Separating carbs

[icerigger]

Didn't want to do this, but after setting the valves, replacing the alternator rotor and regulator and putting new tires on the Behemoth, the first fire up didn't go well.

I must have disturbed the carbs somehow because, when I turned on the fuel, all of the cross tubes started leaking. So I bit the bullet and pulled the carbs and separated them to replace the O-rings. BTW, if you're doing this, you only need to remove the choke valves on carbs 1 & 4 (OR 2&3), at least on the '79 & up. Figured this out after I had them apart.

Got the O-rings in and the bank reassembled, but the FSM says to toss  the choke valve screws and replace with bolts and double retaining washer. Is this really necessary? I was just going to reuse the screws with some red locktite. Am I likely to have problems from vibration or gas dissolving the locktite or something else I haven't thought about?

Heres a good link for carb rebuilding.

Looks like he just uses new screws.

Just reuse the screws. I have never had any problems reusing them.

I replaced screws holding the bowls and tops on that were stripped, but I reused everything else and I haven't had any issues.

Gasoline will not harm Loctite, however, use the blue, not the red. The red is designed to be removed only after the application of heat (500 degrees according to their website) In reality, I've found you can remove fasteners with red loctite on them with hand tools, but the red will require much more torque you to get them out....not good for small screws like on the carbs. The blue is designed to hold, but to be removable with hand tools.
The general rule we used when selecting them for auto racing was, blue for anything you may need to periodically service, red for anything that will likely be in place until the next major rebuild.
