Kohler M20 spec # 49544 Walbro Carb

Recommended Posts

I replaced the fuel pump in my Sunstar shortly after I bought it because it was starving for fuel back in July. I also replaced all fuel line and filter from the tank to the pump at that time. It wouldn't start again this Saturday so I pulled the hose off the outlet side of the pump and cranked it. The pump is "spitting" fuel while cranking so I dont think thats the problem this time. It will run while dripping raw fuel through the carb horn.So I pulled the carb and disassembled and cleaned. I am looking for a kit which contains necessary gaskets and a new needle. I did find a small brass orifice that was plugged solid so I suspect that was why she wouldn't run. (pictured in the center) (anyone know what that is?) Also if anyone has a diagram of the guts of this carb should look like would be great for reassembly.Thanks in advance,Tim

Awesome thank you. I was thinking main jet, that would definitely explain the no fire.I think that kit is for the kohler carb, according to this anywayshttp://www.kohlerenginesparts.com/Catalog/Part/1/popular/8/carburetor-kits/0/all/3831/k-series-k321-k361-kt17-kt19-k532-k582-magnum-m14-m16-m18-m20?page=2I think this looks more like the right kit for the Walbro carb, pieces look more familiar anyways.http://www.kohlerenginesparts.com/Catalog/Part/1/popular/8/carburetor-kits/0/all/3833/k-series-k91-k341-kt17-kt19-magnum-m8-m20-mv16-mv20?page=2

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
