Was there a problem using the old carb ?

If you choke the heck out of it does the carb throat get wet ?

Ooops, somehow I missed #10. I doubt the problem is float level but its easy to check and adjust. It should set level which should be 1". Adjusting is by bending the float arm carefully.
Tilly's like more GAV opening than Zenith's. Try starting at 1 turn. Idle mix should be as Purdy says, 1.5 turns to start out before adjusting.
