Re: 87 Bayliner with 2.3L choke problem
The choke is not "vacuum" is is called a heat stove choke.. there should be pipes or fittings that come out of the choke, that attach to pipes that are installed in the manifold.. These pipes circulate warm air thru the choke housing and cause a heat sensitive spring to contract or expand, which in turn, moves a lever to open or close the choke blade...
If your carb was originally not fitted for this type of choke, it normally would require you to change out the manifold in order to use it.. Based on the design of the 2.3 intake.. I don't think they ever used this type of choke on an OMC application
If you have the original choke from the original carb, you may be able to use the choke again on the new carb.. again, my concern is whether or not, they installed heat stove chokes on marine applications, and if they did not, is the carb you purchased a marine carb or the proper carb for a 2.3L - I think it is not... the manifold design on a 2.3L should not allow for this type of choke
