after a few weeks of sitting i thought i would go and have some fun and run my gst in the park today. i did what i normaly do. right from the start it started to puttter and bog down i had it on full throttle and it wasn't runing the way it used to run it would pick up and then slow down. like 5 mins running it just died out and i then tried to start it again and it wasn't starting up. first the engine was hot and smoking. also i checked the glow plug and it was popped so i put another one in and it ran for a couple of mins as well but also bogging down on full throttle. i also hear a noise comming from the engine when it cuts off like a pop dont know if that is normal . i then procceded to look over the truk and i noticed that the clutch gear was lose (the small gear next to the covered transmission. i can slide it back and forth alittle bit but i dont know it thats normal cause the one behinde is tight and dont slide. also other question is that the carb arm wansn't all the way on the engine so i slide that back on maybe thats why it was boggin down. as for my qeustion is that why is it i have my radio set up on all 0 and when the car gets started it wants to move so i am tring to fix that also. need help.
