Help With Port Timing

[Metals406]

true, if he quits now it's still useable. Might as well learn to use a degree wheel with it, the next one will go better I'm sure.

Exactly! Yes, he talks a little different than country folk... But he's just trying to learn. He has a pretty respectable wood shop, and tools. I think it's well within his capabilities to learn this saw stuff... He just needs time, and a little push in the right direction now and then.

I could always add a thicker gasket???

A thicker gasket will lower your compression..... a step in the wrong direction for performance.

Thicker gaskets may lend to other problems?.. Like the gasket blowing out.

I'm not sure how thick, the thickest gasket ever used was though? A 1/16th thicker than stock seems pretty thick to me?

I could be wrong though... Any gasket guru's feel free to chime in!

Yeah, what he said. LOL

Yeah, what he said. LOL

I actually just figured that out myself...:taped: :bang:

Don't worry, it runs fine. Cuts better.

Besides, a jug with me is like pennies...when I don't want to carry it anymore, I toss it in the basket in favor of another one...and another idea possibly?

PS... I never said anything about the squish other than saying NOW I understand what everyone was referring too when they mentioned squish...

Usually step 1 for me is to time some cuts for reference, measure squish, measure compression, and record all port timing numbers. Now that you have this saw under your belt, when you go back and read porting threads they will make more sense to you. Homeslice.

A push in the right direction....

Stop over thinking this stuff... routers, CNC mills, CAD drawings, lasers, and lathes.... you can do all the port work you need to start out learning with a couple of files and some sandpaper. Yes it can and does get more technical but you gotta learn to crawl before you can run any races at the Olympics.

Stop thinking of the 2 stroke as this complex little engine and start thinking of it as a simple air pump.

Now..... how can you pump more air???

You don't need to do anything radically different just a little here and a little there.

:agree2:

Ya gotta have a place to start from.

C'mon hometowns!

Just thinking a little different...

I'm sure when you were a greenhorn you were just as bad...I'm at least DOING in my 5th month of studying chainsaws What were you doing in the 5th month after you touched a chainsaw for the first time...I want to be radical...like my uncle was...

Do you read? If so, pick up this book. Interesting stuff.

"So there is good news and bad news. The bad news is: people who earn their livings using linear, logical, analytical skills (e.g., computer programmers, engineers, CPA's) may soon find their jobs in jeopardy, if they haven't already. The good news is: anyone can develop the traits upon which both professionals and personal success and fulfillment will depend in the newly dawning Conceptual Age. In A Whole New Mind, Daniel Pink describes a new era beginning to take shape in the global economy. This new economy calls for skills and talents that, historically, have been largely discounted in the workplace--creativity, empathy, intuition, and the ability to link seemingly unrelated objects and events into something new and different."

And yes, my saw still runs and runs stronger...

And don't worry, I'll get it sooner than you think.

"If you always do what you've always done, you will always get what you have always gotten."

Thinking outside the proverbial box is a good thing, without creativity there are no new ideas, but you gotta know where the box is in order to know when you're outside it.

There’s a reason they don't teach algebra in the first grade… without understanding why 2 + 2 = 4 it would all be gibberish.

Learn the baby steps grasshoppa and soon you will run like the cheetah.

This class is over for me...

I couldn't answer you homeslicers...I was too buisy watching the STEELERS WIN #6

Yo poineer, you want some "Mexican Cream" for your popcorn???:greenchainsaw:

The main thing that bother me here is the notion that it's just an accepted part of learning to ruin a cylinder. That need not be the case. If you're willing to read, study others work, ask questions, post pics of what you're doing, and respond to the feedback, then there's no need to ruin a cylinder. But you simply cannot just go into it blind and carelessly. My very first ever port job was on my 260. That's the very saw that was 1st in class at the recent GTG in January. Of course I've been back in that saw a couple times, but it proves a point. I can take that same saw and go cut firewood with it all day. Matter of fact, I just did in December. Don't be afraid to ask for help and show your progress. Hopefully you'll get good constructive criticism and you'll have a successful port job.

All I'm going to say to that is AMEN.

I'm doing just that, I did what troutman told me to do in a personal PM. I still won't post it like he told me too. I'm keeping my honor even though it will help my case here with him. I agree, the number is low, but I used your method.

The jug ruined? It runs better than stock. So go figure?

I've been studying, asking questions, bringing in new ideas etc...and some of you can't take it? I don't know why. But who cares?

We're here for the support and comradship...

It's all good. Fortunately the saw runs strong and I'm sure you've learned a lot for next time.

 

[Tree Sling'r]

It would be interesting to see how many builders actually never degree the saws they port, and port by eye.
I know a couple.

Ya, I agree too, but I screwed up my first cylinder, went too wide, wasn't paying attention and measured wrong. And it was on a 395xp too.

I sent Chevytown a desicription of how I get timing numbers. There are a few ways to do it, they all work. Port Maps work. Whatever method you're comfortable with. Learning to read port numbers, getting accurate squish readings, ect. are just basics. It's like a new carpenter learning to use a tape measure and T-square, but not ready to build a house yet. C-Town, keep working at it. I'll help in any way I can.
