Beta Rev 3 250 2004 Won't Start

Hi all. Wondered if you could help at all.

I've had my beta rev 3 for a few months now and after pitting a new piston and rings in it is struggling to start from cold. It will fire first kick when hot.

I have a good spark,

Loads of compression,

Clean air filter,

Clean carb,

Stator and coil clean and dry

Carb settings adjusted and now back to standard

I have noticed when I kick it over the exhaust fills with petrol. It fills up that much that it leaks out of the gasket. I took the exhaust off and had to tip it out there was that much.

Do you think it could be the jetting. I have checked the jet which is easy to remove from the bottom of the carb and if my memory serves me correctly it says 150?

I always drain the carb and turn the fuel off when it is put away.

Any advice would be greatly appreciated.

You need to remove(replace)and inspect the needle and seat in the carb. It could just be a float sticking or the float height needing adjustment. Have you ever read the post on proper adjustment of the carb that`s pinned on the Beta forum?
