I have a question to ask about my 620 I put everything on the outside of my engine I don't know what to do it will miss one minute and then start running right the engine has a whining noise just wandering if you might have any ideas what my problem might be.
Whine? L series don't usually whine. Maybe the fan belt. There are spray on belt dressings you could try. I've rubbed a hard bar of soap on the belt sides while idling (very dangerous) to do the same thing.
What oil are you using? brand and viscosity? When changed last?
Pull the plugs and examine them. Dry black soot? wet and oily? Tan/light brown? Are any bright white porcelain?
Just wanted to say thank you for the help got my truck running again purrs like a kitten put wiring harness voltage regulator and distributor on the truck thanks to the Asian guy video I got it back in time thanks all God bless
