Any Chinese chainsaw and chinese parts discussion

[Czed]

No doubt cabers or oem is better but these have worked fine for me.

I'm not so sure that a premium ring is always best. I've seen what happens when improper ring coating combos go together. I like a ring to seat quick and easy and will trade a little life to have it. I've ran some cheap wsm rings in my mod skis that had perfect end gap after the pistons were collapsed. And weisco rings that were junk and pistons were too. But those engines are maxed out and I fully expect to redo them every winter.

Got the newest big bore tuned in wood found another Oregon 20 inch bar and a new chinese chain.
It's actually the strongest one yet it powers through great when hard pushing while cutting.
I need to number them they are visually identical except for bars.

I've got another big bore on order for the fourth saw these have been really fun to build and run
I will try to cut this weekend it's turkey season so i haven't been pissing the hunter's off this week
One got a 24 pounder.

Have you ran a 28 on one of these saws just to see how they do Dave

I'm down to 24 inch bars my longer bars were stolen from my old place
I just make do with the 24 when needed been dropping mostly 18-20 inch dead ash lately so I've got 20s on two saws and a 24 on a big bore.
Tell me if you need a cylinder to practice grinding on I've got those hls i don't need.

I'm wondering if I should just build the kit the way it comes or should I put better bearings in it. I think I might order that big bore kit, you can't beat the price. How much did you have to mess with the big bore cylinder?

Literally just cut the ring off cleaned intake and widened the exhaust a little polished the port edge's so there was no sharpness to hang a ring that's it 30 minutes lol

Better order now two weeks plus delivery sometimes
.80 below the base i forgot to type still haven't got my oem wristpin bearings
I will just been buying too much lately lol

I wonder witch boat will show up first lol.

Those huztl 50mm are good runner's you might do the same to it and be happy .
but i need torque the first saw runs great i'm only going to change out wristpin bearings in all my saws.

Are any of your cylinders 48mm? Stock 365 closed lort

All four were the early design open port 365 style.
odd really they must have a bunch they couldn't sell.

Did you build a big bore 372 if it was you hows it running?

Not a big bore. It was a 372 xtorq. I went with an AM 50mm 372xp cylinder with a meteor piston. Non strato

 

[huskihl]

I used it earlier in the week cutting maple. Burned 4 or 5 tanks through it. Runs good

I think that is just the design they are copying. Mine was also an open port 365 and I got it around 5-6 years ago. Get 'em while they're cheap!

If you can find a Zama twin jet carb to mod for the big bore, I think you will be surprised at the improved torque. I can't believe they are no longer making those carbs. On my 029/390 I tried a modded 460 carb, a modded HD-5 and ended up with a Zama that I put together. It just a better carb; start, idle, acceleration, mid-range and top-end. Perhaps not as much torque below 7,000 as the modded HD-5, but I don't cut in that range anyway.

Thanks Still looking haven't come across a twin jet i'm going to buy a couple carbs from different sources might find something similar you would think there is a zama copy some where.

I've been looking at these tillostson carbs for a 365 and there is also a zama on ebay or the hd12s do you have any experience with those terry syd.

If someone has a HD-12 to open up and take a picture of the wetside (where the needle is), I might have an idea about whether it would be a good carb to do some mods on. What we are looking for is an auxiliary jet in the low speed circuit. The carb you have does not have an auxiliary jet for the low speed circuit.

Here's the difference in your carb and the Zama twin jet. When you tweak the idle on the stock carb, you are also changing the transition circuit mixture and the total fuel flow to the low speed circuit. The low speed needle changes EVERYTHING in the low speed circuit.

The twin jet has two jets, one on each side of the welch plug. One jet is for the idle/transition circuit and the other jet is an auxiliary jet that can be tweaked to increase the total fuel flow of the low speed circuit. ALSO, the idle mixture screw is just that, it changes the idle mixture and nothing else. It takes its fuel off of the idle/transition jet. On the Zama, all three functions in the low speed circuit (idle, transition, total flow) can be tuned SEPARATELY. It makes the carb a lot easier to tune the way you want it.

Perhaps the HD-12 has an auxiliary jet for the slow speed circuit. If so, then it will make it easier to tweak the carb.
