Have 14 hp K motor for my PK. Was going to use another I had picked up instead, but found it was not as good as shape on some things as first thought. SO, now have orig engine all apart and gonna rebuild it. Can't decide if I wanna pull the balance gears out for good, always many opinions on those. Think they will stay out.  Most of these old engines I have need a fuel pump because they are missing those when purchased. I'm hearing No kits available for metal pumps now anyway and plastic ones not so good plus lots of $$ to buy. PK's have gas tank above the engine and I'm thinking I should be able to run a gas line correctly to the carb that won't need a pump. What think? Anyone ever try this?  I have a small Wheelhourse B-80 that I did that too and it runs fine, no issues. It is a K 8hp engine. I have Briggs engines in my MTD's that also are gravity feed and no problems.

as long as the back tires are aired up you shouldnt have a problem i have an international farmall h that is gravity feed into the carb and as long as the tires are full of air it runs fine

Only one way to find out for sure :D

 

I have been tempted to test one out, but just haven't yet.(some day lol)

 

Also Just recently someone found this company in MA that remakes kits for the Kohler (metal) pumps here is the link http://maritimedragr..._automotive.htm

 

Scroll down to the green section and click on Fuel Pumps, then next page has a button Kohler fuel pump kits

Unless there is something special in the float and needle that requires pressure for it to fill it should work on gravity feed.

OK, I am officially confused about this fuel pump issue. My Cub has a K301 and it is just gravity fed and has no problems. So, some of the K

 

engines need pressurized fuel to get past the needle and seat?

I'm with Larry: if Chris' great Kohler fuel pump resource can't help you, you could always put on an electric fuel pump.  Otherwise, you can probably convince it to work on gravity feed.

Geno, I don't think that the Kohlers need pressure to get past the needle.  The carburetors are nothing more than a Walbro or a Carter/Kohler, and used everywhere else without fuel pumps.  Somebody correct me if I'm wrong, though, because I know Kohler did modify their parts.

I have  a MF16 with a K341 fuel pump on it quit. The fuel tank sits higher than the engine. I just took fuel pump off put a plate over the hole ran fuel line right to the carb and it runs just fine.

My 1971 pk runs great with the fuel pump unhooked and plumbed gravity fed fuel no problem

My understanding is that they only need a fuel pump if the fuel has to be lifted or pulled from the back of the tractor. If the tank is pretty close and higher than the carb then no need to run a pump. Something else that helps even with a pump is to alwasy keep the tank topped off.

Update: Ordered that cover plate, is actual Kohler part and came quick by UPS of all things!  No gasket in it, would think they could have thrown that in. Be awhile before this goes together, but seems all in order.

That is one way to check if pump is bad on K's tank above motor. I know of no float carb needing pressure . In fact The only thing comes to mind is injector motor.

I more or less did the same thing with my MF16, runs fine.
