ABSTRACT:
A vacuum advance regulator designed to control the suction force of the vacuum that is applied to the vacuum advancer. The suction, in turn, controls the spark timing and allows combustion to occur when the crank position is at 12 degrees at the ATDC, thus, producing maximum engine power efficiency. The regulator consists of a body (1) containing in part, a vacuum chamber (2) that is connected to the outside of the body by a pair of nipples (3) that are inserted through a first bore (4) and a second bore (4'). The other side of the nipples are connected to a vacuum hose (11). One side of this hose is connected to the vacuum advancer while the other side is connected to the carburetor. The vacuum advance regulator also includes a pair of parallel adjustable throttles (5) and (5') that are in-line with the vacuum chamber (2). The two adjustable throttles provide the adjustment means that allows the vacuum force to set the spark timing.
