the backfiring might be a carberator problem,there could be water in your gas, and raw fuel may be burning in your exhaust. I would get new spark plugs and check your valve clearance and timing. Just my .02

Here's a pretty good tutorial on setting the valves. The guy has a website with a few other good videos too.
