TROUBLESHOOTING Q&A

All technical information including videos assume parts used are our brand. Parts from other sources may not install, or function the same way. About the Autolite 1100 Carburetor

• The Autolite 1100 one-barrel carburetor was included on 170" & 200", 1963-69.
• 1963-1967 (some) came with a spark control valve.
• 1968 - The venturi size was changed to 1.10 and there was no control valve. The distributor was changed to use a mechanical advance instead of using the venturi vacuum previously.
• 1967-1969 - Two diaphragms were used. The added diaphragm is used as an anti stall dashpot. Only one diaphragm was used prior to 1967
• Correct venturi size for Mustangs was 1.10", or 1.20"
• When no tag is present, Identification can be done by inspecting the base. You can sometimes find a Ford part number there.

AFTERMARKET 1100 CARB VARIATIONS

Parker Brothers valve

The Parker Brothers valve consisted of an aluminum plunger with a concave trapezoidal shaped opening on the end facing the seat. A trapezoidal shaped neoprene disk was inserted into the concave opening. The trapezoidal valve would stay in the trapezoidal opening’ The seat orifice was surrounded by an inverted flare. The flat lower portion of the trapezoid sealed against the inverted flare. These valves had the benefit of much more consistent bowl levels, as full flow was available whenever the valve was off the flare (no point in the orifice). Also, as the plunger was produced from aluminum, it could not be magnetized. Unfortunately, these valves are no longer in production.
