i have a ntc3 pullstart and i just got a starter box to make life easy.in order to use the starter box what changes do i have to do or can i just take out the spring of the pullstarter.
You can do one of two things.
1) Do nothing.
or
2) Convert your engine from a pull-start to a non-pull-start. In order to do this, you need a new backplate and gasket, and either a new crankshaft, or cut the pull-start pin off the end of your existing crankshaft. Without the pull start, you also have the option of using a smaller diameter flywheel along with lowered motor mounts.
I wouldn't do anything with the spring.
thanks tom. not a thing sounds good to me
