I’m in need of new screwdrivers so thought I did give the JIS drivers a go. Anyone’s here use them? I believe they may be better suited to the standard fasteners found on our machines.

In particular this Vessel megadora set on eBay is tempting. Any thoughts? https://www.ebay.co.uk/itm/Vessel-Megadora-900-P1x75-P2x100-P2x150-JIS-Cross-Point-Screwdriver-Set-Japan/253240046857?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

You only need the .150 one.
They are 100% worth the money because they ARE the correct tool for the fasteners unlike pz and philips screwdrivers.

I've personally got the Vessel .150 it's my go to tool

do you not need the P1 for the smaller fasteners on the carbs for example?

Not sure which you mean by the smaller fasteners in the carbs but I've just removed one of the screws holding the throttle butterfly in place without a problem

Here's some info on JIS screws:

I am usually using 1/4" bits with a screwdriver handle, ratchet or the  impact screwdriver I recently got (very useful).

I was referring to the various assembly’s bolts /screws for the carbs. Was just guessing that they would take a smaller driver. I did take them apart a while ago, unfortunately too long ago to remember what tools I used.

You're very welcome Cool

If you read the armchairbiker link in the E10 petrol discussion, he said

"I bit the bullet, cursed my perpetual failure to buy JIS screwdrivers and opened the carbs."

So there will be no cursing when tackling your carbs  Very Happy

+1 for JIS screwdrivers. The fit is so much better. 
I got the Bessel-(Vessel) interchangeable type. I normally hate interchangeable screwdriver nonsense but that tool is genuinely brilliant. 
The p2 and the flat head on are the same shank. Very handy. The flat also has no taper so it sits right down into a slot head. Good for pilot jets etc.

I got the three, #2 is the most useful but I use the #3 where it fits in big screws and it removes/tightens without any of the damage associated with using Philips drivers. I think that Japanese screws got such a bad reputation for being soft because in the 60s nobody had JIS drivers and used Philips #2 points which butchered the screw heads! A Philips #3 works fine but who has one of them?
I even bought the silver impact pair though I've yet to need them!
Buy good tools once, buy bad tools twice!

These are good, I have the number two point and it's more comfortable than the blue ones also you can apply more pressure with it.

Just to jump on the JIS bandwagon, I have had the set of 3 linked in the original post for years and can confirm they make more of a difference compared to a 'normal' screwdriver than you would ever think they could by looking at them! They have saved me from cutting/grinding out many screw heads!

Never knew this. Mucho interesting!

Edit: Bought one to se if it was any good. It was! Actually, it's one of those things you'd think was 'obvious', but reality is different. Still; comes highly recommended. And as with most things japanese, the manufacturing quality is - well, if only everything was made this well...
