Is there anything published of this purchase of Zama?
Stephen, have you removed the screen baffle out of the muffler yet? They clog up and will cause the symptoms you describe. Look at the muffler outlet and remove the hex screw there near the bottom right. It's holding down a little tab that you can grab using needlenose pliers or a small screwdriver. Pull that baffle out and throw it away. Then start the saw and see how it runs.
The shops are required to put the spark arrestor back in, but if you 'lose' it the saw will run better. And if you're too paranoid to run the saw without it then I can't help you. It's a stupid, unenforcable rule that should not apply to a top handle climbing saw but Government doesn't make that distinction. They throw everything under the same broad classification with no consideration to the actual application.
Switching to premium can eliminate a lot of problems. Not due to the higher octane, but rather the lack of ethanol in premium gas. Ethanol is highly corrosive and destroys rubber carb components as well as fuel lines.
I have been using medium grade, been advised the premium is too high an octane for the equipment and will burn it up.
CurSedVoyce;253780 Also switched to synthetic mix for cooler running. Not the Echo mix though.. Makes fiber glass with certain fuels. I use Stihl mix only.[/QUOTE said:Sthil, Echo, Poulan, I bet they are all the same mixes. For sure, Echo, Husky and Stihl premium mixes are all fine to use.
I don't use 'synthetic' for anything. Lots of guys swear by synthetic oils, but I really don't see a profound difference in longevity between the two.
No shit? Thanks for the education, Brian. Did the rest of ya'll know this?
Brushers might be an issue though as they 8 hours a day 5 months a year. 5-6 day weeks.
Uhh, I disagree. I run fs250s & fs550s, not to mention hedge trimmers, gas drills, power pruners, etc. etc. For years on premium gas.
How did you get that silly notion in your head anyway? I bet someone told you who is too cheap to buy premium so used that as an excuse.
Of the literally thousands of tree guys I have spoken to over the years, and hundreds of dealers, not one has ever said this. EXCEPT for guys wanting to save a penny here and there.
The expression is called: 'stepping over dollars to pick up cents'.
Here ya go!
Google is your best friend, typical lazy americans!
