« on: February 12, 2016, 01:39:37 am »
How is every one? My name is David from land down under I came across this awesome forum so I tought I join in and learn a few things. I am not a chain saw guy but I am in a hobby that uses similar 2t motors. The motor I play around with are Zenoah or Chang Yeng short CY but there are other motor out there as well. I would love realy love to learn how to port my own engines for better performance but most importantly I just love to learn new things. I do have a rough idea of tools req for the job also roughly how to port do's and donts but I would love to hear more form you guys. I know there are a lot of info on this forum and if some one could please link some of those threads I would appreciate it. I have posted two photos of the engines I run in my rc car one is a reed and the other is a piston port. Please guys/gals hit me up with any info and advice you have.

All the principles are the same. The squish clearance is the same .020" or .5mm figure.

Reeds are not used much in current chainsaws and other OPE's like weed whackers etc.

The chainsaw guys often play around with the 48cc to 64cc saws. Not so much with the 30cc size. But like I said, all the ideas are the same.

The current name brand professional chainsaws will run right up against 14,000 rpm right off the shelf show room stock.

Hay thanx Magnum for ur reply! Yes I agree they are very similar but from what I understand the saw motors don't have as much torque n they don't rev as high! Thanx for the links dude. Man this forum is full of awsome knowledge not like the rc forums where every one compeates with how much money they can spend! So if I want to post questions which part of the forum is best?

My saws saws run at least 12,000 rpm and some run 14,000 right from the factory unmodified.

Take your pick as to where to post? Depends on what you are trying to do.

If you are going to do lathe or milling machine work?
Cutting and grinding? Porting mods. Timing figures?
Gaskets?

Use the "How to" section?
RC section?
