Husky 390xp - Removing carb limiter caps

[Colonel428]

So I've added an extra exhaust port with deflector on one side of my 390 muffler and am going to add another one to the opposite side as well. Both opening are approximately 1.5"x 1" each. I'm thinking I may need to remove the limiter caps to properly tune it afterwards. How do I go about removing them? And please be as specific as possible. I run saws, I don't work on 'em. Thanks, Steve.

I simply use a splined carb screwdriver tool. They can be had for cheap on eBay.

To delete them without the tool, you have to push in the thin spring-loaded limiter ring that encircles the needle screw, as you turn the screw. With the needle removed, you can mod the limiter piece or put the needle back in without it.

I use a drywall screw with the point ground off, so it gets a good bite without hitting the adjustment screw underneath.
Then I just yank.

Thanks Andy. I've got a splined tool and have used to adjust the carburetor already. So if using the splined tool there is no need to remove the caps? Correct? Thank you, Steve.

Totally different type of limiter on the 390, no plastic caps, that won't work at all.

No real need, other than to mod/remove the limiter to allow the use of just a regular screwdriver.

No need to modify on these Husqys. The tool is still readily available and cheap.

This. If you have the tool you can open the jets up as much as needed.
