Jason, a few things to check. First, make sure you are running with muffler pressure. Also check that the tank is not too low. As has already been suggested, make sure that the high speed needle is at the correct position. Normally, you should not have to change the low speed needle on a new OS, but if you're having trouble, check that too. Remember to count the turns as you close the needle, so you can compare what you tried to the OS recommendations.

Also, check that you are getting good power from your glow starter. I used to use glow starters, but found that they made it much more difficult to hand start. Personally, I think glow starters were invented as a way to sell more electric starters. I've been using a power panel driver for years, and NEVER have trouble getting an engine to fire. If I didn't have boats, I probably would not even own an electric starter.

I'm not so sure about starting with the throttle wide open, that's never worked for me. I always start my engines with the carb at an idle setting. Be sure you get a good prime. To start my engines I open the throttle, put my finger over the carb and flip the prop a few times, BEFORE ATTACHING GLOW POWER. After this I set the throttle to idle, attach the glow power and start it up. It's rare that I need more than 2-3 flips to get it running.

And finally, any chance you can find some airplane, instead of car, people? You're going to have lots of other questions, it's best to find someone to help you soon.
