Electric Fuel pump on C-125 Spraying fuel from carb

Recommended Posts

C-125WH

Hey Guys,
First time posting here. Just recently bought my first home, I have an acre to mow. I have my grandfathers old c-125 with a Kohler k-301. I stopped getting fuel pressure and parked it years ago. Recently I got it back out and decided to get it going for the new place. I bought a brand new pump, you know the plastic knock off kind? Well the motor is not hitting the arm on the pump to make it pump. So I bought a electric fuel pump that puts out 3-6 psi. Now the mower somewhat runs, it is flooding and spraying fuel out the front of the carb. Is this because the pump is too powerful, or is something wrong with the carb? Mind you I can work on anything, I work on cars all the time but don't know jack when it comes to carbs. Thanks in advance to any help.

the float might not be closing all the way does it leak gas out the carb when its shut off?

I believe 3-6 psi is what a carbureted auto requires. Too much pressure for the small float on a small engine. 1-2 psi should be plenty.

:WRS:  Always glad to see a Wheel Horse being appreciated by subsequent generations of a family. A new needle and seat in the carburetor should do the job. Lots of "low pressure" electric fuel pumps being used on Kohlers.

That might be too much pressure. I have electric fuel pumps on 3 of my tractors and they are rated 1 to 3 PSI. I haven't had any problems with any of them. Hope this helps.

Bend the arm on the knock off pump.  Throw the electric away.  Keep it simple.

midpack is using a pump that is rated at 3 to 6 psi and it works well, don't think pressure is the problem.

I am using the same pump as midpack. So I am left to assume that it is a carb issue.

I'd bet that its gonna be a bad needle & seat thats sticking, I'm running 5 of that type pump and granted they wont stand for a marginal needle/seat, it has to be a good seal. I had a carb that was doing OK til I added the lectric and then it would stick on occasion, I finally put a new needle/seat in it and that fixed it.

As part of the resurrection process I underwent for my 175, i disassembled the carb to make sure it was clean. I did look at the seat under a microscope at work, it was in very good shape, nice and clean. i had gotten a gasket kit that included a new seat but the original looked so good I left it. i did use the new needle though. maybe that's all you need?

Sorry I haven't updated in a long time on this. I bought another running Wheel Horse and have been using it all summer. I just finished cleaning and rebuilding the carb tonight. It was an issue with the needle and I am happy to say it is running great! Thanks so much to all of you for your help. I'm so happy to have my grandfathers lawnmower up and running.

      So gang, it's Christmas time and my company has extended its forced vacation to two weeks, sucking 7 days of FTO from me. I've got all kinds of things to do for the wifey-poo but what the heck can I do for me?
      I've got two K301s so may as well get out the surgical tools and do a b-gearectomy. The C-125 goes first. Restored that back in '17 and so she's got maybe 75 hours on her. It'll be rather painless and the youngster is visiting so can assist in getting that b-itch up onto the bench. She's already been moved to the garage and the old Kawi and its carb parts moved back to the shed while I search for tiny o-rings. Wish me luck and pics to come. Oh, there is no rattle BUT she's always had a minor knock I chalk-up to excessive end play (didn't measure it back then 'cause I'm bad but, dang!, will now).

      I put together a replacement for the missing clutch handle today.  I like it so much I'm going to make one for my C-175 also!
       
      Now I need to figure out how come it's not staying DISengaged.  It EASILY jumps off the detent at the slightest touch.  It appears to be a new bracket / lever, judging from the paint on it, but I have not investigated further yet.  Wonder if anyone has run into this and solved it?
       

       
      What is the correct routing for the throttle cable?  This just CAN'T be correct!  It's right on the cooling fins of the engine, it's done melted the skin off the cable!  Maybe it's a replacement cable and simply too short?
      If someone could post a pic of the correct routing it would be much appreciated!
       

       
      While looking that over I noticed some oil 'weepage' at the front of the engine.  To me it appears to be concentrated right under the fuel pump.  I presume there's a gasket there that may need to be refreshed?
       

       

       
      The only other suspect is the valve cover but and that appears to be a little weepy too, but  more so the fuel pump. 
       

       
      What say you K301 gurus?

      Morning -  Looking for a carb.  There are plenty of carbs on the 'net, but 99% do not fit because of the choke configuration.
       
      Background info:  Engine - K321S, 14 Horse Kohler.
      Choke control cable is routed to come from BELOW the carb.  To close the choke, pull on the choke knob, the choke shaft rotates counter clockwise, and the finger tab sits at the 10 o'clock position.
      To open the choke, push on the choke knob, the choke shaft rotates clockwise, and the tab sits at the 1 o'clock position.
       
      Where can I get his carb?  Thanks in advance.

      When I purchased my WH (67 T877) it had the incorrect oil bath filter on it (it bent the front of the grill out) I took it off and placed a regular filter using just the oil bath cover. My question is...is it ok to run these Kohlers without the oil bath filters? I know they are better filters, but Im curious if the modern filters are sufficient.

      Hi Guys,
      I’m cleaning the Onan P220 carb on my 520H. It’s a Nikki 146-0479 carb. I was wondering if the main jet needs An o ring and if so which type and size? There was no o ring when I took it apart. 
      Thanks!
