Hi, all,

I have been browsing the forums for a while and registered today because I need your help.

I have a direct drive KT100 which is able to start on the stand but it does not start when putting it on the ground and push starting it.
Carb settings are 1.25 turns for Low Speed and 0.5 turn for High Speed, oil/fuel ratio is 16:1 of AMSOIL DOMINATOR 2-Stroke Racing Oil.
The engine has a new spark plug (Autolite AR51), air filter, new fuel filter and hose and carb has been just rebuilt meaning changing the gaskets and all that.
When push starting the kart there are times on which it will try to start but there is no throttle response so, at the most the kart will move 10-20 metes and stall.
I'd greatly appreciate any insight that you may provide to troubleshoot this issue, thanks.
 
Id try 1.5 low and 1.5 hi .
What gear ratio like a 9-80 ?
Adjust the carb after ya get moving......

Edit : follow the advice in posts #3 and #4 .

When starting a dd Yamaha, the high speed jet should be turned off, and the low speed open no more than 1 turn. Just *ease* into the throttle a bit once it fires and you jump in. At that point, open up the low speed to your track setting, and then do the same on the high speed and you should be good to to.

Also, when you are coming off the track and coasting down to come to a stop, shut off the high speed, then shut off the low speed and the engine will die as you coast to a stop. Doing this make it WAY easier to get it started the next time.

If this doesn't work perfectly for you, then time to dig into the carb and make sure it's set up correctly.
