Could be a couple of things.
Check the needle and seat for debris. Change the O ring on the needle and seat with a correct o ring.
If the carb sat, and dried up with old fuel, that could be an issue.
If the car sat a long time, crap from the fuel tank and lines could be creating issues.
You would see fuel dripping from the boosters (front or rear), with any of those issues.
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!
