Need a bit of advice please. The manifolds I have with my twin 40s don't have a take off for a servo. Should I get both manifolds tapped and use the balance pipe I've got from the Solexes that I took off? Is one take off each side correct or do I need to tap all 4 inlets and connect them up? Has anyone done this?
Just tap one, nearest to the hole in the chassis, for say a 13mm hose. Worth taking some time to see what the best position is for easy connection to the hose (I put mine in the wrong place ). Should be ok drilling/tapping for say a 1/4" NPT barb, but go easy with a tap that cuts a tapered thread: easy to widen the hole out too far. There should be enough meat on the manifold for the barb to screw into, with some teflon tape around the thread.
Embarrassing! Just went to get the manifolds to take them to be done and found they already have bosses with 13mm pipes for the servo. must have had my eyes shut when I took them out of the box
Apart from the pipe that runs down the bus from the servo to the manifold, can anyone tell me what the other pipe (same diameter) is for that runs under the drivers seat and seems to disappear into the bodywork under the drivers door? Or is this another mega bodge I've found?
Phew! It had me worried after finding a spark plug where the one-way valve should be! So is this servo exhaust blanked off or does it open into the bodywork?
