u said 'u will fine out a point where engine starts to crumple because of reduced gas flow'
wot to do of that point?? i mean u r saying to adjust it when engine starts to crumble which means that there is not much gas coming to engine....
on the other hand u also said adjust it for optimum gas flow????
i didt understand, should i tight the screw when engine is crumbling or should i tight the screw when engine is at its highest rpm (bcz of more gas into engine) can u plz explain a litle
