And just in case you're as stupid as me, you can use the compressed air in a spray can. Buy some at a computer store.

Something is still not right in the pilot circuit or there is still a vacuum leak somewhere. Either the pilot circuit is clogged requiring the screws to be all the way out to provide enough fuel or additional air is being introduced somewhere, again requiring the pilot screws to be all the way out to provide enough fuel. I know it's a PIA but a good cleaning of all the orifices/circuits as Dave points out with a good carb cleaner (I use Castle Dragon's Breath) and compressed air is the best place to start.

After I put the correct plugs in it and played with the pilot screws it runs great. Any Ideas on why the pilot screws needed to be turned out so much? Ben
