Kohler M18 Choke Mod - Purchased Ebay Carb

[Lost Pup 173]

I purchased one of the (really) cheapo clone carbs on Ebay for my 418C. As delivered the choke arm lever was opposite ( facing down ) and the 418 requires the up facing choke arm so it would "pull" to close the choke. Fashioned a small arm and  sandwiched it to the down facing choke arm. Works perfectly, no dimensions as I eyeballed up the travel line from the choke cable to the arm. The 418 starts and idles and runs perfectly.

Great Idea!!  Swapping out chokes usually results in sheared little screws and much frustration

Yep, its almost a given that one or both screws will break or strip. I still do it this way because I found a way to survive it. The threads/hole in the shaft are almost perfect for going back using button head 4/40 screws (or any 4/40 screw) I carefully redrill the old holes and tap for the 4/40 screw. Ive done some 5 of those that way --- jeez, its crazy not to get a brand new carb for less than $20!

 

I recently bought a Massey Ferguson with a K341 engine and its choke arm was even yet more different and the carb on it was completely ruined, so I ordered one of the $12-14 carbs and did the choke arm swap and ---voila!!
