Homelite chain saw model 27av. (Dies out when given throttle)

But then the saw started to lose power, wouldn't rev fully up. Using a tip I go online, I took out the spark arrestor. Now it starts easily, and runs full power. Now I can go through an 8-inch log in 15 seconds.

There's an exploded view of getting at the spark arrester in the directions that come with the saw. But it's a little tricky reassembling the works after you do it.

Also, w/o a spark arrester, make sure you start the saw outside, and not near any fumes.

Next time you have carb apart, take all rubber/plastic off and soak the metal body in carb cleaner. Then install the rebuild kit instead of using the old parts. I did that to an old Allis saw that runs fine now. Hard diaphram was the problem.

The above is a quote from Madsens web site. EPA pro saws are saws that are approved by Environmental Protection Agency (EPA).

Not sure if this applies to your particular saw, but you might want to check before removing the plastic caps.

You might try using a higher octane fuel. We find that our saws will idle and perform much better. Also make sure the mix you are using is fresh. It is usually recommend mixing only what you can use within six weeks.
