Thanks!
Cgilbert,

If you can I would start with 37 or 40 mm chokes. This will give you a stronger signal and make it easier to tune the carbs.

However, as for a baseline I would start with

60 idle fuel
100 -120 airholder
50 bypass
4.5 pumpjet
----------------------

Do not worry about the main stack yet. get the idle circuit adjusted properly then move on to emulsion tube. This should get you up to 2000 rpm.

Next hurdle will be selecting you emulsion tube. What do you have on hand?
