Anyone know the recommended float setting for Holley 1850 with non-external adjustable float bowls? I noticed my front carb (lead carb) is weeping into the intake on the primary throats when I shut it off hot. I have insulator gaskets under the carbs and the float bowl temperatures were around 116 degrees at shut down so I suspected the float setting is a little high in the primary bowl.
In this photo the right bowl is the primary and the left is the secondary. On the primary I can insert a 5/16 inch bit under the outside end of the bowl before the end curve. On the secondary I can insert a 3/8 inch bit. So the primary end float setting is higher which goes along with my theory.
I've Googled a lot and can not find any rebuild instructions for non-adjustable bowl 1850 carbs. I found some internet threads that suggested that with the bowl inverted, the top of the float should be approximately level or slightly higher (lower when right side up). Anyone know the Holley spec?
If I can't come up with anything I will probably adjust the primary side to match the secondary side since it is dry - of course it doesn't have an idle circuit.
