Thanks live evil. That makes sense. I think my injection is working. I've replaced the crank seals today and will take it for a ride tomorrow to see if any changes. If its still dying, I'll revert back to a new 49cc setup.
I'm looking all around the internet for decently priced round main jets. It seems that I could buy 10 sizes that I don't need for about $8 or I can buy one size that could possibly need for $8. By my math, to troubleshoot main jetting I'll be spending about $25-$32.
