ATC 70 Won't Rev Up

[badbronco]

My 1985 has a new carb on it from ebay, ran great for a month. Now it starts and idles great but when you give it throttle it dies. Plenty of fresh fuel. No matter how slight or aggressive I apply throttle it falls on its face and dies like its starving for fuel. What do I need to do?
Gas is clean as it has a new plastic tank on it.
Thanks

Sounds like the main jet is clogged . Are you running inline fuel filters ?

Agreed with shortline...pop the carb off and give it a good cleaning, a fresh spark plug, and make sure you air filter is clean and you should be good to go.

clean the main and PILOT jet... it will run like new again,,, and if your not using a fliter GET ONE ,,, when you clean the pilot jet look and see how small the opening is,,, thats why the filter...
