Re: Leaking carb

if its a 4-5 carb the lean rich lever and shaft are way above the bowl dont see how it could leak there and still run cause the bowl would have to be over flowing with fuel to leak above it if the lean rich is in the bottom of the bowl then ya have a 6AA carb and the o ring has failed...easy fix

Re: 0540 Straight Magnetos.

putting an impulse coupling assy and stop pin on one of the mags would be much cheaper and more reliable for air boat use and greatly simplify your ignition

Re: lycoming 200 wide deck

no i'm not saying that at all...if the 6AA is as it was in the helicopter with the AMC unit still intact then it is a lot of carb for a 4 cyl but any of these carbs to a certain point can be modified and setup to run on different engines...if ya find your using a lot of fuel for a 4 cyl or the plugs...
