Re: baffling turbo..

I'll add that if you have modified it and its lean, it will work for a while
seemingly, then do the stuttering thing because the plugs are all eaten away
fast. gaps too large and the spark can't jump it under the harder loads. I
had shitfires to this to me but it was my fault for leaning it.
