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