That's what I was telling you, in a nutshell. You can have all the starter in the world AND you can toss in another 6 volt battery -your reference to 18 volts - but if the combination of batteries can't supply the necessary current (power) you won't spin the engine. Get it now?

No, i stil don't get it, the 18V battery i was using is capable of over 40amp draw while holding it's voltage and it would still not turn over this engine and that was the reason for preheating the engine with a heat gun, after the second tank the engine was loose enough to use my regular starter setup with no problems, remember this is a made in china engine and tolerances are not always spot on, so a tower engine from 2 years ago might have been loose enough to break in normally but from what i've been hearing the new batch has been extremly tight.
