Why won't your 76 vw start It's been sitting outside a while whilst you wait for a part to pass the MOT you have charged the battery but on re-fitting it the bus still doesn't start?

well for starters if you set the battery directly on the ground that will immediatly kill/drain the battery of all its juice. if you charged it and put it back in and still nothing your battery could be dead. if you turn the key and you hear kind of like a winding sound like something is spinning then hold the key down for a good 10 seconds, turn it all the way back to the off position and try it again if nothing happens then it could be your spark plugs. you can pull those and clean'em up a bit. re-gap them with a feeler gauge if need be spray a little dw-40 on them put them back in, make sure all the wires are put back on properly and try it again.

a good book to have is john muirs "how to keep your VW alive" in my opinion its the holy bible of VW books.

you can go to an old bookstore and probly pick one up for about $10

now let me tell you this, i dont own a bus, i have a bug so im just going off my knowledge from working on my bug. so just remember im not a certified technition.
