First off let me start by saying that I bought a kt19 to put in a 317. I got it running this week putting in a few new gaskets and seals where I could without completely tearing it apart. Got it in and all hooked up and it seems to be running ok but getting hot quickly. It idles fine and runs wot fine but the plugs are white from only 5 min of tinker time checking the charging system. So I started to tune the carb and I can completely screw in the idle screw and there is no change in the engine idle. It runs the same bottomed out as it does 1.5 turns out. It seems to me that it should about die if the idle screw were to get turned all the way in. 

So so my questions are:

why am I able to turn the idle screw in and out without a change in engine rpm?

secondly, is the carb from a kt17 series one the same as a series one kt19? If so I will swapmcarbs to a known good one from the 17 and be done with it. If they have different Guts tho I'll need to keep trouble shooting.



thanks mitch

 

if this isnt the right place to post this please move it.  I would like to get this thing in shape for sunday.

With no changes to engine performance with adjusting the idle screw your issue likely lies in the carb with a clogged jet or clogged port.

 

Have you had it apart and cleaned it?

A lean mixture will make the engine run hot. Use the troubleshooting section of the engine manual. Good Luck, Rick

I had it apart and blew air through all the ports a while ago and it starts and runs fine which is confusing to me but there is a good possibility i missed something.

 

does anyone know if the carbs and guts are the same between a 17 and 19?

how sloppy is that throttle shaft? if it wobbles in there that can add extra unwanted air into the mixture.

it is actually fixable, I have had many Kohler carbs bushed.

The kt 17 and kt19 should be the same

as mentioned above air getting in will also affect operation

Kohler does sell shaft and bushing kits if you find you you have alot of slop
