i have a 6.5 Honda motor with the stock steel flywheel,i have put a 5.5 head on it which has made a good bit of difference and tying to get a little more out of it , i came across a 5.5 (160) push lawnmower with an aluminum flywheel, will this work and if so is there any thing i need to do, and do you think it will give me that much more?
