Can anyone help me. I have an 85 F250 with a Holley 4brl.I have these numbers on the horn
E5HE-9510-FA
List 50252
0035
this doesn't match up with anything I can find in the"Haynes Holley Carburetor Manual"
Does anyone know anything about this carb, is it worth a rebuild? I would like to put off investing in a new one for a while, other projects planned.
The choke looks like it's pinned, do I need to drill it out before adjusting? If I have to renove it I might as well rebuild it.I'm a little rusty but I think I can handle it.
Any other manuals I should be looking at?
Can anyone help me with an adjustment procedure I've read a message detailing adjustment using a vacuum gauge that sounded good but I can't find now that I need it.
This carb is probably a 4180EC (electric choke? emissions carb?). Built Jan. 3, 1985. The "H" in the 3rd location of the part no. is "supposed" to indicate a Holman-Moody Hi-po model, but we've seen at least 3 of these on this forum already. This might indicate that the "H" signifies a much more mundane application. Truck models typically have a two-stage power valve, an oddity which I believe is associated solely with this carb.
The rebuild kit for this model is typically $45-$60, much more than one for a run-of-the-mill Holley. Fuel and air bleeds are also more numerous, complicated, and difficult to get to. I've got one on my truck and I'm looking for a generic Holley to take its place. Rebuilding and tuning a Holley is supposed to be simple and cheap, neither of which applies to the 4180EC. However, they can be made to perform quite well--go to the carbedmustang board and search for 4180EC for a lot more discussion.
