Just another junk chainsaw

[xyz123]

Optical illusion. I would have swore the white one opening was smaller. But measured both same.

I was ready to open it up too.

 

[xyz123]

No ported saws are not needed. Just buy next size up.

But then again you just never know when they come in handy.

Morning Laugh in my chainsaw repair group.

IMHO if you dont have a issues with fines on stock air filter running the o-ring like I do. Not worth it to me.

Echo 490 that I took on trade years ago. It was hack ported no squish or base cut. Running stock air filter with oring.

Then running echo parts Joe showed using years back.
Total cost $30 shipped to me for the 3 oem echo parts.

I don’t have issues with fines for over 2 years now just by running the o-ring in stock.

I swear I can see the playboy bunny in the test wood from yesterday.

23RS newer nk about half wore back touched up.

Retuned for next try. Noticed it had picked up rpm's before last test session with switch. The 490 500 dont like higher rpm's the way 501 4910 can compared to those.


Just trying the $30 set up for fun on my 490.
Might try on one of my higher revving 501’s later.
I ended up fattening it up a 1/4 turn on H side to bring it down some.
10.75 Down, 11 across. Was 1/4"+ down cut shorter then test day before.

But did get both on video.

Since I added the more open exhaust (did not remove the muffler insides yet) and retuned it, it feels more robust and bogs less. I never had fines problems in the exhaust so far.
That air filter looks cool, but I would be afraid of damaging it in the field.

Some guys have fines get by the intake side where air filter mount. The o-ring I showed stops that. Also can use some grease along with or maybe by itself.

Ya I thought about that too. I would only use it bucking.

If you wanted something like this for all uses, you could always by that A2D design one the guy sells. 3D printed with wedge so you can run top cover. But looks like a humpback camel.
You can get it with or without the wedge holes in it. Just not worth it to me, unless you had a really hot ported one to make use of that flow.


I would have prob had that all torn off dropping those 5 maples in March.

Once when stuck and ran and when I got it knocked out of my hands when I got my ribs broke.

I'll be leaving my 2 501's stock set up though. I still havent even went in and opened the intake up yet on either of those. Small gains there shown on Joe's dyno.

With the other echo set. I ended up fattening it up a 1/4 turn on H side to bring it down some.

Can you suggest a "porting specialist" for a Husky 346XP.

I've got a brace of 50cc saws and would like to see one of them "sparkle"/

If I had a port layout, I could do it myself, that is, I have the equipment , Measurment tools , pencile grinder etc, tools and ability. I just do NOT have the experience with numbers that work.

I have a list in my group.

Few I would use myself for a 346 to get a sweet work saw.

But wait time can be months for the good guys.

Better guys cut base and squish then set porting numbers to your uses.

 

[xyz123]

Kevin in MI does a mean 346. But his wait time is in the months. He is that good.

Joe is a good one too.

Thank you for the suggestions.

@CalG Joe even does utube video's with his dyno and shows gains on work saws and some race builds c too.

Now remember there is 2 346. OE 45cc and NE 50cc

 

[xyz123]

Just started to watch. So no clue on outcome.

 

[xyz123]

Never know what the wife will bring home from hobby lobby.

 

[xyz123]

Thanks to E. for leading the horse to water. 3120 carbs.

The aftermarket WG to buy.

Not those other ones that use HT inside.

Then if needing H just have one of the trusted guys do it in these WG ones or oem one.

Not worth buying the aftermarket H side WG fakes with HT one by neojunk.

I made up a replacement exhaust port gasket to fit in where the original had gone missing on the old ProMac 10-10s/ It's a fiddly bit, just a rectangle of material only 1 3/8" on the long side, and a large rectangular hole on the inside. A little picture frame, not even any bolt holes the gasket fits in a recess between some raised ribs cast into the cylinder boss. I should have captured a picture, but...that's not me.

I used soft copper sheet, cut out with a sharp chisel, using the vise jaws as a guide. A fine rat tail file provided clean up. I didn't take the air shrouds off, So the fit was observed through a couple of fastener access holes in the sheet metal shrouds. I think I got pretty close to good.!

Tomorrow I'll gas up and see if it's a go. It usually just takes a squirt of fuel in the carb to get it to pop!
