hello there
my beta 270 has a annoying running problem. when i want to go up a climb if i blip the throttle at the bottom of the incline it sort of restricts or doesn't rev up cleanly if i shut off and then feed it through gently it runs fine, but by then i have lost the momentum. this is the only time i get this problem. i have new plug, filter, oil, run on 60/1 fuel mix.
any suggestions would be very grateful,
many thanks
mark
