Wonder why those carb screws are so hard to get out?

[HemiKat]

This may be a repost but Ive never heard of it before. Apparently the phillip head screws in the Carbs are different than normal phillip heads.

Anyoe else know this?

The reason I quickly replace all of them with stainless hex heads anytime a tear into a set of carbs...

too many headaches from those little star ba$tards.

My ivans jet kit came with them, I guess they know better too.

I've found sometimes I can sneak a little pair of channel locks I have on the screw head and crack em loose. That way the head doesn't get stripped.

+2, always replace with hex cap screws. I hate getting the phillips out, but at least I only have to get them out one time.....

impact driver to get them out might work. $20 or so @ sears

JIS screws are common on Japanese bikes. The screwdrivers for them are easily bought online and are not expensive.

Yes, we've been talking about JIS screws for years. I'm still trying to find an economical source for drivers.

I've got an impact driver, and probably two dozen types of Phillips bits.

What I don't have, are JIS bits... http://www.rjrcooltools.com/vessel.cfm

kramiton, you are a braver man than I. I would never use impact driver on a little carb. If, say a man did such a thing, a re-sync would be mandatory. Maybe you wouldn't either and I misunderstood...

A bike mechanic that seems to know his stuff told me that even if you are rough getting the carbs into or out of the bike, a re-sync is usually required because of the flex of the assembly of all 4 together.

As for impact tools, I have a Snap-on air hammer, with a Snap-on driver that goes into the air hammer with bits. So, picture an air hammer with a philips screwdriver sicking out the end with a handle to turn it. It works like a charm. Just a little rattle and a twist of the wrist takes out all phillips screws.

That said, I never use it on carbs.

I ALWAYS use the impact when opening the carbs for the first time.

Then replace with with hex heads.

I found I had good luck with a 1/4 drive socket, a good phillips head bit and a long extension. I put the carb on the ground (piece of carpet under it) and leaned into the handle. They broke free really easily.

+1.

And if you're doing carb work, you should probably be syncing them anyway, so no harm done.

What kind of impact driver are you guys using? I have a driver that I think is turned directly by the hammer blow (takes a pretty good hit to turn it), and I wouldn't use that.

But I think I've also seen an impact screwdriver that just required you to push on it hard (compressing a spring but not turning the driver), and once it reached a certain threshold it would release all that spring energy with an impact. I don't have one these, but I would use it if I did.

That's the one.....

I take all the black caps off, pull the slides, and set the carbs upside down on a piece of carpet. I've never damaged anything.
