My cable was fairly short since I had the linear gear rack to rotary contraption mounted on the back side of the firewall. My cable was somewhere around a foot or so long IIRC and had no issues with flex or leaking.
I removed the choke from mine and welded blocks on two intake manifolds right where they went into the heads and threaded for primer nozzles and it worked great. I didn't like the idea of a choke that could accidently get closed, but if you are careful a choke if O.K. -------- Original Message -------- Subject: KR> Re: Carbs for VW based engines From: "smwood" <[email protected]> List-Post: [email protected] Date: Fri, November 23, 2012 6:39 pm To: <[email protected]> I have a Zenith carb on my GPASC 2180 VW. I rigged a mixture control using a VW speedometer cable. The mixture needle has too much friction from the sealing gasket. The speedometer cable will wind up a full turn or more before enough torque is applied to turn the needle. I will need both hands to do a mixture change. If I loosen the gland nut enough to smooth out the turning action, then fuel will leak around the needle shaft and drip on the cowl and exhaust pipe. Until I can find a better control arrangement, I have set the mixture to what seems about right, tightened the needle gland nut and don't attempt further mixture changes while the engine is running. Far from satisfactory since I have three systems for showing mixture operation: 4 cylinder head temperature sensors, 4 EGT sensors and a digital 14point7 Mixture Meter, and still cannot change the mixture setting in flight. Choke operation for starting and smoothing out running for warm up works great. Incidentally, the Great Plains carb model numbers are not the Zenith carb model numbers. The Great Plains carb model numbers correspond to the approximate displacement of the VW engines.
