Screw size for kill switch?

[The Silver Duck]

Does anyone know the screw size I need for the two factory holes on the tins of a flathead where the kill switch bracket goes?

Thanks!

#10 sheet metal screws with 5/16" head (I believe.) Personally, we used to remove all the kill switches from them when they came that way from the factory.

I agree only kill switch you need on a flathead is a zip tie on the plug wire

Well, sorta.
Pulling the plug wire and leaving nowhere for the voltage to discharge to (ground) is very hard on the coil. I put a wire tie on it simply for emergency situations (track/corner worker needs to shut the engine off quickly in the event of a crash.) Like many, I've pulled the plug wire on the coil for years myself -- habit without reprecussion doesn't make it right though.

I put kill switches on our own engines so that the boys can shut the engine off on their own if needed. I use a 30A steel toggle switch though, not the el-cheapo oem switch.

My kill switch is mounted at the top of the steering wheel were it can easily be reached. Longacre makes a nice switch. #45470 http://www.longacreracing.com/products.aspx?prodid=7541
