At first I thought this is the case, then I tried leaning it out 1/16 - 1/8 each turn, and as I mentioned before, the engine would not fire up at all if it's not on dead spot on factory which is 5 turn out LSN, with 5 turn out LSN the engine fire up easily but dies the millisecond I removed the glowplug heater...
I went through 3 new plugs thinking it might be the plug, waited an hour to charge up my plug heater too.... Then after I tried WOT up to 302F with plug heater attached (WOT with heater removed also kills the engine), cooled the engine down, heat the engine up, then that's it, problem gone, switched back to the very first plug, worked, so it definitely wasn't the plug..... Now I can start the engine with a single bump with any setting, rich or lean and now I can comfortably start the actual break in process keeping it at 200F with visible smoke trail, idle well normal or upsidedown and very very accepting to tweaks...
Well the actual problem is fixed now and I can see based on what I observed right now that this engine will be better than OS, but I cannot still understand why my engine behaved like it used to be before my crazy WOT attempt?
As for my statement about bad manufacturing tolerances, pardon me Novarossi fans (not directed to you Houston, you were the only one who gave useful response, for that I thank you), but how do you explain the 3001 shim that I purchased wouldn't fit on the head? I tried heating up the shim with cloth iron set on high tried heat gun too but still it wouldn't fit, wasted 3 shims trying it and finally dremelled the last one to fit. How is that not a bad manufacturing tolerance? It was only simple shims... If Novarossi could not make a properly fitting shim, how do I know they don't make wrong tolerance on my engine too? Did I bought a wrong shim size? I don't think so, the part number matches the manual exactly, I bought the whole thing from authorized dealer, sealed with Novarossi seal and the shim was smaller by point of a millimeter....
Don't get me wrong, I do not want to trash Novarossi and I don't think I am trashing it that bad when I blew up my steam on previous posts
The whole reason for me to buy a Novarossi was what I saw on the track, it sounds, look and perform so much more aggressive than OS definitely, and if I don't like it, I won't be spending my hard earned money on it. But what I experienced was definitely not good.....I heard many horror stories locally about nova engines, yet I still bought it despite the price and the stories, I was thinking if I can tune Webra (had worse hell on this brand but solved it eventually) and OS 4 stroke on heli and plane, I MUST be able to tune Novarossi too...Yes I am a happy camper now after my WOT attempt, but I know it shouldn't be like that...Peace....
