Thanks Guys all your advice, for taking out my engine, all i did was remove the 4 rear end screws in my right tvps and unhook my pipe and fuel tank then remove the 4 allens screw at the base of the engine mount not at the bottom and voila!!!! never thought that taking out my engine was that simple. i dont even have to adjust my gear mesh!!! bcoz my engine mount stays exaclty the same spot. wish i have pics to show you.... just like Benzzyo5 said.

Guys i just replaced the one way bearing (im suspecting the old one is ok) with a new one to be sure and then reassembled the engine and tried to finish my break in but i still got the same problem!!!! so i took the engine apart again all the way and remove the entire back plate --- the result is a broken backpressure spring as what my LHS calls it (wish i have pics) part 11143 i gues with a pin on it that connect from the crankshaft no wonder its not turning with the one way bearing. My LHS calls it a rare occurence especially that my engine is stil new, must have been a defected part. im gonna call HPI for a replacement and hopefully they respond soon.

As for the fuel, definitely will go with Byrons from now on , i think its a cleaner and better fuel lyk u guys said it. Like most NEWBIES theres always a first time for everything it just that we have to learn from our mistakes (and the HPI/factory mistakes!!!!!) and avoid doing it again!!! Thanks guys for all yor help i learned a lot!!!!

Always double check your mesh when removing the engine just to make sure its good still. Just hold one gear and wiggle the other if it has a little play its good.
