: How do I tell the difference between a Holly
: 1945 and a 1645? <FONT COLOR="ff0000"> You mean a 6145. The 6145 is used with the O2 feedback system. Usually only found on California slant 6 cars and trucks. If you have the O2 system you should find a O2 sensor in the exhaust manifold outlet on the rear side. The O2 carburetor will have about 4 wires coming from it, 2 going to the top of the carburetor (where the mixture control solenoid is located, and another 2 wires - one of which goes to the throttle kicker solenoid and the other to the curb idle ground switch. The 1945 carb will only have the 2 wires --- those going to the throttle kicker and the curb idle ground switch.</FONT>

The ESA computer controls the ignition timing (and fuel ratio if you have the O2 system) If the computer is disabled or has some of the sensors disconnected then the engine will only run with fixed spark advance and will have poor performance and fuel mileage. Has someone installed a distributor with mechanical and vacuuum advance???? And a ECU and wiring from a older vehicle?</FONT>

: Can I use a Carburetor from an earlier model? <FONT COLOR="ff0000"> I had a older carburetor on my 1987 truck for a while, worked OK. Only thing it did not have hookups for all the emmissins stuff and also the hole for the auto trans kickdown link was located a different distance from the throttle shaft and changed the ratio. </FONT>
