RE: GO .25 Breakin in (heat cycle) F-UP!
but what about break in? I'm starting to think that these plugs are fine, and its something else that's causing the stalling. There are no warning signs when it stalls, it simply revs as normal and stops. Even with the glow starter left on it is stalling. My 2-3 minute runs are lasting just 5-10 seconds before I'm having to restart. I've gone through half a tank and have started to lean it a little, to about 1-1.5 turns out from flush on the HSN and flush on the LSN. This is not helping the stalling however, it is just increasing temps a bit.
Any ideas? I hope its not an air leak, I have no silicone sealant, and cannot be arsed to take the engine apart mid break in!
