Then and Now sells good kits but I have to agree with Paul about using a low pressure electric pump.

You want to go simple, cheap, and ultra-reliable?  Use an inline squeeze bulb like the kind you use to prime an outboard engine on a boat.  KISS.

There were a few different styles of pumps Kohler used (look alike on the outside) so make sure which one you have before ordering. Give them a call if you have any questions. I have had good luck dealing with them

@JOHN C. been using carbole  2 /  3.5 psi electric  pumps for years  , you want the lower pressure pump . never had any  carb  fuel overrun issues , eliminate the issue . pete

I want to stay with original design, I never really liked the idea of the electric pump, the diaphragm pump was good enough for kolher I added a primer bulb on my 314 and I'm happy with it so I was planning on a primer bulb since this machine has the tank under the seat. I've seen then now mentioned in other threads, I'll give them a call today, thanks

 

Any pointers on how to remove the check valves, they look like they're staked in place

 

 

It seems I managed to spend the winter on the marketplace buying retirement projects, the C101 has the most promise and needs the least work.

well dang.....I've spent the last hour or so looking at pumps, heck they cost less than an overhaul kit so I may be nearly convinced myself so swap over. Am I right in thinking with the electric pump I won't need a primer bulb ? 

 

Greasy Pete, I looked at that carbole brand, looks a bit better than typical China bay-zon offerings did you find one that uses 1/4in lines ? 

 

Let's see some mounting pictures for some ideas, luckily I've already got the machine apart so install should be fairly straight forward.

So, where's your shifter boot Johnny?? Now is a good time to address that...

I added the primer bulb gizmo on my C81 - is was difficult to start if it sat unused for a few weeks. I used the open space to the left of the Unidrive dipstick, added a cradle & spring loaded pusher. Works sweet... it is not activated by sitting on the seat.

@JOHN C.  think I used 5/16   fuel line  , not a big deal , also have a fuel filter  just after tank  ,and another  just before carb . agree with @ri702bill  on the shifter boot  , like to  grease the  UNDERSIDE ?  prevents hangups , moves better over irregularities  , like a heavy tye wrap  on the shifter stick  , just above boot  , makes it live longer  . did you  drain / flush clean the fuel tank ?  drop the fuel valve ?  thats easy , new valve and grommets ,  like a dielectric grease on the grommets , makes all  slide points , smooth easy , have not had any fuel issues on my 3 horses . pete

That's slick set up right there. I put one my 314 it sits right behind the engine,

 

The shifter boot is in the mail along with a seal kit for the transmission. The oil was a little brown in the gearbox, so I may as well fix the axle seals while I've got it apart
