Jim Sheaffer 11 #1 Posted January 1, 2024 I've got a 310-8 k241 with a horribly worn throttle shaft. Before I tear it apart, can someone tell me if the throttle plate screws are staked in or locktighted in? I actually bought an Amazon replacement carb that has all the correct linkages, but the throttle bore is about .020 larger than the original. I'd really like to stick with the factory unit if I can. Many thanks in advance, and Happy New Year!! 1 Share this post Link to post Share on other sites

It's slow delicate careful work. 11 minutes ago, Jim Sheaffer said: stick with the factory unit Definitely advisable. 2 Share this post Link to post Share on other sites
Jim Sheaffer 11 #3 Posted January 1, 2024 Thank you sir. Better to ask here than to possibly ruin the carb. I'm pretty good with a Dremel, but my hands aren't as steady as they once were. 1 Share this post Link to post Share on other sites

One of the things I do is rebuild the older Kohler carbs. I'll PM you this morning with details. 1 Share this post Link to post Share on other sites
rmaynard 16,290 #5 Posted January 1, 2024 An old small engine mechanic once told me that he removed the screws by turning them counter-clockwise 1/8 turn, then turn back clock-wise. Continue this procedure until the screw comes out. The other advice is be sure that the flat blade screwdriver fits the slot in the screw. Personal note: When you finally snap the head off the screw, I have a box of replacements. 2 2 Share this post Link to post Share on other sites

Continue this procedure until the screw comes out. I find this works but only if the worker that staked the screw was not feeling a little overzealous that day. I've seen some that were hit so hard the screw had started to split out. 😳 That's why I went to the Dremel tool to grind off the back of the screw. 1 hour ago, rmaynard said: The other advice is be sure that the flat blade screwdriver fits the slot in the screw.

Good info there. 2 Share this post Link to post Share on other sites
