Float Bowl Screws

a hand impact driver is your friend

Seriously?

Seriously?

I'm with Richie, no way I'd bring a hand impact driver to a stuck carb bowl screw fight. Worst case I vice-lock the suckers out, or drill.

yer suppose to use the hand impact before you bugger up the screw, one tap, its loose

I've resorted to using a hand impact driver. I have a set of JIS ends for my driver.
It has never worked out for me. I have always wound up destroying the heads and replacing the screws.

So, for context, I have three carb types in my possession:

1) Single Keihin / Mikuni / Oko / etc carbs. Basic slide operated units, no pumpers, no CV shenanigans, cheap and plentiful. On these if I bugger them up, who cares. Pull another from the eBay bin and move on with life. That said, I've never had one bugger up that badly. We're talking bowl and cap screws. They don't need any torque when installed. If you don't invite Andre the Giant over to 'set' your screws for you in the first place... JIS screwdrivers improve the situation, and on carbs that see the elements more I use never-seize. Even my chinese carbs haven't given me trouble. If I were to entertain using an hand impact driver on a carb, these would be the only ones.

2) Single expensive carbs, like a billet SmartCarb. For how much it costs, if anything looks at me funny it goes back to the mfg for R&R. Some of the parts involved are not available to me as a consumer to replace should I mess it up.

3) Rack of 4 Keihin FCRs. Look up the cost of a new rack, look at how thin many of the castings are. No fecking way am I using anything with the word 'impact' on these. I'm nursing a 15 year old rack as it is that's had to be helicoiled due to prior monkeys abusing it. The official Keihin importer in the US has a hard time getting some repair parts for these carbs, I'm not taking risks with them.

Ultrasonic bath time does wonderful things to 'stuck' hardware at times FYI...

Using the correct tool is also an acceptable method of removal.

Blasphemy!
