2 Stroke Ds80

Hey there, having some troubles with a 95' ds80. Crab needed a clean, took it off, re installed properly, and when I kick it over, it will idle great, then out of nowhere, the idle will jack itself up way to high. Has clean gas, needle is seated properly inside carb. Any idea? Thanks
 
DS 80 is a solid back yard truckster. Here’s what I experienced in the past.
Ripped, torn or cracked carb boot. Sometimes the hose clamp is just garbage.
The base gasket: it’s a 1 use crush type gasket. You can’t reuse it. People sometimes reuse it and get away with it for 6 months. Same goes for cylinder base bolts. People tighten them and don’t torque or they don’t retorque after initial warm up.
Head gasket is the same. Don’t reuse, check torque.
Oil injector. Make sure it’s not loose or has a torn gasket.
