KyBlue 655 #1 Posted October 22, 2008 The Kohler on my B.. it wont idle down most of the time. It starts okay at a lower idle, but once you throttle up it tends to want to stay there. Any suggestions? carb? Governor? Sorry the somewhat stupid question! Share this post Link to post Share on other sites
saguaro 0 #2 Posted October 22, 2008 I'm new but from reading the tecumseh manuals I'd say check linkage, if not that Id mess with the idle screw up/down in 1/8th turns and see what happens.Could it be running lean at low speed? Share this post Link to post Share on other sites
big mike 13 #3 Posted October 22, 2008 It's very likely the throttle shaft/bore is worn and it is lean. Share this post Link to post Share on other sites
Mith 2 #4 Posted October 22, 2008 What Mike said, or some sort of air leak. Check the gaskets around the carb. Share this post Link to post Share on other sites
KyBlue 655 #5 Posted October 22, 2008 Those are new. Replaced them back earlier this spring, did it before and after new gaskets. Both Surfaces are flat (checked with straight edge) Hate to hear it might be a worn shaft! Share this post Link to post Share on other sites
big mike 13 #6 Posted October 22, 2008 It's pretty common. Share this post Link to post Share on other sites
sorekiwi 761 #7 Posted October 22, 2008 Every now and again my 14hp Kohler decides it doesnt want to idle (runs fine above idle). I remove the idle mixture adjusting screw and spray a shot of carb clean throught the orifice, and refit and adjust the screw. Seems to fix it for another 3 or 4 months, one day I'll take the trouble to clean and fit a kit to the carb. Share this post Link to post Share on other sites
Electro12WH 50 #8 Posted October 22, 2008 Or how freely is the throttle shaft turning? I have a Tec HS 60 that wants to throttle up and not throttle down. Had a corroded carb. Share this post Link to post Share on other sites
KyBlue 655 #9 Posted October 23, 2008 Moves okay. Is there a repair kit or am I stuck hunting a new Carb?? Share this post Link to post Share on other sites
linen beige 14 #10 Posted October 23, 2008 Moves okay. Is there a repair kit or am I stuck hunting a new Carb?? Kohler sells kits to replace the shafts and bushings to take the slop out of worn holes. If you can't find the right parts, PM me. I may be able to put my model making skills back to work and fashion something from brass stock. I'd double check all my linkages and carb settings before I pulled it apart though. Can you see any slop/slack in the throttle shaft? Does the shaft bore look out of round? Share this post Link to post Share on other sites
KyBlue 655 #11 Posted October 24, 2008 Ill have to do a bit of tinkering and check the play/slop in the shaft, look and see what condition its in. Maybe adjust a bit... dont want to do to much cause this thing runs so good...i hate to jinx it! Share this post Link to post Share on other sites
KyBlue 655 #12 Posted October 25, 2008 Well there is side to side play in the shaft...Not much, but there is still some.. No Luck finding a bushing kit.. but there is a Carb setup on Epay.. Ebay Carb - New Share this post Link to post Share on other sites
saguaro 0 #13 Posted October 25, 2008 From what I've read here kohlar aint cheep to fix. But MAN! They's proud o'that carb. Hope you find an easy fix. Share this post Link to post Share on other sites
KyBlue 655 #14 Posted October 25, 2008 Yeah WOT works good.. the fact it wont idle down doesnt bother me to the tune of 176 bucks...yet. Share this post Link to post Share on other sites
saguaro 0 #15 Posted October 25, 2008 It does'nt fix the problem but can you get some kind rubber fitting over the shaft to help seal the leaking? Share this post Link to post Share on other sites
BairleaFarm 340 #16 Posted October 25, 2008 to the tune of 176 bucks I bet someone close to you has a kohler carb and other k181 parts :banghead: Share this post Link to post Share on other sites
KyBlue 655 #17 Posted October 25, 2008 I forgot you had that motor... Wanna sell it all?? I know it needed a cam...but youd bought a rebuild kit and stuff for it.. Share this post Link to post Share on other sites
Rod(NASNUT) 1 #18 Posted October 25, 2008 I used JB weld to fix my throttle shaft :banghead: Share this post Link to post Share on other sites
KyBlue 655 #19 Posted October 27, 2008 Did a bit of tinkering tonite with the carb. Got the low speed idle down, seems to have picked up the top end RpMS a bit too.. We'll see Share this post Link to post Share on other sites
