Unfinished projects king.
today i wired a killswitch into my lawnmower (which is, of course a victa) so i thought i might post up what i did(i know its on a lawnmower but it doesnt make a difference, its still killing the engine). you need to do this if you put a different carby on because the kill switch is built in to the carby. The basic concept is if you ground the wire then the engines spark gets cut, fairly simple and how just about every small engines kill swith works (so yes, this will work for other engines).
what you need:
1 switch
2x how ever much wire is apropriate(i used the wiring from one of those $2 corded R/C cars)
some heat shrink or electrical tape or similar
*please note* i have the really really old version(40+ years old) of the removable cylinder type that has a slightly different ignition system and has the pull start on the top, with the air cowling removed it looks like this
were as the later model ones that have the pull start on the side and the coil on the outside of the flywheel that look like this with the aircowling off(and other bits aswell but you get the idea)
Power Torque engines have the same carby so the same thing works.
Heres what i did:
first i removed the wires, we only want to use the the wire conected to the piece of copper the screwdriver is touching in the pic below(which i will from now on refer to as wire 1)
IF you have the same motor as me and not one of the other 2 types you can just throw away the other piece of wire that plugs into the rubber thingy next to the copper piece(which i will from now on refer to as wire 2), authough i kept the ring thats on one end of it and used it to secure the earth, as can be seen in the last picture. with the other engines both the wires are connected directly to the coil and condenser.
connect one end of your new wire to wire 1 and the other end to one of the terminals on your switch, once you have done that you have to options, they are:
1) have a small piece of wire going from the free terminal on your switch to the nearest part of your go kart and bolted there as an earth and if you have one of the 2 engines different to mine you will probably have to earth wire 2 as well. this will work 99% of the time.
2) if you dont know what i mean in the 1st option then do this one. simply run another piece of wire from the free terminal on the switch back to the engine and connect it to the engine(look at the way ive done it in the last pic), or if you have one of the other 2 engines the connect it back to wire 2.
heres a pic of the wiring on my engine, the wire that is bolted on with the loop. the other wire is wire 1
remember if you use a normal switch labeled on/off the when the the switch is "on" then your engine wont run because its earthing the wires and thus killing the spark, make sure the switch is on the off position when your running you engine.
also dont forget to cover any exposed wires with heatshrink or similar, you dont want the bare wire touching some metal and killing your engine do you?
and now you have a kill switch that can be mounted anywhere on your kart you like!
its basically the same for every engine siutable for a kart so it really aplies to anything.
i hope this helps some people
