Kohler warms up...won't run

I've got a mid 70's Jacobsen GT 1200 with a Kohler cast iron line, automatic compression release (ACR), Model K301AQS, spec 47606D, ser. # 8015920.

Once the engine warms up, it wants to die. It will high idle but won't produce any power. As it warms up and begins to act up, giving it some choke works...more warm-more choke until it reaches operating temperature and then not so much.

The air cleaner is clean and I have had the carb off, apart, and cleaned it with brake clean. No luck...

Any thoughts?

Air is entering somewhere where it shouldn't, bad gasket, loose bolts or nuts......

I agree, air getting in or fuel not flowing to the carb fast enough to keep up with consumption are the two things that pop into my mind.

Need advice removing stubborn mower deck adjustment wing nut

F

Fred_C_Dobbs on Jul 13, 2017

I need to know how to remove a "wing nut" (for lack of a better term) like this one from my mower deck. [URL=http://www.bild.me][IMG]http://s1.bild.me/bilder/110417/2035441mower.wing.nut.jpg[/IMG][/URL] Best I can figure it's mostly hard rubber bonded to a hex nut to make it possible to tighten/loosen the nut underneath by hand. The one just like this only on the other side sort of stripped out. The rubber part seems to have turned loose of the nut underneath. I could tell because when I tried to tighten/loosen it, the wings would jump at increments of about 60 degrees but the adjusting nut didn't seem to be moving at all. One of the wings helped out by breaking off so I decided to take a chisel to it to see if I could cut away the rubber, but that's getting me nowhere. Part of the problem is that I'm working in a confined space because there's only certain angles I can swing a hammer to drive the chisel from. I've got the one on the other side thoroughly boogered up but don't seem to be making any progress toward gaining access to the nut underneath. Any ideas how I might remove enough rubber to be able to adjust this by putting a wrench directly on the nut? EDIT: I should add that in the time I've been pounding on it, the outer rubber part has stopped the jerky moving and now spins smoothly (but with difficulty). I also tried grasping it from the end with a pair of channel locks and trying to 'wiggle' it and maybe slide the rubber part off of the nut but that has ha zero noticeable effect.Read More

Craftsman riding mower w/ B&S 17.5hp - white smoke and gas from exhaust

R

remerbt on Jul 09, 2017

Hey guys, first time posting though I have been lurking a lot. I appreciate any advice in advance! I just bought a used Craftsman mower with a Briggs and Stratton 17.5hp 31C707 - 0230E1. When I checked it out they informed me it had been sitting for about a year - I could tell the gas was old and the oil was black and right at the ADD mark. I started it up very briefly just to make sure it would fire up - it did, and I killed it after about 3 seconds. So I did not notice the issues outlined when I first looked at it. Upon getting it home, I changed the oil dumped the old gas replaced the short fuel line put new gas in it and fired it up. The old oil while very dirty did not have even a slight gas smell. When I first tried cranking it it didn't start immediately but rather spit a lot of gas out of the exhaust. I tried it again and it started and immediately started smoking white smoke. I turned it off, let the smoke clear and tried it again letting it run until the first signs of smoke. I did this probably a half dozen times, with each time getting less smoke and more time until the smoke started. I checked the oil again and it was slightly over the full mark (not even 1/8" over) so I drained a small amount of oil and got it right to the full mark. Still smoking (though better). When I changed the oil I did raise the left hand side up about 5 inches (so the carb was up in the air, and the oil drain was at the bottom). I thought thats what you are supposed to do, am I mistaken? At this point from my lurking it sounds like the next step is checking the needle in the carb. But I wanted to get this started to see if I maybe messed up by slightly tilting the mower, and also if smelling is an adequate test for gas in the oil. It seems like everything I've been reading is saying if the needle is sticking and/or theres gas out of the exhaust then there should be gas in the oil - I dont seem to have gas in the oil. I should also note that the gas out of the exhaust seemed to only happen the first time trying to start it. One last thing, theres a small notch on the throttle about midway, I am guessing that is the choke? There doesn't seem to be a traditional pull choke. When I try to move the throttle higher or lower from that notch the engine dies. Not sure if thats an additional symptom or a separate problem.Read More
