Thanks Mike, hope so too... As far as any other name it goes by, you got me.. They just said it was a spring that was broken which controls the butterfly which I assume is the same as the choke (?)

Yep choke plate is sometimes refered to as butterfly. In the base of the carb are the throttle plates which control the amount of air the carb allows into the engine and is controlled by the throttle cable.

The choke element is a coiled bi-metal spring that heats up and unwinds a bit. It is connected to a rod that then open the choke plate. The choke plate should also be free so that when the throttle plate opens wide the engine vacumn will actaully cause the choke plate to open even if the spring has not yet fully heated up.

6/2014 Update: A Brewer Shipyard mech finally "adjusted" the carb for a 2nd time, idles but the idle was set to 1,000 rpm in error based on what I've read which should be @ 650 like its twin. How they thought it was ok to have so out of synch is beyond me, but par for their course this far.. So I lowered idle, but problems still exist that Brewer claims was fine when tested:
Problems are as follows:
1) hard start req'ring rpms above 2K until fully warmed or stalls repeatedly
2) bogs down & wants to stall when throttled up slowly or quickly in either neutral or in gear. Hear air/sucking sound as it bogs.
3) when throttle is pulled back as it is bogging to prevent stall, the rpms then jump way up to where the throttle was just prior even tho its back to idle position.
4) upper rpm range is totally fine & runs strong thru 3K's
Anyone have this issue or know of an easy fix, ie fuel/air mix etc??
