i have a thunder tiger 46 in my kadet. i seem to be having a problem when it is at idle speed. it will run for around 10 seconds then die off. i have to use my radio to increase the sub trim in order to keep it running. know the problem is when im landing i have to decrease the trim to slow the motor down enough to land and am taking a chance of the motor quiting on me.now this motor isnt the same as my other OS motor which has a low end needle vavle which is used when the engine is at idle. i looked my motor and cannot find any thing to adjust. i did notice a bolt on the back of the carb facing the block but that is a tight space for an adjuster. so if any one can help me that would be great.
