Carburetor Torque specs?(how tight?)

[1_v8_merc]

Bike is a 82 gs650g
----

How much should I tighten the Outer carburetor screws?
(8 screws per carb, 4 bottom, 4 top)

I've got 8mm's for the tops, and Phillips for the bottoms, all are converted to steel, all have washers too.

I have 2 seperate torque wrenches(one in Inch Lbs. and one in Ft. Lbs.)

I just have NO IDEA how tight to put these screws!

I thought I saw a post on here before about this, but couldn't find it.

I also have the shop manual, but couldn't find it in there either.

I thought I recalled someone one here saying, to just tighten them snug, and then give them alittle more turn.

It seems too simple to me, I just dont want fuel leaks,

I don't even torque mine (don't have a wrench that will go that low). Kind of like spark plugs. Finger tight, then maybe 1/4 turn or so.

Snug them down, let's not make this too difficult.

Originally, these were philips screws which I don't think have a torque value, per se. If you tried to tighten them too much, the screwdriver would start to slip out of slot (cross).

Kudos for replacing, but remember the only task of these is to seal top at diaphragm slide and the bottom at the float bowl gasket, both of these are not under any pressure. Just make sure the bolts will not come loose with vibration.

Alright thanks guys, that's what I thought.

That's just me being paranoid again, I'm used to working on modern fuel injected vehicles, so this carb stuff is a little new to me.

I'll just tighten them down snug, then 1/4 or so.

Easy enough for me.

waterman- yea, i originally had brass screws on there(arent they a combo of brass and steel?). But anyways, I fought with those for a few nights, until I developed my own technique to getting them off. That would be the last time this bike ever sees brass again! Im trying to convert anything I can to accept sockets, it's just a lot easier for me that way.

Oh well, whatever holds them down I guess!

You could always look up the torque spec. for the bolt grade and size...

Just sayin'

Use a small handled allen key and snug down the screws. Don't use a long handled wrench and try to do anything regimented like snug + 1/4, you may stripp something. You need to develop some feel for things like this.

Better way to say it. "snug". All that's needed.
