Wrong fuel/oil mix - Force 50 backfire

[sinker0422]

Ok, I just bought an '86 force 50 that's been sitting for a couple years. It had a bad condenser. I replaced it, and it ran perfect for about 20 minutes or so. I pulled the plugs, and they were coated with oil. Turns out, I had mixed the gas at 16:1 instead of 50:1 (should have checked this website first). I'm getting ready to replace the gas, but I need to know if an incorrect mixture will cause it to backfire. When I try to start it, my neighbors hit the ground. Will replacing the gas stop the backfire, or is the timing off? Any ideas?

Seems to me that 16/1 would make the fuel/air mixture quite lean, which could well lead to backfires. Comments, anyone?

at least you didn't put diesel in your tank by accident like i did ...... hahahaha engine didn't run well at all, the tank was half with normal fuel and I added about a quarter extra of the diesel (it was dark) anyway .... cleared it out and added fresh fuel and it was good to go .....
