I've got a holly 1904 for a 1967 196 engine that needs to be rebuilt. Is mr. Mayben accepting rebuild jobs?

He's not back yet fred. I believe mayben should be back up and running by this time next month but I cannot guarantee it.

Thanks Jeff....I've got the 1904 from a 196 at m
y carb guy's shop right now and hopefully he'll have it done soon. In the meantime I've got a 1904 from I think a Ford on the 196 engine. This carb has the choke lever reversed so I had bring the choke cable in from the front of the carb. The carb seemed to work ok, car started and idled, some acceleration issues, but over all did ok.
It started running rough and now I cannot get the thing started at all. Checked the plugs and they are wet with gas.....changed out the main jet to a 67 from a 70, but still no start. The engine tries to start but will not actually run.
Can anyone tell me what the main jet size should be on the 1904 for a 196? Also, what is the range of the settings for the idle mixture screw (currently set at about 1 1/2 turns out)?

May be a float issue! I do have a super filter, so crud in the line is unlikely, but possible. I'm trying to get a fix on the "float level" angle to shut off the inflow. I understand it should be about level while the car is running. But I don't have a glass bowl and "running" ain't happening...so anyone got a idea of the shut off angle of the float while static?
This ain't the exact specification but it will get you in the ballpark.
Float level setting with the carb body(fuel bowl ) inverted: from float toe to top of bowl is 13/64"
as it sits on the engine, you can measure the fuel level in the bowl by removing the economizer valve diaphragm and sticking one of those narrow rulers in. The fuel depth(wet) should be close to 11/16"
these should get you started. Remember though a carburetor for a Ford is different than one for ihc. There is a whole different calibration involved for air bleeds, idle circuit size and emulsion orifices that will make or break how well a carb plays with an engine for drivability and mileage.
Fatter jets won't help at this point. Main jet for a 196 is a #67. Try 1 to 1.5 turns out for idle screw setting.
