white powder in second user carb

Hi all

In my mad quest to rebuild my blown up '99 Fe400, I've now got a fe600 engine complete with carb.

Supposedly a good runner but who knows. Anyway, it wouldnt fit in my fe400 frame (99 e-start version) so I bought a frame too from someone else, and engine plates, and plastics, and a tank so basically ive got a new bike near as dammit!!

So, the frame is back together as a rolling chasis, the engine is sitting in it, I'm cleaning everything as I put it all back together, have changed the oil and filter etc - and thankfully no lumps of metal in either... which brings me to the actual question....

The carb- in taking the float chamber off and the fuel line filter, it was full or rather had a thick coating of white powder everywhere. What is it, how do i get rid of it and will it/is it likely to have done any damage?

Is this white powder just oxidisation as a result of the carb standing for a while running dry and perhaps getting water in it? Will it dissolve if I put petrol back in it etc. Any clues anyone, I'm getting fristrated now, its two steps forward and one back at the moment and I just want to see if the bloody thing will actually run now....

At the moment with my 1.5 husabergs, I've had 3 hours of fun and around 50 hours of heartache, dismantling and rebuilding, one blown engine and around £2000 quid all told. The cost per hour therefore is getting damned ridiculous and I cant afford to pay for any more new bits.... I've got a 38 dellorto from the old engine but was trying to use the 40 because of the bigger cc engine but am wondering if i should try the 38 carb. At least I know it worked.

Wish me luck.... and give me a clue anyone
 
That white powder stuff is a mixture of evaporated gas and aluminum oxidation. No worries, clean the carb and run it. Use some contact cleaner, and compressed air, get that stuff out of all the air passages. This is a common problem on motorcycles that have been stored for long periods of time and the carb was not drained.
