I am using Odonnell speed blend fuel and I think I just need to lean it more. I just have to lean it more each run. I can fire it up after preheating it and it feels good on bottom and top but midrange it just bogs. I lean it out some and it is fine for that tank refill and its back to the midrange bog.
