Port n Polish

[biddie_gibbs]

how do you do a port n polish. how does it help your engine? also if i drill holes in muffler will it help? and how do you "play with the carb"? please help

Port and polish all it does is allow more gas/exhaust to go in and out quicker. It depends on your muffler, also it will get louder as you drill it out. Playing with the carb is just adjusting the screws to get the most performance.
