compression , fuel draw, spark , no pop ? I Think its the CH ignition battery , 4.8 500mah, because the more
you flip it the less and less spark you get . the ignition was checked out by adrian at CH , SO its fine.
i think i ought to try a 1200 mah battery , then i will get a fat blue spark for a longer time . everything else
looks fine , any help apreciated.
