kohler Carbs i could rebuild but the Chinese carbs are half the price of the Kohler rebuild kits. Other than the choke being backwards I'm satisfied with them. As an aside; I have 3 Honda Motors on various pieces of equipment. All, well over 10 years old. When I start them for the season, snow in the winter, leaf vac in the fall, and my pressurewasher once every blue moon they always start on the first or second pull. I take care of them when i put them away but they are amazing. I've toyed with the idea of putting Honda motors on my two C‐160's if the Kohlers ever die

 But, as good as they are that just seems WRONG!

I can see your logic but I have NOT had the same results of satisfaction. 

At least 4 cheap carbs have gone through this shop. 

Two were from isave. 

 

All. Four. Failed.  

 

They're excluded forever. 

 

Kohler kits are no longer available but I was buying them for about $15. 

 

I'll always spend the money and time to do a rebuild.

When did the Kohler 25 757 01S kit become NLA and are there any good aftermarket kits?

Not sure. I found out a few weeks ago.

I haven't tried any so I don't dare recommend one.

I have a couple that wasn't 2 bad but a couple that were junk so 50/50 chance for me to get a good one. I will take an original if given the chance though. Hate to hear the Kohler kits are no longer available.
