ok so when some one asks you to Mod a $700 8th scale engine new out of the box, you will have the confidence to do so ? im not trying to take the piss, but you seem to know where to do this where to do that, and then you say you dont use a degree wheel. a std engine you will notice anything you do, but the best modders can take a high end motor and make it better. that is precision, and tools are needed to do so. so you really are just tinkering around. it takes time, money, and trial and error to make improvements to high end engines, and unless you use a degree wheel, you have no idea what you are doing to the crank. every post i read, you have an opinion about everyone elses problems, yet, you can not take note of the people that offer advice, you take it as a fight or a game. enough said, i will just steer clear of what you say, cause you have a way of saying things like you know how to sort this or that, but yet not really offer any help if you read it a few times. so good luck with your guess work. im sure in your mind you know what your doing, i Guess.
