1.) I use Omega branded fuel which uses a blend of synthetic and castor oil. I also get the cheaper 5% nitromethane content fuel as well. Depending on the compression, you could run zero nitro fuel too. many engines run well off of zero nitro glow fuel. They just have a more sensitive needle adjustment to them.
2.) Maybe, maybe not, but usually those bigger engines hand start quite easily. You can use a reverse flip method to start it, thus you are less likely to slice yourself on a razor sharp prop trailing edge.
3.) I normally run the engine extra rich, really rich for a few minutes at a lower throttle setting to ensure it gets oiled up good on the inside. Then go on to normal break in procedures. You might also want to check the valve gaps too and while the valve covers are of oil the top end some and dribble a little oil down the pushrod tubes for the lifters down below. The initial engine runs can destroy a glow plug due to minute metal particles and packing oils, so do not be surprised if the glow plug goes bad quickly.

Yeah the Fox Miracle plug works pretty good. Granted there are some other plugs that work good too and maybe arguably a little better, but they work fine.

After a while running it in do check the valve gaps, on a new engine they can change on you.
