Carb, Tillotson, Air Balanced

[LAV]

Anyone have a problem getting a new Carb, Tillotson, Air Balanced to run? I had to make a lot of adjustments to the float level to get to run when I first got it. I bent the float and used shims. After a few days of running well it stop and I have had problems since. My fuel is clean. Ive had to set the float level to 1.3” to stop leaking. I can get it to run periodically but when it does it rough. Nothing I do adjusting makes much difference. Could use some suggestions, Thanks.
