The 2025 346xp Porting Thread

[oddsaws]

Gotta be careful doing that in chainsaws with small ports. You can end up sweeping away the direction and fuel can escape out the exhaust port

I agree. This was a good learning experience working in tighter places.

As you can see from the pic I went a little wide making the port sides more rounded that the original square. This wasn’t on purpose

H&L has the Warhawk 346xp kits again. I don't know what their quality is like these days, but they were getting good reviews 5 to 10 years ago.

Anyone try one of these warhawk cylinders recently? Wondering if they are a decent option at all?

I have heard of stuffers on 346 crank. Where do they come from, some other model?

Hi D

Thread '346 stuffers'

Jun 13, 2019

There was a thread here from before I joined without a lot of info. It seems like a straightforward concept so I had planned on building this with a few pics and a vid and reporting on the results. I started into it this morning and thought i should share what i found and gather thoughts. I probably won't have this finished until sometime next week so if all you want to know is "how's it run" come back later. Also, I get a little long winded on these so bear with me.

My local husky shop guy did a 353 with these. I ran it and I wasn't impressed. He likes his aftermarket junk though...

Just got done with my first warhawk cylinder. .040 off base took .038 out of squish and got to .020 squish. Exhaust landed at 106 didn't raise it just widened and blended it, raised transfers to 122 and intake was at 77 widened and flattened it a little to 78 degrees. Cleaned and pointed lowers. Seems to run well need to get it in some wood soon. No plating flaked or had any issues seems ok for $29
