Thanks, my friends! T, this issue has been the biggest headache for me on this build and let this be a lesson for anyone building the Roden kit with the engine exposed: INSTALL THE ENGINE BEFORE ATTACHING THE NOSE ASSEMBLY TO THE FUSELAGE! I had gone to a great deal of effort detailing the Roden engine, replacing ignition wiring tubes, replacing valve springs with guitar string, adding spark plugs, adding rocker arms, adding wiring harnesses and oil and fuel plumbing, all with the intention of leaving the top cowling pieces off, only to discover that the engine would not fit past the firewall and the radiator. I then went to plan B, installing a Karaya engine, which is much smaller, and it, too, wouldn't fit without sawing off the front and rear of the crank case. I'm able to make it work, though the Karaya engine is nowhere near as detailed as plan A. Therefore, the only bit of engine you will see, will be the top and what can be seen through the open inspection panels. Disappointing, but it'll be alright. Working on all of that right now.
Cheers,
Bud
