mroman59 Posted April 21, 2011 Posted April 21, 2011 I picked up a 2006 tractor with Kohler 19HP engine and gave it the usual tune up, plug, air filter, oil & filter, fuel filter, battery charge, etc. After putting some starting fluid into the the carburetor it starts right up. The engine has a single throttle/choke mechanism, which I have not seen before. When you lift the throttle control it is adjusting the choke at the same time. I noticed that when I have the trottle in full position the choke does not completely close, so I am wondering if that is the problem or just the design. I am under the assumption that the choke should be all the way closed to cut off enough air and give a richer mixture for starting. Is anyone familiar with this type of linkage set-up on and is the choke supposed to be closed all the way when the throttle is in full position? Thanks, MR
HubbardRA Posted April 23, 2011 Posted April 23, 2011 I am pretty sure that the choke should completely close when the throttle is pushed to its maximum position. Usually the adjustment is as simple as bending the linkage a little. I have run into this problem a couple times on boxstore tractors.
mroman59 Posted April 24, 2011 Author Posted April 24, 2011 thanks HubbardRA, I found the linkage and there is an adjustment screw that can be tightened and pull the choke closed. I put throttle in full position, made adjustment and she fired right up. It was a warmer day though than previous, so I am not totally sure if that solved the problem, but I am guessing it is.
