Thanks guys! After setting carb a little leaner it seems to not be as bad. Saw runs well and starts easily. I was cutting white oak tops pushed into a pile with a dozer and that was very dangerous. You couldn't tell how limbs were stressed till it was too late. I pinched bar like 4 times on...

I have a new(5 tanks of gas)Echo 4910 all stock except MM to near 100percent. Problem is I cleaned air filter today and it had fuel stains on it. It was very dirty as was entire carb and box. Saw is running great. Should I be concerned? What would cause this? Saw was set quite rich. I have...

I have a 357/59 that needs attention so I'm watching this

Echo is around 5 3/4hp and 3.2 torque ported, I think.

I can't find it. I'm not sure now I didn't throw it away. That's not like me though so it might turn up someday. I will try to clean off my bench soon.

Ok I'm wondering about trans port lengths. This design being very short and able to move a short column of air very fast compared to a bottom of cylinder feed. Has there been a design that consistently yields mobedd,r?

On my çs4910 I measured the ex port, muffler flange, muffler exit hole and exit hole cover. All in square inches@ .43, .68, .38 and cover @.3. after opening it up alot. What am I looking for? No restrictions? I expect to make ex port much larger eventually but for now what is common practice?

Ever sell this?

I might have a set. I was sent wrong rings for my 4000 and still have them. On my way to work so I will check tomorrow evening. They were too small for 4000.

I need to take .02 off cylinder base and see where I'm at. Best I can tell right now is 103, 123, 70. .04. It's hard to repeat numbers as lighting and wheel replacement changes along with my technique. ? Is 70 too low? I'm thinking it will be close to 104, 124(or less), and what ever is...

Nothing new since last summer? I guess they are putting 359 carbs on 346,s so swapping a carb to a 4910 is just keeping them even.

I'm working on a 350 so I was wanting some responses to op. Farminkarman, what do you consider a low exhaust? I'm new to this also.

Must be everyone switched to 4910,s

More comparing and more questions. The am intake is bigger and exhaust is smaller than husky but the transfers were the reason I ordered the piston and wanted to use husky cylinder. Husky trans ports are alot wider than AM but the piston blocks off the lower half of husky port and am trans...
