Got another problem just started tho when to start the beast up last nite and it wouldnt fire up until i put my foot half way down on the throttle and it fired up. With no smoke and idles fine starter moter goes fine wierd.

think the batterys ok
not sure about the spark plugs should be fine cos there new

any other ideas?

could be the throttle not set up right or its moved over the last 4 week

any help would be great.
