Took my craft for its first test flight but I have a flooding problem with 1 of the mikuni carbs. The engine runs fine for about 5 to 10 minues or so then starts to flood. There is then fuel flowing out from the craby. Anyone have any ideas on what could cause this problem as it does not seem to flood immediately and is ok if running at full throttle.

Hi Mate had a similar problem a few years back, was caused by small bits of crud getting stuck between the needles and seats cleaned them out had same problem again, http://hovercraft.org.uk/images/icons/smiley_icons/icon_rolleyes.gif

I then went to a bike shop and had the needles changed for rubber tipped needles problem solved http://hovercraft.org.uk/images/icons/smiley_icons/icon_biggrin.gif .

could also be the float sticking or incorrectly set.

Turned out to be a build up of crud in the neadle seat. Cleaned it out and flooding problem solved.
