Dominant saw V4 371 build

[huskihl]

This 365 came with a stupid blue module, so true potential wont be expressed till I swap out to a black module. More money.......more money arggggggg

Can usually find a used 350 coil on eBay for $15

Just give it a 1/8-1/4 turn on the H past the limiter and run it to test before you get the unlimited coil.

Project on hold now. Just found issues with the 371 cylinder I was using. So i checked the cylinder with a flashlight and found scuffing which seemed excessive for the coulple minutes that i did run the saw. Pulled the jug and piston is still fine thankfully, but i found a spot on the intake side of the cylinder wall above the transfer ports that looks like the plating is wore thin. Stuck the ring in the cylinder at that point and you can see a slight gap between the ring and the wall in that spot with a flashlight. Also I ran my fingers along the transfer port bevels and a very small shiny flake was stuck like a sliver in my finger. Bevels were very sharp and rough in spots.

I think my low compression problem is due to a worn out jug that i thought was good. Now just gotta figure out funds for a new cylinder

Glad you found it before ruining that fancy piston. Good catch. Wish I had a cylinder sitting around...

Well with some great help from my local saw buddy, he donated a new 372 p+c to my cause. Thanks William Opelt.
I have been fighting with Celiac disease and just been loosing it all together, loosing weight like crazy and not trying sucks. No energy to hardly even get out of bed at this point, so waiting on gastrointestinolgest to run an endoscopy seems to take forever.
On to the finer points of life, I compared squish with the new jug vs old 371 jug, within .002 so that's great, but also have to use a gasket again. It's slow for me to get anything done at this point so bear with me.

Take note of the cylinder fin difference, 371 jug vs 372

Health first. You can play with garden equipment later. I hope the Docs can get things sorted for you soon. Playing the waiting game sucks.

Thanks much. This health thing has drove me into a bad state of anixety and depression, I find it therapeutic to operate on a saw, it really lifts my spirits.

I totally understand. Tinkering on a saw can be a nice way to release some stress. Let’s you focus on something else for a bit.

Interesting part about all this, according to my buddy willy and my own observations, husqvarna is packaging a single ring piston with all these lower cost P+C kits. What I mean by lower cost is the cylinder kits made after the major price drop. Havent seen a "cheap" as in a 150 dollar factory kit with 2 rings yet.....I want to hear what other folks are finding?
Kit part number 503626473 says fits 362, 365, 371 and 372

I would guess the 372 cylinder has better cooling. Was there any difference in ports or the size of them? Hope you feel better soon sir.

 

[Funky sawman]

Couldn't see any visible difference in port size, or shape. Hard to tell timing, but most noticeable was the chamfer on all the ports was a larger radius

Guy was a trooper, 60+ years old and still out there knocking trees down. RESPECT

@Funky sawman you still need a unlimited coil? If so pm me your information and I will send you one.

 

[Funky sawman]

I'm so tired and and mindless anymore,.
So I got that saw put together, took me 24 hrs, my god so anyways eventhough squish looked good, with a head gasket the popup is hitting the combustion chamber. I'm at a loss on what to do now, the world isn't on my side anymores

 

[Funky sawman]

Atleast I think. I think the popup is hitting the chamber that is, I just dont know, but sumthin is hitting at top dead
