Finally returned to the project
Well last night I removed the .46, found out that carb body was split and leaking air. I was going to put the new TT .61 Pro on it without any mods but that just isn't happening. I cut the nose off about 1/2" away from the firewall and have been sanding down to it. I plan on using a plywood doubler to create a nbew extension to the firewall. Another modification that I have done isto create a hatch to the fuel tank area, so I can re-work tank and also reach the blind nuts for removal and installation.
I will post pics later this week if at all possible. Anyoe out there have a y experiences with putting an oversized engine on one of these? Anything to watch for other then COG and firewall beefing???
