Skwerl58 633 #1 Posted May 16, 2022 I have been trying to get the 1970 GT 14 running. Rebuilt the carb, cleaned the tank, replaced the fuel lines with a new filter and no fuel is getting to the carb. It has the factory fuel pump still intact and want to know what is the best route to take, a rebuild or replacement. Also the ignition switch is shot and I need to replace it, it has four connections on the back, what switch number do I need? Thanks!! Share this post Link to post Share on other sites
Lee1977 6,216 #2 Posted May 16, 2022 Can't help you with the key switch. Best bet is to go electric on the fuel pump all new fuel pump for Kohlers are plastic and not very reliable. Same goes with the replacement kits for the metal pumps is what I hear. Don't have a Gt 14 so can't tell you how to wire it. I did put a electric fuel pump on my 520 ran hot wire to the switch with a 5 amp fuse so it would only run with the switch on. Ran the ground wire to a toggle switch on the dash then the other end to ground so I could run the carb dry if I wanted to. 3 Share this post Link to post Share on other sites
cafoose 3,135 #3 Posted May 17, 2022 The original ignition is breakerless and if that works I believe you need a different switch than you would need if it was converted to a battery/points ignition or you could burn up the breakerless ignition components which are both expensive and rare. First step is determine if you have breakerless or not. Breakerless has no points and points cover and a coil that looks like this: 2 Share this post Link to post Share on other sites
953 nut 51,648 #4 Posted May 17, 2022 I will go along with both @Lee1977 and @cafoose. I replaced the mechanical fuel pump with an electric pump and am very pleased with it. Mount the pump low because they are better pushers than suckers. I don't think a direct replacement ignition switch can be found for the GT-14. I replaced mine with a 103-991 switch and a five terminal block and Packard 56 terminals, NAPA has them. You can use the drawing below as a wiring guide. Your electric clutch will come from the "A" terminal along with the lights. 2 Share this post Link to post Share on other sites
