857lover 291 #1 Posted August 6, 2022 (edited) so i have a k301 and it starts and runs until throttled up and when you push the throttle cable back in the governor arm doesn’t move this engine was not on a tractor was on a log splitter so i’m wondering if this is even set up properly and when you do get it throttled all the way up it seems a little to log and it backfires makes all sorts of popping noises and such Edited August 6, 2022 by 857lover Share this post Link to post Share on other sites

Also pull the needle out of the top and spray down into the hole with starting fluid. Have you pulled the spark plug, verified consistent spark... etc...?

I'd be pulling that carb bowl and needle as soon as possible. Whatever you do... don't continue to try to run the engine in this condition... the problem isn't magically going to go away... When is the last time you changed the fuel filter...? Could also be a bad fuel line somewhere, sucking in air... There appears to be fuel leaking out of the fuel pump inlet line right at the fuel pump nipple. I would check that out ASAP...

Snoopy11 5,714 #4 Posted August 6, 2022 Last comment before I go slither back under my rock... While you are diagnosing, I have found it helpful to pop the governor arm off, and manually work the throttle, being careful not to exceed 3,600-3,800 RPM... which I can tell by ear, but you may want to use a tachometer just for good measure. Also, verify that the carberator is physically tight to the engine block, and that the gaskets at engine block are not crumbled, as this would pull more air into the carb and cause such an issue. Also, if the carb float is sticking, this could cause such an issue... only way to fix is to dissect the carb and spray PB blaster on float parts. Again, LOT'S of stuff to check and verify... but don't just err on the side of fuel, it could be a spark issue as well. Best to verify the easy stuff first... but as I look closer, am I seeing evidence of fuel on top of the fuel pump? Don Share this post Link to post Share on other sites

Don no it’s a little oil and i have pulled the carb it looks alright but i’m not sure why the governor arm isn’t moving to close the throttle plate after i push in the throttle cable to throttle down Share this post Link to post Share on other sites

Snoopy11 5,714 #7 Posted August 6, 2022 If you look at your choke cable, it has a clamp near the end of the cable... I don't think the throttle is any different... Don 2 Share this post Link to post Share on other sites
Snoopy11 5,714 #8 Posted August 6, 2022 How much clearance is behind this wiring harness... could it be prohibiting movement in this area...? Don Share this post Link to post Share on other sites
Snoopy11 5,714 #9 Posted August 6, 2022 This is the idea that I pulled from for my K341, and I have installed them on other engines as well... See where the cable is clamped... This is just a Peter Lena type improvement, but, I am very concerned about that wiring harness being where it is on your engine... looks to me like it could cause issues with movement... (notice in the above picture, the harness is ran IN FRONT, not behind the cable-to-governor transition)... Don Share this post Link to post Share on other sites
daveoman1966 3,762 #10 Posted August 7, 2022 This is my C-160 Auto...k341s engine. The throttle cable is clamped on the stud for the breather/vent. 1 Share this post Link to post Share on other sites
