engine eats plugs, on an on
my os vz-b (non turbo) eats plugs after 1 tank almost every plug tested died.
I´m running this in a xb8, using graupner 25% and orcan 25%fuel,whereas the graupner fuel is specially designed for os engines, orcan was only tested.
plugs were os 8,a3,a5 some other brands and heat ranges. all died quickly.
there is no visible damage to the coil, not even an anormal colouration.
the connecting rod bushing seems fine, no feelable play so far.
please help me, I don´t know what to do anymore.

Is the button pitted? How about the top of the piston? How long have you been running the engine?

Lean.
Are you running the tank dry every time? If so, when it gets low on fuel it'll start to lean out right on the last few drops of fuel.
Are there shims under the head button? Checking your temps with a temp gun?
You should see a stream of smoke coming the from exhaust at all times.

bottom end lean i'd guess. It probably isn't even running hot. But if the bottoms over lean you'll do plugs every run... I know .. I've done it

what kind of glow charger are you using? If you use the power panel kind make sure its pluigged into the yellow terminal side not the red and black terminal side or youll be sending 12v though that 1.5 volt plug...!!!

i´m using a 1,2 v sub-c batterie for the glow charger.
the connecting rod bearing seems fine, how to check the rear bearings?
thanks

hi
is such a rod slop feelable? mine seems good, but since I´m a nitro rookie maybe I overlooked something.
do you have a link for a how-to on nitro motor rebuild?
