I have an Ofna MBX Pro with an 8 port Hyper 7 Sport. It runs great when I first start it. Starts within 5 seconds and it is dialed in to run at 230 degrees. But when I try to start it after a run it won't fire. It sounds bogged down but I have made sure it is not flooded. I tried to fire but when I give it even a little throttle it bogs. I changed the plug and the fuel lines. I am running 30% Nitro.

I have called a couple LHS and they have no clue. Any ideas would be graetly appreciated. Thank you.
