Ed,
Since lead melts at a relatively low temp have your tried using a
propane torch to heat the plugs and let the lead drip off.
I don't know if it would work but it might be worth a try.
Actually, I did, Todd. They guy
sent me a complimentary spot of the stuff. I flew with it for over 20
hours and it not only did not help but actually seemed to leave more
deposits. In the end after some research on the topic, I came to the
conclusion that the temperatures did not go high enough to cause the
chemical reaction that bound the lead. In other words, it would work
with the high temperatures reached in air cooled cylinder heads but
apparently not with the lower temp water cooled blocks. At least, that
was my conclusion.
One of these days, I am going to find
a heavy duty ultrasonic cleaner and see if that might "buzz" the lead
deposit off the ceramic (without pulverizing the ceramic). Typical
abrasive blasting does not work very well due to the shrouding effect of the
multiple ground electrodes which tend to shield the ceramic
cone.
Thanks for bring it to my
attention
Ed

Hi
Ed;
I recall a few years ago you were trying a few witch's potions
in your quest to remove lead from your plugs. Did you ever try this
stuff?

Decalin
RunUp™ Fuel Additive in a 16 or 32 ounce bottle, use at
1/2 oz per 10 gallons fuel.
- Helps prevent
rough running due to plug fouling
- Upgraded
formulation to combat combustion chamber deposits.
- Prevents valve
seat erosion from valve seat micro welding.
- Does not
contain volatile solvents so it is safe to ship and safe in
the cockpit. You can carry it with you for out-of-town
airports.
- Easy to use
graduated measuring and dispensing reservoir built into the
bottle. No messy syringes!
- Tested and
stable down to 0 degrees F.

Decalin RunUp is not approved for use in the
engines of certified aircraft but it has the same active ingredient,
Tri Cresyl
Phosphate as our previous product. Lycoming
clone users have reported very good results when using this
product.
Notes on using Decalin RunUp
:
Some white deposits may be seen on the plugs
and in the exhaust pipe during use; this is normal with RunUp since
the lead in the fuel is being converted to non conductive lead
phosphate. When no additive is used, lead oxide is
formed. It is lead oxide which causes plugs to misfire due to
its partial conductivity shorting out the plug. In addition,
lead oxide tends to form in large clumps or clinkers whereas the
lead phosphate is crumbly and if any is left behind in the
combustion chamber it deposits in even layers.
Make sure you remove and clean your oxygen
sensor every 20 hours to remove these lead phosphate deposits when
using Decalin RunUp.
The dosage of 1/2 ounce per ten gallons of
fuel is a minimum. This can be increased to a maximum of 2
ounces per gallon for problem
engines. |
