Carb screws torqued or not?

I have a factory service manual but don't see any specs on torque values for the carbs. When doing a rebuild, what do you do for torque settings (ie. the bowl screws, jets, hat screws)? I will do by feel if necessary but just checking to see what is the proper way?

 

German torque (goodentight) on the screws. Just snug on the jets.

 

No more than 1.3 ft-lbs, or 15.6 inch-lbs.

Do me a favor, lose the JIS (Japanese Industrial Standard) "philips" screws and change them out to allen head cap screws. SAE (Society of Automotive Engineers) philips screwdrivers don't fit them very well, and tend to "cam" out on screws that are stubborn.

If I remember, M5x 0.8mm x 8mm on the hats. Maybe 10mm where the brackets attach.

Then M5 x .8mm x 12mm on the bowls.

 

Or just get s JIS screwdriver and use it all over the bike. Best money I spent as it constantly gets screws loose that other gripe about all the time....

 

Trouble is, where the ham sandwich can we get JIS screwdrivers? None of the usual suspects carry them, and I am not in the habit of chasing down a Snap-On or MATCO truck.

Plus, the Stainless Steel Allen head screws look really cool!

 

Are you sure there isn't a torque spec chart in the front of the manual? Many manuals will not a list a specific torque for hardware, but there is a standard you can follow based on type material, thread size and pitch.

With that being said, I don't torque mine with a torque wrench either. I seat the screws or bolts, and I give them a little more turn after that. About maybe an 1/8 of a turn.

 

Chacal

 

Ah, of course! On my next order to him, I will add those to the list!

I just don't understand why we can't buy them from Sears, Harbor Freight, AutoZone, O'Reilly's, Advanced Auto Parts or NAPA?

Oh well,

 

I think its a conspiracy between the fastener manufactures and the tool ones. When you strip enough screws, eventually you ruin the driver. Then you have to buy more of each...

 

I've purchased those 20 something piece screwdriver sets from Sears before, and one or two of those philips work just fine on the Japanese screws. They look like they would be too small, just about a step down from the standard phillips head, but they fit almost perfectly.

 

Yeah, I have used my #2, #3 and #1 SAE philips drivers, and you are right, they do work most of the time.

But when I really need them to work, they "cam" out, ruin the JIS philips head and now I am "miffed."

Every vehicle I own is Japanese, so having JIS screwdrivers would be the way to go, ideally.
