Thanks Randy, I know what happens, I was just trying to encourage a bit of discussion. I have adjustable cam sprockets (RPM of course) on my engines for both of the reasons mentioned to return the timing to spec. My current engine has 250,000km on it and is untouched except for the adjustable sprockets, without them the timing is way off.  All it's vitals are otherwise perfect, I attribute this entirely to the oil I use.  :biggrin:

Noel,
Did you actually degree the cams or simply set cams with the timing marks in the windows and use the slotted sprockets to remove any slack?  How far off do you estimate the timing had degraded?

David, I used the timing marks in the windows. IMO that is accurate enough, especially for road use. The timing was out about half a tooth, that was 50k ago and I've not checked since.

Mike m - DO NOT FALL for this... it is a PANDORA'S BOX, and it can only end in misery.   :Facepalm:

Uh Oh... and just when things were starting to settle down...!!!

Fear not gentlemen, just in case the humour in that claim was lost in translation, I have neither favourite brand or grade and couldn't even tell you what's in there at the moment.

My pickup coils are modified so the ignition can be advanced.I ran along while without knowing that the ignition was advanced that much.Idk how to tell how much advanced it can be with the mod the previous owner dione

Pat Conlon

Most FJ ignition advance comes from modified rotors...not so much from the pick up coils or coil plate.
I'm not aware of modifying the pick up coils.

The mounting holes on the pickup plate are oblonged.loosening the 2 mounting screws and turning the plate clockwise I'm assuming advanced the timing.I'll send a pics of what was done to my pickup plate.

Well, we finally got all of Mike's parts here at the shop to sort out the best way to move forward.

He does have a 1219 Wiseco kit installed. Unfortunately two of the four piston were damaged. Then there was the damaged sleeve, I really have no explanation for how that happened.

So, we have decided the best course of action.

Head: Complete valve job, new RPM valve stem seals, new valve springs and head surface.
     The exhaust seats are pitted pretty bad and several bad valves stem seals allowed oil to flow onto the valve. You can see by the carbon build up on the intake & exhaust valves.

Cylinder: Replace all four sleeves as the are too large for the 1219 pistons. Size the new sleeves back to the pistons. File fit the piston rings and surface the gasket surface.

Carbs: Rebuild with proper jetting for larger bore. Plus, repair all of the issue located in the carbs.
     I found two slides with a bunch of holes at the mounting flange surface. There was a crack in one of the float bowls and the fuel line will be replace with the proper set-up. Also, all four choke plungers are just about to wear through.

I have attached a few photos.

Once Mike gets everything back, he will be able to assemble and ride without any further ongoing issues.

How come the space between cylinders 1-2 is smaller than between 3-4?
