just got the K341 on an Ariens S16h running for the 1st time in who knows how long earlier today... tried something that usually works for me as a temporary fuel supply to make sure I had "good" gas getting to it, but today it didn't work.

This one has a primer lever on the pump.  It didn't prime up, so I grabbed a spare "loose" tank and set it on top of the engine, Soon as I opened up the shutoff, the gas flowed thru the pump like it was just a piece of hose.... I think I know, but that isn't supposed to do that, right?  

I searched here and found the Kohler fuel pump kits in a couple of other threads, but there are 4 different kits available... any way to tell which kit I need without pulling it apart to match up the plunger on the diaphragm? I don't want one of the POS  pumps that they sell for these engines these  days....

I usually put an electric pump in the line and don't worry about the non working mechanical pump.  Usually cheaper and easier than messing with the original pump.

Where did the gas flow to? Besure it didn't go into the oil sump. I picked up a NOS Kholer pump rebuild kit at a swap meet last week. They are still atound. Good Luck, Rick

I unhooked the fuel pump outlet hose  where it goes into the carb inlet and as soon as I opened the valve on the temporary tank held above the engine, came out that fuel line.... re hooked it to the carb and the engine took off and ran, I don't really want to put an electric on this machine though I have done so with others in the past.

and boyscout... the website that is linked to in a few places here, shows 4 different kits to fit seemingly "the same" Kohler pumps.... from back in the day were there multiple kits available from Kohler for them as well?

I think the plastic pumps are the best from my experience, the plastic does not transfer as much heat from the body of the pump to the fuel.

It's not that hard to pull the pump apart and check the shape of the diaphram.
