I personally always mixed rich even back in the 80's. I still run 32:1 even with today's better oil. I was surprised you guys mentioned straight gas because the very small amount in the tank when I got it looked clear...very possible no oil mix. I plan on new top end and go from there. I gave the guy $250 not running and guy thought it needed new top end. I actually hope it was just straight gas that caused this and not another problem so should be good after new top end. Thanks for all the help and opinions.
