I posted recently regarding tuning issues with my new CMB1.0 / SprintCat. No matter what the needle setting is, the boat just launches and dies. See ->
PAST THREAD
After spendng time at the local boat club it seems the issue is fuel delivery ie placement of the fuel tank and remote needle.
The tank is sitting below the carb centreline (up front) and the advice I've been given is to fit a Hopper tank or header tank. It also seems I have an excessive distance between the remote needle and the carb and this needs to be kept to a minimum.
Hoping someone who knows more about it than me can tell me a bit about the theory of hopper/header tanks, their construction and proper placement, operation and recommended size.
Also is it true that the distance between the remote needle and carb needs to be minimal? It is currently only 2 inches but maybe this is excessive.
Finally anyone else had the same issue with the remote needle CMB carb and are there any other viable solutions?
