so I did a little torture test today to see exactly what these engines would run on, my engine is a zoombicycles.com 80cc HT. so I usually run 20:1. I mixed up some 15:1 to see how the bike would run, and as it turns out the bike actually ran smoother and had more high end power than on 20:1! it was a tiny bit sluggish in the low rpms though, and there was a barely visible smoke cloud, so then I went to 10:1 again it seemed ok except for the largely evident smoke cloud and it was becoming noticeably sluggish in the low rpms, so I thought to myself "wow I'm just guna go all or nothing on this next mix" so I made up some 3:1!!!!! it was a thick dark blue sludge I didn't think would even be able to flow through the petcock, well after pedaling a block I finally came to a large hill, I coasted down the hill and popped the clutch, to my surprise the engine sprang to life!, it rode at 35+kph just as normal as it rode with the 20:1. Except a huge blue cloud that spewed out the back and a spray of oil. the second I let off the gas the engine started popping and misfiring really bad, it had no power under 20kph but along as I kept it revved up I could pedal to 20 then let of the clutch and ride, I rode for about 10 minutes and brought it home, I tried to keep it running but the second I get of the throttle it bogged down and took about 20 seconds to reach high rpms again, so I'm hugely surprised it actually ran(albeit poorly) on 3:1!!!! I wouldn't recommend this though as it's highly impractical and now I need to go clean the carb and exhaust and the tank thoroughly before I can ride again,
