Hi RD,
The first thing I would ask (since you live pretty far north), is what is the outside temperature when you tried to get the Fox started?
The second question would be when did you buy your fuel? Hopefully, not when you bought the engine!
Third question is what kind of fuel, and what size prop are you using?
If your Fox engine is still new, and has only run a few primes, you can expect it to be hard to start. That will improve with a proper breakin, on the proper fuel. If you are not sure how to breakin a Fox 35, you should do a forum search for "Fox 35 breakin", and read that.
Generally speaking, Fox engines need lots of Castor oil in the fuel for breakin. You can NOT use R/C fuel!
Sig and Fox sell the proper fuel, but you may be able to add Castor oil to what is available locally.
OK, you know that it runs a prime, so you are most of the way to a successful engine run!
When you say the spray bar is clear, does that mean it draws fuel when you cover the venturi with a finger, and flip the prop over several times? If it does draw fuel all the way to the spraybar, without a bunch of bubbles in the fuel line, it probably doesn't leak much air into the case.
Let us know more, and we may be able to help.
