Hey I recently got a 1978 suzuki ts125 and it ran well until this week. It was raining when I was riding it and it began revving realy high but whenever I let the throttle go it would stall. I checked the reeds and they were fine, and the carburator is new, same with the spark plug so I don't know what could be happening. The response is very delayed on the throttle when it does run. The bike is also very hard to kick start again after stalling, I don't know if that's related.
