Getting into a used 046

[NeoTree]

The sound quality just sucks, along with other saws running...
Any leaner on that saw and bad things will happen, we set it pretty good that day.
It truely isn't a race saw and I'd rather it last longer than cut a hair faster anyway.

Great thread i've enjoyed reading through it and looking at all the pics. I'm curious to know what chain you are running on it?

Started porting the cyllinder tonight. My compressor took a dump on me before i could finish, a few things need evened out and made symmetrical.

The piston had a few aluminum micro dingleberries on the crown when I disassembled it, so it's gonna need race gas I suppose.

That thing will be Nasty on Some Sunoco 104 Blue Ha Ha!!!!! heck the 260GT gold is 97,,,, with some Klotz R50 @ 32:1 Heck Yeah!!!!!

You may want to put a new decomp init for cold starts,,,, You'll be breaking starter pawls LOLOLOL!!!!

Yes some signs of Detonation are definitely present,,, It seems we had this discussion,,, JMHO Pump gas is gonna break it!!!

That saw freakin rocks dude,, JJ was right,, it's got some BALLS!!!!

You could always make a thicker gasket and get it below 200 psi for pump gas use!!! but not much below!!! LOLOL!!!

Great work. Just a question, do you weld the popup onto the piston? I have always wondered that. I have never done a mod or popup before due to that I don't own a lathe but curiosity has me thinking I might need to get one.

Thanks, I have read about welding on the piston tops on here, but most of the time for a popup people turn down the top of the stock piston, leaving the popup, and then fallow that up with taking the same amount of material off of the base of the jug to even it out.
This popup was special because the piston I used had nearly all the same specs as the 046 piston, but was .050 taller or so. So all I had to do was cut down the top of it in the shape of the combustion chamber. Since the piston was now the same height, not including the popup, I didn't have to turn the jug base down.

Ya your right, I'm running it on cam2 at 40:1, yes - definately a BIG thanks to JJ for the suggestion! It was a good challenge.

Thanks, I'm just running a stihl full comp chain, square ground-round filed, I think, lol. My hand sharpening skills aren't awesome, but they get me by.

For that hard wood i'd replace the full comp for a semi skip see how you go, i had to change with the hard wood in my new area, just a thought.
