Before and after. Just using that wd40 degreaser that is safe for plastics and aluminum. Doesn’t turn aluminum black soaking cylinders etc either.
Spray on let set, spray off. But I add in a bristle brush then wipe down.

I ended up turning it down to a safe 12.8-13 tune. I think I seen in manual 14 was max. What it was at today when checking.
So yes H side Zama working great.

Good enough for dad. Because I know it won’t ever get this clean again.

Only things left to fix is the oil tank plug melted some by muffler and leaks now and new muffler I’m waiting on. Had to drill it to get it out. Never had to remove one before. Usually just missing.

Might put some heat tape down there on side and muffler area too.

Just a warning on this. Every time I have replaced that plug it has been missing.

This one was still in it but had melted and started leaking. I tried picking at it etc to get it out. That never worked.
I ended up drilling a small hole in it to try and get out.

Don’t push to hard though. It will go downward into it.

Homemade and hardware store bought grub shown. No need for their part in manual.

Grub installed with red loctite . Talking pocket change cost.

It’s that simple for guys always asking here.

Just to show guys that ask. Here is that hole inside that you do not want to cover sticking the grub in use red or orange loctite.

You only go so deep while installing and cutting it's own threads.

Yes they have a warning not for plastics where stress cracking could occur on thermoplastics.
Which these cases are not.

I always have on these. Per stihl service manual.

Read the first line 2nd paragraph, straight from shop manual. It works been doing it for this for many many years now.

Plastic stihls have them in certain models. They used a plastic injected plug from factory that falls out over time.
Should have used the grub from get go IMO.
Common issue.

Then your saw will leak bar oil out beside their mufflers.
