hey guys, i am needing some help here with my 83 atc 70. it has no pull start so it has to be push started lol. i can push it with about 1/4 throttle and it will start and run for 5 seconds or so and then die. soon as i start pushing it again it will fire right off with 1/4 throttle, any more it wont run and any less it wont run. i have been thru the carb 4 or 5 times with no luck. i have tried a new spark plug (NGKC7HSA) and it didnt change anything. the choke seems to be not working correctly but it shouldnt keep it from atleast running for more than 5 seconds? I think it might just be time for a new or good carb. does anyone have one they want to sell? also i need a good gas tank that doesnt leak.
