kohler carb

Does anyone know the thread size of the throttle shaft screws for a carter N? I'm looking to get a pack from Macmaster car but I'm not sure of the size 4-40x3/8 brass seams to stick in my head but......

My bad It had nothing to do with being rude to anyone. That image has been sitting in my downloads file for over two years.
I uploaded the image and hit preview just to see how it looked before adding a caption to Joe.
Only it was the submit button I hit
Then I went to bed

Oh no Ken, I wasn't implying u were being rude, quite the opposite!! A man asks the size and poof u get the size, length and part number! That's one of the great things about this board, there are those like me who want to know and those that do who are willing to share it so we can learn and enjoy too. Sorry if I rubbed u the wrong way

Not taken that way at all Craig-
They can be had in stainless steel as well however given the marginal combustion chamber clearances in these engines that's probably not a good idea should one ever work itself loose or snap off which is probably why they were made of brass to begin with.
This throttle screw head was drawn inside and bedded itself into the cylinder head chamber-

Had a steel screw been used instead this piston probably would have been destroyed, since the screw was soft enough to give a little only cosmetic marring to the piston top was the result-

Good deal! What did you use to clean up the combustion area up with? It looks like new

Ken,
I like your relief job on that block!
