what oil mix are you running? where is the needle on the carb set to?i did they gave me a store that's 25 miles away, way too far for me to make a trip on my gas bike i think i may be sold on the expansion chamber as i have long steep hills i have to walk it up but as it sets i cant get up small steep hills without pedal assist it 5 mph in the videos on here mine doesn't rev up near what there's do mine sounds like a 4 stroke compared to theirs i have an old adjustable carb i traded for my new un adjustable cns carb for hopefully that helps
nope they're there. http://fc02.deviantart.net/fs70/f/2011/023/4/2/2_stroke_animation_by_thunderstorm996-d37x38d.gifSkarrd I like your avatar, I guess that engine has invisible transfer ports??? And from what Adam is saying, it sounds like he's running rich, low power on hills, oil dripping out muffler, etc. I reccomend getting a new NGK spark plug too, that might help things out a little. Good luck!
