I like it.

Are you going to make a new head?

I will make a new head only if the one that's in the lathe won't work out. I want it to fit under the covers.......Bob
Thanks for showing the picture!

just when i thought i was nuts with the lame thing some has to kick it up a notch..
i forgot, i was going to check today if a huskey 140 piston was taller

When you guys make a two piece cylinder it for a hight compression ratio right?? And do you always split it at the top where the ring wont travel?? And Have you ever taken it out near the bottom? I see you cant shave the bottom because the clam shell design, but ever cut a section out below the intake port?? Sorry for all the questions guys just VERY interested.

And what do you do to seal it???

Correct.

And do you always split it at the top where the ring wont travel??

Yes.

And Have you ever taken it out near the bottom? I see you cant shave the bottom because the clam shell design, but ever cut a section out below the intake port??

You can't with this design like you said, and it's not practical to cut part of the middle out.

Sorry for all the questions guys just VERY interested.

And what do you do to seal it???

You can make your own gasket or use liquid gasket maker.

i have a qustion of my own, after porting (the frist time) it would idle perfectly and smoked like hell tried leaning it out some but it would just die..
but at WOT it runs like a raped ape.. (no affiance randy..)

i'm keeping an eye on the 2 piece head that just seems nuts

it sucks the only thing i've been able to do the hog is idle it in the bast two days..

 

[MechanicMatt]

What kind of sealant do you guys use to seal the two halves back together?? I talked my nephew into keeping my little poulan and giving back my 026, so all I was able to do to it was a Muffler Mod. I gave it a smiley face mod, he liked it. I was just wondering about the sealant, looked black. RTV????

 

[ckelp]

i used red RTV if i blow it apart again, it's going to get caterpillar joint compound #2 used it once and love it

is this thread ever going to die??
i think we should start a new one because it's not about the GTG anymore

I use Permatex Moto-Seal, great stuff and inexpensive too!

Start a NEW one?
Heck! GTG season is just starting again!!!
Be a shame to lose all this great info......or have to repeat it again.

Well, there goes the neighborhood.....GREAT JOB

so i findley had time to put the tame thing to some wood and i think i smoked the bore with my "port job" it revs nice and it sounds good but it feels like something holding it back am i going just have to step up to a bigger carb? i'm planing on puting a tuned pipe on it if it's not smoked..

I've only stepped up to a larger carb on a few saws. Most port jobs don't require it. Any way you could post a video???

 

[ckelp]

not reilly, this week i'm going out of town on business.
i may have time on Wednesday to take it out if it dose't rain...

 

[epicklein22]

If someone is looking for one of these saws, my buddy has a 2075 for sale. Looks good and he says it runs fine. I'm gonna clean it and up and sell it for him. PM me if your looking for one of these, otherwise I'm just gonna sell it locally.

Thanks for straightening that out Mike. :msp_laugh:

Hey, this isn't much about the WhiteTrash we all love to trash, but it is about something that we all like. It's called a GTG...:hmm3grin2orange:

I found this a couple days ago and when I SAW it, I thought, hey a GTG. Let's rock

He won't need a description of the thief now, will he?

I busted the intake on my wildthing just a few days before the west ky gtg changing the carb. I didn't get to take it and dominate the 40cc class in the cant race.

Well that gave me an excuse to go back in looking for MORE POWER!!!!!!

I had .035 squish, on a saw this small I like to get it down to .020 But the wildthing is a clamshell saw, that makes it a bit tougher. I could have a popup welded on to increase compression. I didn't much like that because the piston is plated and the heat from welding could cause it to peel off. The other option is something I've wanted to try for quite a while.

I milled .045 off the bottom of the jug/case.

Here's a shot of the boost ports I added last time I was in here.

After a heck of a setup job on the milling table I used a boring bar to raise and center the crankshaft.

I turned a .035 popup on the piston which left me .020 squish. (batteries died in my camera, I'll get a pic of it tomorrow) I ended up with an intake duration of 162° and I raised the exhaust port up to the same duration. After checking the compression I still had 160 psi!!! I only had 140 psi before I started and the exhaust was just at 145°.

More info on the progress when I get more done, hopefully I'll get a video of it in a day or two.

Nice work Randy! I'm anxious to see how it runs.
