I always put Sta-Bil in my gas cans for lawn mower, snow blower, trimmer, etc. I recently bought some Sea Foam since my snow blower will only run when the choke is ON. I want to try to get it working correctly. Any suggestions are appreciated. My real question is: If I put Sea Foam in my gas when I buy it, do I need to use Sta-Bil? And, can I store my mower, trimmer, and snow blower with gas in the tank if I mix Sea Foam with the gas?
