How often do you adjust valves on 850 suzuki c50?
First of all, it's not 850cc, it's 805cc. You want to adjust your valves when they get noticeably louder or quieter. Louder = loose. Quieter = tight. Loose is better than tight. Too tight can lead to burnt valves and low compression. I adjust my valves at the start of every season.
What is a burnt valve in a motor of a car?
a burnt valve looks like a wide crack in a valves' head. when a motor runs too lean, the cylinders heat up too much, causing the head of the valve to heat up faster than it can dissipate the heat, causing the valves' head to crack. once the valves' head starts cracking or melting away, you lose compression in that cylinder, and the engin will vibrate and it may not idle at all.

If the pistons are bad it should be smoking a bright blue color out of the exhaust. Are if a piston skirt is broken it should be knocking all the time. If there is a whole burnt in the piston you will not have any compression on that cylinder. Most of the time pistons just don't go bad.
What will cause a 1985 Chevy Celebrity to backfire checked timing compression both good vacuum gauge indicates valve timing out but heard flat cam and burnt valves or is it a timing set?
Since the compression is good I would not expect it to be a burnt valve. It could be timing if the timing chain has excess play. I would also check the ignition module and the engine control module. We had a 1986 Chevy Celebrity that had an ignition problem that cause it to run badly and backfire. The service engine soon light was blinking but not posting a code. We changed the engine control module and it fixed the problem.
You had three burnt valves in your cars engine The mechanic opened up the engine and changed those three only and closed it back up The car is now running fine but was that the right way to fix it?
Well that depends on whose money, and what his work order said to do, and the cause for the valves to have been burnt, if hey burnt due to a lean condition that caused them 3 to fail earley then sure it is ok, some purest would insist on have all the valves done at once, but if it is alow mile car or a tigh budget you could get another 100,000 miles out the head the way it was fixed. I would say, overall yes and the proof is in the pudding, IE it runs fine.
