I'm running 10% nitro, 18% full synthetic oil...

What am I doing wrong?

I haven't run it lean, in fact I'm running it rather rich, as the engine is still very new. If I run it richer, it will start to four stroke and I don't want that...

I've read post of people running up to 15% nitro in their West engines... So I thought I was on the safe side.

And I haven't even shortened the header yet. Well, I have shortened it today, and I tried to start it to see how it would do, but the plug was gone... and I'm out of cold plugs...

I might try a tank of 0% nitro tomorrow, just to see how the engine does on that.

Did any of you speed freaks run your West engine on 0%?
If so, how does the engine react to that?

Of course, I wouldn't mind running 0% nitro...lost cheaper, but I just thought the engine needed some nitro to really come alive.

I'm using a Rossi R5 plug, so that should be ok IMO...
I could buy some R6 and R7 plugs, but I think that would be taking it too far... I thought I was already running a very cold plug with the R5...
Or maybe I should step up to Enya quality, but that would be very costly at the current plug eating rate...

Rudeboy,

Check your head bolts and make sure your carb is tight. You may have an air leak. What RPM are you turning, which prop?

I use enya 3 plugs in my engine & I haven't changed one for at least 30 flights. I am using an APC 8X8 prop & similar fuel to you.

Carb is tight... it came loose when I fired up the engine the first time, so I tightened it a little more after that.

I checked the head bolts before I installed the engine. They were not torqued equally, so I straightened that out too...

I'm running an APC 8x8 now.

I haven't checked RPM yet, as the engine is still new, and I know myself... when I dig out the tach, I will start to fiddle with things to get more...

An Enya 3?? That's a hot plug...

But hey, if it works for you, I might give it a try too...
