| i have a 1971 super with a solex pict 34 4 carb in it? what engine should that be out of? also i replaced the dist. yesterday, i have an 009 now, but the one i took out wasnt a stock one, it was kinda weird, it didnt really have points like a normal one, but it had like a rotating disc with little magnets and a sensor underneath that. anyone know what kind that is? i think it had 049 on the back... |

| I believe the 1600's had the 34 pict's on them. The other distibutor had been changed to electronic ignition. This eliminates the need for points. |

There's a chart of original jet sizes on Bentley page 20. Looking through the 34pict series, the only one that has a substantially smaller main than the others is the 34pict-3 for California 1972-1973, which has 112.5, the rest are either 127.5 or 130. It lists the 34pict-4 as the California carb for 1974 (which makes it a one-year part, I guess, since they all went to FI in 1975, right?) and lists the default main jet as 127.5.
The main difference between the 34pict-4 and the much more common (then and now) 34pict-3 is is the accelerator pump. The accelerator pump parts are different, and there's a key additional part. The 34pict-4 has a thermostatic valve that INCREASES the accelerator pump volume when the carb body is below a certain temperature. That gives more gas through the accelerator pump when the carb is cold, less when it's warm. |

That chart in the Bentley is not very accurate. Try this one I put together instead, it's MS Word doc file:
