It's also good to practice portng when starting out on cheap thngs like a whipper snipper,helps with getting used to the tools you are using and how they cut and best way to hold them ,one slip and you can hit the bore and thats not a good thing.Good lghting is a must also...The porting it self does not take that long its the researching and working out what and why to come up with best plan of attack for the engine your working on..With this engine Im aiming for more torque fingers crossed lol ..I will no as soon as I use it if it has worked and is pulling the chain with more authority...Cheers
