i just bought myself a 1972 ford maverick 200ci I6, and it's running fairly rich, how would i adjust this? also it stalls at idle(in park), and if it doesn't stall in park when i put it in gear it will stall due to the load on the engine, do i need to increase the idle speed? or is this due to the engine running to rich? by the way it is cold and wet out, it has a new distributor and plug wires on it
The 1972 6 cylinder uses a curb idle solenoid to keep the engine idling in gear. If it is running rich then you need to at least adjust the float level and probably need to rebuild the carb. If the curb idle solenoid is not there then you may have to find one in a wrecking yard or you could convert to a pre-1970 carb (buy a rebuilt or get a new one) because before 1970 the carb was setup to rune without considerations for emmission controls and "lean burn" technology that was in its infancy in 1972. You could also convert to the latest 200 I-6 carb when they had sorted out the mess with emissions. I vote for the non-emission carb because they always work better. I don't have to take mine through emission test though so that may be a consideration for you. Paul
Random Hero, I bought a kit for my Sprint's carb. (D20FMA) and installed it over the Weekend. 14.00 at Auto Zone. Took about 2hrs, mostly to get the screws out (35 years of grime). The kit will have a tool that allows you to set the float. (A card board L with measurments on it). If the carb has never been apart then a kit will not hurt you at all. Just take your time and pay attention to how it comes apart. The instructions are not that great and memory will help you out when its time to go back together. Jerryfow2
