1. yup had a good look at manual, but ill have another skim through it
2. no i havent replaced the o ring, looks in good condition, but ill replace it just incase, but even when i dosent leak , it seems to die after starting ,
3.hmm steading flow, sort of like when your running a water tap at home and turn it down to when its still flowing but nearly about to start dripping
one other prob i have with it that maybe is causing it, is i think i might have threaded the thread in the tube that the jet screws into as it dosnt tighten when cap is on?
the reason i think its the carby float setup, is that before i pulled cap off it was running (not that well mind u) so silly me removed cap to see what was behind it, ive also changed spark plug, which i think helped as when it starts now it revs alot nicer now...before dying lol
anyway ill repace the o ring and see how i get on, otherwise think i just take it down to a lawn mower shop
