[T3] engine(carb) problems

["Herman Haustein" <haustein@netvision.net.il>]

Hi ,
My engine has been running extremely rich since I assembled it (350mi ago) -
about 8km/liter (about 18.5MPG).
It has also been running too cold lately (I can hold my hand infront of the
exhaust after an hours run).
And has a tendency to knock (ping ) even at quite high rev's.

1. What am I missing ? Carb's are overhauled - chokes open fully, timing
dead-on , valves adjusted ,etc.

2. How does the air-filter work (from where does the air enter ) ? - it
seems to be blocked by a weighted flap.

Herman
