Stripping carbs

[hjp1968]

I had my carbs off the other day to set the valve clearances, all the exhausts were within spec but all the inlet had tightened up. I thought I would have a look to see how the emulsuion tubes were as it seems to be running rich at the bottom end as the choke can be knocked off after about 5 seconds of start up!
Anyway I tried to undo the screws on the float bowels and the little buggers would not shift and I felt that I would just end chewing them up,them didn't have a single mark on them so I think they have been undone from new. Does anyone have a handy hint or knack to get the little blighters off?

A bit of heat (carefully of course!) should get them pretty easily, just make sure you've got a big enough screw driver so you don't strip the heads.

Failing that, a cut across the top of the screw head with a Dremel & use a big flathead.

HTH.

Heat, on carbs?
Nahhhhh, an IMPACT DRIVER is your friend and need in this situation:

I never tackle Philips headed screws without one, as soon as you take the edges out of the screw heads without them moving you`ve got a LOT more work ahead of you.
Use an impact driver, job done!

I used vice grips to take mine off and then replaced them all with allen headed bolts. The originals were butter and the impact driver just smeared them.

I did say CAREFULLY! That's what I did, worked a treat. I couldn't foresee a way to hold the carbs & not smack them with a hammer using the impact driver method

Impact driver was not touching them, it looked like it was more likely to take the centre out!!!! I may try a combo of good screw driver and mole grips!

Had the same problem I think I used a very small cold chisel on the circumference of the screw and mole grips. Carbs were off the bike and gripped very gently / carefully in a vice. replace with stainless allen keys

definately not heat on carbs..too many delicate internals and that funny stuff called FUEL
Wurth make a product called rostoff; its a cold spray used to loosen fasteners.
perhaps in conjunction with some form of persuasion ... mole(vice) grips and /or impact driver.
maybe dummy mount the carbs to something solid to help you out.
good luck
cheers

Anyone remember the size of the screws so I can get them in before I start my butchery
To limit my time off road, Oh by the way anyone know the cheapest place to get the pull throttle cable?
Thanks

Venhills will sell you new inner cables which as the outer cables are seldom damaged is a cheap option. They also have all the stuff to make up any cable you want
