Removing carbon deposits?

NO NO NO!!! You must not use duct tape, as it scares the gnomes away. Nylon zip ties only.

After cleaning, I would suggest that you consider changing the brand or type oil you are using.
I have two stroke saws, trimmers and blowers that are at least 12 years old and have never had a carbon problem:thumbsup:
Most of them are Echo and I use their oil.
