Default RE: converted Stihl engine - how the heck do I start it!??

Thanks for the quality help guys! ...at least it's up to teasing me now. To make sure I have the details right, attached is a 4 point plan diagram to get it started.

I checked the spark last night, and there is one. This morning I followed all the details above, including prop position and flick technique. It didn't give me any flicking joy. Because it was handy, I got all evil and squirted some engine start fluid down the carb... few flicks and she banged out a few RPM's and then stopped. With the start fluid, ignition was reliable within a few flicks, but it quickly dies. Once it looked like it was going to pick up and keep it, but it died too. But it's certainly fired through more than a dozen strokes in succession... the usual teasing that motors do that are almost happy.

What's the throttle/starting position for cold motors?... should I let it sit in the sun all day and let the black anodized head get all hot?... do I have the fuel line correct in the diagram?...
Anything bad about using the starting fluid?...


In answer to the questions above:
*) where's my tech support?... this motor is an ebay special. the guy said it had run in testing for all of 15 minutes.
*) who converted it?... no idea, but it was certainly spiffy and professional enough looking job to have me pony up the cash.
*) do you have anyone who flys gas that lives around you?... it's possible, yet I'm in the middle of nowhere PA so anyone would be some amounts of driving involved. I'm a 30yo Australian that's been flying RC since he was 6, somehow stuck in central PA ...I've watched a ton of guys play with petrol motors, but not in such a way that I know how they tick.
