RE: fricken savage!
first EVERYONE PLAY NICE.
ok.. now that that is out of the way.
are you getting smoke at full speed? you want a good amout of smoke comeing from the exhast without it spitting fuel.
how is it cutting out.
is is sputtering and running rough then dies? or is it sagging then cutting off.
if its sputtering you are too rich and are flooding out. if its sagging it lean.
also change out the glow plug. it might be on its way out.
check these things then let us know how its running.
