I just bought it non running the other day and took a chance that the motor is ok. The entire carb and fuel pump were filled with old gas slime. I cleaned everything and cleaned the points. it fired right up. I love these old Kohlers. Today I changed the transmission filter and fluid. The hydro works good too. Tomorrow will be the test drive. After that, the full restoration will begin. I’m glad you like the video. 2 Share this post Link to post Share on other sites

PMed him a week ago but no response yet. Worse comes to worse may try procuring some diaphragm material and making my own. Even bought cheapy kits for the cam lever ones off fleabay to rebuild a couple of those and still no luck getting a working pump. Guessing you got the cock open and it's not plugged in the tank? It was running good for a while but now the carb started surging and it died. There is oil in my fuel filter. I wonder if it is doing through the diaphragm and mixing with the gas. I thought my rubber fuel lines were breaking deteriorating and causing the black color. I replaced the lines and it’s still black. Is it possible for oil to travel back to the fuel filter? 1 Share this post Link to post Share on other sites
WHX?? 49,927 #34 Posted August 30, 2020 Probably leaking back thru a ruptured diaphram. Mine were so old and brittle wouldn't have take much to rip them. Gotta remember the topside the diaphragm sees crank oil. Pattienltly awaiting Buckranchers reply. Share this post Link to post Share on other sites

Gotta remember the topside the diaphragm sees crank oil. Pattienltly awaiting Buckranchers reply. I bet you’re right. I’m glad it lasted as long as it did so I could find out if the trans worked. Now I can tear it down to the frame and have it sand blasted. I’m hoping we can get the diaphragms. I like keeping them original. It pumps a good amount of fuel out when it’s working right.

BHunter 1,700 #36 Posted September 6, 2020 I received the diaphragm from @buckrancher and Rebuilt the fuel pump today. It works great. 1 3 Share this post Link to post Share on other sites
Elliot Garfinkel 166 #37 Posted October 2, 2020 Hi I find myself in the same fuel pump situation I sent a message to @buckrancher hopefully the diaphragm is still available but I was wondering how you disassembled the valves in the pump any advice would be appreciated. Thanks Share this post Link to post Share on other sites
Jennifer 1,877 #38 Posted October 2, 2020 (edited) This is a mechanical fuel pump and it has a different diaphragm but the other mechanisms would at least give you an idea how it goes together! Hope it helps! Edited October 2, 2020 by Jennifer 2 1 Share this post Link to post Share on other sites
Elliot Garfinkel 166 #39 Posted October 4, 2020 Hi all so I ordered a kit from now and then but not sure it will work except for the diaphragm my pump doesn't have valve plate so not sure if rebuild able by me at least.this was after last season running for 2 hrs then system drained and ran dry did motor and tried starting this season.Thanks Share this post Link to post Share on other sites

Maybe a clean and reuse in the rest of it. All that slime is the result of previous ethanol usage. 1 Share this post Link to post Share on other sites
Elliot Garfinkel 166 #41 Posted October 4, 2020 I just ordered kit yesterday looks like right diaphragm I might call them and see if they didnt ship yet maybe send the pump to them put kit money to rebuild.As far as the ethanol I've been try to remove most of it by adding water to gas ,ethanol separates and drain somewhat ethanol less gas.(via utube)Although I noticed a good amount of rust in pump maybe from water in the stained gas.All new lines,filter And tank thoroughly cleaned,Thanks for quick response 1 Share this post Link to post Share on other sites

Not sure if there an issue with rust as I've never tried it. Perhaps others will chime in to comment on the rebuild. @Achto @WHX24 @953 nut 1 Share this post Link to post Share on other sites

Seems they sell a rebuild kit for a pump with a lever. Yours may only require a diaphragm from @buckrancher Brian and a good cleaning. 1 Share this post Link to post Share on other sites

WHX?? 49,927 #47 Posted October 4, 2020 Couple more pics of the rest of the body please Elliot. Does it have a lever? I'm thinking a PO changed it at some time. Yours should look like Bob's BHunter above. His is a eight horse but should be the same. I have no idea how to get those valves out but they should come out somehow. Maybe you shouldn't try but just try and clean in place and flush good with a can of brake cleaner. The white gunk is oxidation from water. Share this post Link to post Share on other sites
Elliot Garfinkel 166 #48 Posted October 5, 2020 Thanks for the response it doesn't have a lever I'm pretty sure it's an original kohler part here is some more pics Share this post Link to post Share on other sites
