Carbs stuck, I can't get them off!

(1/2) > >>

I just bought a '73 that I'm in the process of pulling apart so that the frame can be powdercoated and the engine rebuilt. So far everything has been very easy but I've encountered a bit of a problem. I can't get the carbs off! Throttle cables are disconnected and the hose clamps have all been loosened as much as possible, yet I can't pull the carbs off. They are seriously stuck on those hoses.
Any tips to getting around this without damaging anything?  

Thanks!

ps. I'm new to the forum, so hello to all :)

On one of my 500s I used the handle of a hammer (the woodedn bit!) to lever them off.

Those carb rubbers can get awfully hard after many years.

A bit of WD40 probably wouldn't go amiss either.

Hi Andrew,
              Steve is correct, when the carb rubbers are new all it takes is to push down and back on the carbs and they will fall off. But with old stiff rubbers it gets to be more difficult. Presumably you have completely removed the airbox and slackened (or removed) the hose clips on the rubbers nearest the cylinder head ? This is for a CB750, not sure about others.
I have just replaced the carb rubbers on my 76 CB750F1 and the difference is amazing.

Cheers

Thanks for the quick responses!

Yes. I have removed the airbox :) and slackened the hose clips closest to the cylinder head (those stiff hoses have simply fused themselves on both ends).
I'll give it another try tomorrow with some WD40 and a hammer :evil:

What I didn't say is that I once broke a hammer handle by wedging it between the carbs and the cylinder head to lever the buggers off!!
