if upon shutting whip down for the day you pulled the throttle trigger several times then stored the whip top of cylinder side down would this help to flood the cylinder with gas over night and in the process help disolve away built up carbon deposits ?

and when taking off muffler in order to get into cylinder and clean out carbon deposits im wondering peoples best methods ?

It is a pretty simple maintenance thing on Echo and yours is probably the same. Take the muffler off and the spark plug out. Use a piece of round wood to clean out the port while blowing air into the spark plug hole. Be sure to set the piston as low as possible. I am not much in using less oil and risk reducing the life of the engine. At about the three year point I pull the head and put in new rings and clean out the ring groves.

Ive been running my echo's for 5 years never had any carbon build up. if you run a 2 cycle at have throttle or less, you will have probs, 3/4 or full no probs, or if you mix gas to rich with oil.

I don't remember having to scrape an exhaust port since my Echo days.

u can put an oz of enzyme mix in it/ i put almost 3 bottles in my boat everytime i fuel it up as it hold over 300 galllons. it eliminates water from the gas and cleans out al that stuff in the motor

Synthetic oil is a must. Think about it, you are not always running at top speed which is the best for the machine but not practical for trimming. If you are running conventional petroleum based oil (at any concentration) you are not burning it completely. Incomplete combustion = carbon. Give yourself the edge and run synthetic (AMSOIL KICKS AZZ) 2 cycle with whatever gas you want. I use 87. You still deal with the incomplete combustion of the gas (which obviously will make a little smoke and carbon) but nowhere near the problems running regular 2 cycle.

You may also want to consider looking at the screens in the exhaust. They are probably plugged and that backpressure also causes problems. A hotter plug sometimes will help too if you really want to start splitting hairs.

Switch to AMSOIL as they all are telling you.

Amsoil is better than Dino oil , but Redmax Aircooled & Snowmobile oil cokes far less, and as a bonus puts out more H.P even if you mix Amsoil leaner.

Tooooo expensive to run all the time........time to clean ports about 5 minutes a year.
