Get it to idle first. If youre sure you dont have anything else wrong, and the reedcage is good, and you dont have any airleaks, and the engine is mechanically sound, then proceed to jet.
Get the pilot dialed. 1.5-2 turns out when warm to idle. You SHOULD have to choke it if the engine is cold to get it to start. If you have to turn it all the way in to get it to idle, youre too lean and need to go up a pilot size. If you have to turn it all the way out to get it to idle, youre too rich and need to go down a pilot size.
Get it idling nicely and then set the main. Put in a main that bogs when you go WOT, (keep going up in main till it does this), then start pulling back size at a time until you can go WOT without it bogging. Now youre in plug chop territory. Do some WOT plug chops and make sure your main is where you want it.
Once youve set the main, then you figure out driveability. Thats done with the needle. When you rev it, the engine sould pick up crisply and not rev too high too fast, just a nice steady wind up and a good healthy exhaust note. If it revs up too fast, youre lean and your needle needs to go down on the clip (which pulls the needle farther away from the jet so more fuel flows through the main on transition), if it picks up slowly and it bogs, go up on the clip which will put your needle farther down into the main restricting the flow of fuel to lean it out so youre not too rich on transition.
Hope this helps.
