For some reason, despite the fact that almost EVERYONE wants to use a 4-stroke for scale models, nearly all plans (and kits and ARFs) seem to be designed with a 2-stroke as the default. So you just have to get used to ALWAYS having to figure out the installation. It's just the price we pay for using the 4-strokes we love. But you do wish that designers would catch on!

Check out the Puppeteer thread. There is a lot of discussion about the mods needed for mounting a 4-stroke (which I think every single builder in that thread did). It wasn't that hard.
