Barry, i would have to agree, yes, you do have sufficient air flow

fliggyg, just follow the instructions and you can't go wrong. If your tailheavy and can't move stuff around then at that point you can move the engine forward. If nose heavy, you have the option to move it back closer to the firewall or put the battery in the tail. For now, continue the march and deal with what comes when it comes. The reason I mentioned the cowl is that I am a perfectionist and 'thats good enough' dosen't happen in this shop. Well, I guess thats my problem. The directions are good and has put many of these in the air. You will do fine. Joe
