I agree that carb is fine for your combo. I also agree with "Cudajon" as the secondary air door adjustment is very important on the AVS. If it opens to soon it may stumble and hesitate. Its important to have the air valve spring tension right so it opens at the right time. Many carbs also use the choke pull-off to slow down the air valve opening so its not to fast and dont bog down. But I dont think the AVS uses the choke pull-off to work with its air valve. Ron
