Oh,my bad. 3 or 4 years probably is not enough time to iron it out.
It surely does not have the stutter stumble revbust lean face splatter. lt only happens to a very small percentage of them...hardly noticable really...there nothin wong with them husky carbs....its operator error...did you read the manual's 'how to operate' section? l am kinda sad the nickel did'nt proove that 562's suck. In all honesty Bradley, thank you for doing this thread and having a go we just have to put this one in the R&D

How about husqvarna using stihls compensator carb design , patents eventually expire and become fair game , 550 xps run a walbro aswellDesign patents!
Are you also going to argue that 2-mix and the spring av isn't also bought from husky?
Over here (UK) Stihl will quite happily tell you that it is rented, but they'll also point out that they own zama (but use walbro in the m-tronic carbs) and also the elastostart thing on the t540.
But thank you for the thread brad, we eventually got to the bit I wanted to see

What shall I re-name this project? How about Double Deuce Triple Twenty, i.e. DDTT?

Read all my previous posts carefully, the 2 seem to be sharing a LOT of patents currently. The 555/560 556/562 use zama carbs.
The 550 is still on its first carb design whilst the 60cc saws are on their third! I think that just goes to show the reliability...
And yes, patents expire, but other people can't patent the exact same design shortly after. Global patents also last 10 years, so how have dolmar been able to use either design considering 2008 was the earliest patent I found?

Well, all that aside, it is what it is. I've taken on the task of making it run right, and I'll just have to do whatever I have to do, even if that means buying another carb and the AT service tool.

That's where I am right at this moment on account of the BUM deal I got on my latest 036 Pro. That bloody thing is going to be a basket case for a LONG time!And sometimes we run around in circles skipping and singing loudly. I love those days.

Maybe if you paint the case gray it will make some gains
Im sure this was glanced over with the exciting videos last page.
Ease of manufacture mostly and it lowers the cost of casting the jugs. It also makes the QC process easier, but then it provides yet another potential point for air leaks.
Absolutely. That's one reason the fallers around here liked the big Solo saws back in the late 80's/early 90's.
I also think it makes it easier/cheaper for them to de-tune a saw to meet another price point, i.e. the 555 and 365. Instead of having to develop and stock another P&C, they simply slap on different covers.
I think I am going to get Wiggs to port my AT saws.
