Fossa always come up with some surprises! Found the fuel starvation solution! WILL TEACH ME TO CHECK EVERYTHING IN FUTURE.
In all my years of using carburetors I have never seen one this dirty. The wet powder was virtually a solid. Exactly what it was, still not sure. Can only suspect rust from the fuel tank. This raises a question of how clean our fuel is. The tank was clean during assembly. Will remove and confirm tank condition in the nearby future while monitoring the filters.
We stripped and reassembled the timing cover with some home made gaskets and a good quality silicone sealer. That has resolved our oil leak experienced at Kyalami.
14 October we will be testing Fossa at the Zwartkops Raceway during Trax Day. Would like to cut of a few seconds from our previous best, tick, tock …….
Still looking for a sponsor that can assist with race entries, fuel and some semi slicks. Dreams
