"This is the 12-piece kit. The distributor is at the mid-mounted engine, so plan bed access and inspect for oil inside the cap - a classic Acty misfire cause."
Frequently Asked Questions
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.
Will a tune-up fix a rough idle?
If the idle is tired ignition and dirty filters, yes - a full tune-up is the reset; a vacuum leak or carb fault needs separate attention.
Should I change the oil with this?
Yes - do the oil and filter with the tune-up so all the fresh service starts together.
