How to use and read timing degree wheel?

[drf256]

Case comp is intake close to transfer open.

Thanks. I had that wrong

How do you achieve this?

Run the piston close to tdc and set the pointer to 0. Roll to intake. Check number. Roll on through and back. Check number. Move pointer to the center of those 2. Roll around and check again. If they're the same go to the exhaust and transfers.

And what is the benefit of this. When you say move pointer, do you mean divide the difference in two and loosen and turn the wheel or physically move the pointer. Also do you still end up with the same numbers as everyone else using the "standard method"?

Move the pointer. Mine is wire. Same numbers as everyone else.

Ben, I'll work on making a video on timing. I really thought Randy's was excellent on how to get TDC, but I'll try working on one that is more complete. I have off next week, so hopefully I can get to it.

I get that there is a lot of technical information to this. Maybe I need to start a second thread about port timing and why you want 100° or close to it exhaust and 70° intake and what does that even mean. Short or long blowdown? What do you look for for more torque/rpm? This is a discussion that could go on and on, and I hope it does. I hope you guys share all you are willing to.

Subbing thanks for this thread

What is very complicated is that what works for one saw will often not work for another. That is why the builders "book of knowledge" is so valuable.

It is also about angles & size, and more is not always better.

In short, a good builder is easily worth the money, and don't play with your favorite saw if it is your first time!

not the best vid

hope it helps

Thank you guys for contributing. I certainly understand that there is way more to getting the full potential our of a saw than just timing, it's another tooth on the gear. The thing is I read all the time builders wanting their intake and exhaust at 70° and 100° respectively. And you don't want your intake duration too long. Why is all this in the most general sense.

 

[mdavlee]

Too long of intake doesn't push the transfer charge as much.

 

[idiotwithasaw]

Is that the same as case pressure?

I'll have to go to the computer to flip it. If You can't understand Appalachian American then I'll have to hire an interpreter

Great thread men.

 

[jmssaws]

I agree, great thread.

It will seem confusing until you get it then it's very simple, I'm a degree guy from tdc but I'm switching to duration.

You guys learned me something today. I'm definitely gonna be referencing this thread a lot. Thanks guys, seriously good stuff here

Why are you switching?

Wonder how many of us speach Appalachian american here?
