How do small petrol engines stop?

[mikecotterill]

Hi guys I'm trying to get a kohler v twin engine working, I've got it running after a fashion but it won't stop on the key. Do these stop off the ignition like a car or is it a petrol cut off ? Cheers guys

i would have thought that it stops sparking so perhaps the earth is not earthing?

[Breezeblock]

most small engines are earthed to stop them theres a shorting wire comes from the coil

All the above .

Mmm ok well it's going on an rg25 grinder, there's only four wires on the ignition switch one to the power on the starter one for the power to the starter solenoid one to a wire in the carb and one that I'm unsure where it goes, will have to get out the multi meter and have a good poke, cheers guys

What ever you do, do NOT connect the earth cut out wire from the ignition coil to a live source or you will fry the coil, i would find the wire and feed it to a seperate switch.

What voltages should I be looking for on this wire? I have one that only shows 12v when running but not when ignition on?

I found a wiring diagram for a Kohler a while back if I remember there is a feed to the starter a live from the battery an earth and a wire from the coil in the off position the earth is linked to ground in the run position there is nothing connected and in the start position the starter is linked to the battery

There should be zero voltage fronm the wire, it mearly earths the coil out, if in any dout remove the blower housing to expose the coil, the wire will connect to a terminal on the back of the coil.

If you give me your email address I can email you a kohler v twin handbook that has wiring diagrams
