C'mon Harry, if it has cracked, you should be able to SEE it!
And if it is true, something HAS to be done, right?

Probable, but highly unlikely.

A carburettor works on the venturi principle. Slide is the device which controls the venturi dia. I suggest reading up on HowStuffWorks "How does a carburetor work?", lest I confuse you.

Basically, it is cylinder with a cutaway which regulates fuel going into you engine. If cracked, it can upset the working of the carburettor(making the mixture lean, would be my guess) and cause some side effects. I am not sure about the low FE, but if your mechanic is trustworthy, then maybe he is not trying to pull a fast one on you.

Slide should not cost too much, especially for an M800. Changing it should be less than half-hour job.

edit : - I realise that the link I provided does not show the working of a slide type carburettor. You could refer to the thread http://www.team-bhp.com/forum/motorb...-rd-350-a.html (Help Carburetor....Bullet 500>>or<<RD 350) to see the innards of a carb. Part 20 is the slide. Should be fairly similar in the Maruti.

If the Maruti carb is a butterfly valve type, maybe he means the butterfly is cracked? Can someone comment on this?

Harry, m800 carb doesn't have a slide. They have throttle butterfly. Is it that what is cracked? You can visually inspect it by taking off the air cleaner assembply and peeking down the venturi.
