Quick question

Yes, I do that too, along with penetrating oil and heat. Sometimes you need to go "the whole nine yards" to get those buggers out, lol. I also custom grind insert bits for a perfect fit in the jet slot. The bit at left center hasn't been ground and as you can see, it isn't a very good fit .....

One thing that pic above reminds me is it's important to use flat bits as shown. Regular flat blade screwdrivers with their wedge shaped sides are dangerous to slots and asking for trouble. Also use the maximum width that will fit down the hole
 
Has anyone ever tried one of these "shake and break" attachments for an air hammer? Basically, you mount the RH end in your air hammer and the bit in the LH end - and then hit the trigger while using the red handle to turn the fastener.

Obviously this would be much too violent for a carburetor, but for some frame and suspension fasteners, it could be just the ticket.

One of my favourite YouTube channels "South Main Auto" uses this tool quite often and it has never failed to loosen a stubborn/rusted/corroded fastener yet.

With all due respect 5Twins, NOOOOOOO....NOOOOO.....they're not #3 Phillips - they are #3 Japan Industrial Standard (JIS) screws - as are everything else on every Japanese-built car, bike, VCR, toaster...etc.

It may not seem like a big deal - but note how the JIS screw in middle of 5Twin's photo of five clutch basket screws is all chowdered - that is because someone used a Phillips driver on it. In fact, if you look carefully, the heads of nearly all of the cross-head screws on nearly all Japanese bikes are chowdered - and that is because nearly everyone used Phillips drivers on them all these years.

PLEASE BELIEVE me when I tell you that using a JIS driver is much more effective and you will stop damaging the screws.

If you use a Vessel IMPACTA #3 impact drive (see photo below - the #3 IMPACTA is the big silver handled lad second from the right) - those clutch screws will be off quicker than a bride's nighty.

You can get a full set of very high quality "Vessel" brand JIS drivers on the interweb for not much money or you can order an equally nice set from www.gofastinnovations.com and either set will look very fetching in your tool box.

The only wrinkle is that gofastinnovations.com does not offer an impact driver like the silver-handled Vessel IMPACTA - but rather they offer a set of bits that can be used in an impact driver (and these work fine too - if you have the correct impact driver handle).

Oh dear me - am I becoming obsessed with this issue?

I bought a set including the impact Don't use them all the time
But your right a phillips will bugger out all those screws
Cause I used to bugger them up until I found out here
 
Pete, I have something along that line in my aircraft sheetmetal toolbox. Also used them during my phased aircraft times when I was much younger. That and/or the "Johnson Bar" got the really stuck screws out. If either one failed, Sheetmetal shop was called to drill the screws out.

While we're at it, the Craftsman finger bit holder pictured in 5twins post is perfect for adjusting mixture screws on bs34s. I draw a line across the top and down the side. Makes it easy to measure rotation in cramped quarters .
 
I've used a 2-step process to cope with cross-point screws.
1) Remove the fastener by gripping a hexagonal driver bit in a drill-press chuck. bearing down on the drill feed lever and backing the chuck out by hand.
2) Replace the fastener by throwing it away away and using an Allen screw instead.
