Re: New here.
You might need to adjust that cable the other way. You might have too much slack in it now. Or the idle screw set wrong.
Remember when trouble shooting start at the last thing you did.
If that is all okay, then look for air leaks. Remember you have been running it fuel heavy now that you have that down, you might have had an air leak all along that made it balanced now it is out of balance. Look at your manifold tube as a possible source of an air leak. It is by far the most likely. With your choke set at about half it should start in just a few yards. I always stop mine when it starts then warm it up enough to turn the choke off completely before I take off the first time. After the first time it usually isn't necessary to choke it again.
