such a cam needs 20 to 26deg idle timing at minimum. Often, if it is a tight LSA cam 106-108 LSA
locked out timing is best. At any rate it will want a lot of idle timing. requiring a short limited 10deg mech adv curve or simply locked out.
A stock converter will not work.
anything else you want to remember and share about the details?
Cam card specs....grind number part number.... more...

The 600 carb will need tuning starting with correct positon of the pri and sec throtles at idle.
( the generous idle timing allows this) remove the carb flip it over and look at and reset the pri and sec throttle position for
correct idle fuel T slot exposure.
and a 4.5" power valve swap to keep a clean idle.

jetting 65 to 68 pri 4.5" power valve .028" to .031" shooter.. #75 to 77 sec jet or a #21 sec metering plate.
