is there a gasket for intake manifolds or carburettors that you can easily change either the manifold or carburettor over without haveing to install a new gastget and use the gasket goo stuff?

i'd like to be able to quickly change between carbs.
small for working days and big for weekends.

No
No easy way and dont use gasket goo - either the aviation type or the silastic type. Just dont do it.

The manifold gasket is a one long gasket that covers both the inlet and exhaust. Its not that hard with a long skinny socket and the manifold just slips back off the studs.

Mike

we it be okay for continually changing the manifold? or should you change the gasket every time you change the manifold as well?

i've reused gaskets at times without problems..

why do you want to change carburettors though?
leave the big one on, if its tuned properly it shouldnt use more fuel than the other one driven carefully?

I quite often change the inlet manifold + carby as a single unit, leaving the exhaust manifold and gasket in place. Never had a problem. It depends on what gasket you use, it is better to use a metal backed one as the standard type can blow. If you do this always spray a bit of carb cleaner around the manifold to check for air leaks afterwards.

How big is your big(weekend) one?

are you using 2 of the same type of carby ie SU's or an SU for weekdays and something sexier for the weekend?

(omg what have I started??? please note I was NOT suggesting SU's aren't sexy in the own right)

if you're alternating between 2 SU's is there any chance you could modify a manifold to fit both?

If it were possible to do it that way you'd have much less gasket to play around with - less chance of inlet or exhaust leaks I'd have thought

Just an idea

You could always stick velcro between the carby and manifold. Just peel off one carby and push on another one. It should leak as much air as re-using the gasket every week.

Victa Lawnmowers have a carby that is fitted bayonnet style. Just push and twist the carby to remove it.

Swapping inlet manifolds and leaving exhaust is no problem, the gasket will be fine. WIth heat from the exhaust (and time) the gasket sticks its self to the head, but should not stick its self to the inlet mani (too much) unless you're getting some serious heat sick through the inlet.
Swapping carbs between week and track day isn't uncommon I wouldn't have thought - eg SU for drivability and then 45 for more top end.

If removal of the inlet manifold damages the gasket slightly, I put a smear of Loctite 515 `Master Gasket' on the gasket before bolting the manifold back on.
Can't see `why' you would need to keep changing the manifold...
Pick a carby and make it work.
