What do you EU pilot use to clean the fuel injectors? I can’t find a place to buy the Hoppes #9 gun cleaner that Lycoming refers to. I know you can use MEK or Acetone but was wondering if there is a “favorite” cleaner.
Also, anti seize for the spark plugs that doesn’t contain graphite?
Graphite-free anti-seize for spark plugs is a copper grease, refer to SI 1042AH.
For injectors, I’d just go with acetone or MEK, but in an ultrasonic apparatus.
Use the Champion stuff. No copper else you get a wild jump in the oil analysis 
For soaking injectors, MEK is great.

That’s where I found it but I am told that the Champion paste has graphite in it. Do you have a specific brand or part number you use?

Thanks!

To be honest, we use some generic stuff that’s too cheap to contain anything beyond copper and oil… maybe also some thickener 
What about this one?

Found that Lycoming approves this one: LOCTITE® LB 8008 C5-A
The LB8008 stuff sounds good. Good temperature spec.
However “with copper and graphite suspended in high quality grease” tells us that it will screw up oil analysis pretty well. Admittedly most people don’t do oil analysis
