Frequently Asked Questions

How do I know a tune-up is due?

Rough idle, weak throttle, a damp-weather misfire, or poor economy all point to a tune-up. Pull the plugs and open the cap - fouled plugs and a cracked or tracked cap confirm it.

In what order should I do a tune-up kit?

Work the ignition parts one at a time to keep the firing order, then do the filters, and change the oil with the filters so everything fresh starts together.

What should I do first with this kit?

Read the old plugs and open the cap for a quick health check, then work the ignition parts one at a time to keep the firing order.
