im using a genuine wt603 walbro

my old girl fires first or 3rd pull cold & i still have the poxy china brand plug ??
one thing tho i dont use a timing key on my 15:1 kit some bikes like em some dont depending on timing on crank & flywheel there are so many different factorys churning out bits .5 to 1 mm can make a hell of a difference with timing

if u throw a genuine walbro on that RD engine ill bet it will rev much harder n alot quicker off the mark
throw on a jet pro rep ya will be leaning over the front to keep her down when ya hitting it out of corners
