SS30 Trimmer

I have taken the muffler off, but I do not see the screen that they say could be stopped up. It will not run except on half choke. The carb is very clean. I need help.

Hey there. You need to adjust the two fuel mixture screws on the side of the carb. One is a white knob and one is a red knob there side by side. The white nob is your primary mix. The red is the high speed. Pop both those covers off (white and red nob covers) it may take a little prying with some pliers and a flat head. Under each is the adjustment screw. You will need to back both of them out a turn or two. You'll just have to play with it till you get it right. Back the white one out a few turns first. Then the red one while it is running to get your high speed where it needs to be. I hope this helps.

I had the same experience.

The screen is located at the end of the muffler as mine is held on with three small screws, so no need to remove the muffler. ( my screen was clean, by the way ) I had already taken the carb apart and was soaking it in some lacquer thinner, being mindful not to immerse the yellow plastic choke control as I didn't know how the plastic would react to the solvent.

After soaking, I blew all the ports in the carb out with compressed air and re-assembled it. Somewhere on here it states that the jets for adjustment are special so that only "authorized" techs can adjust them. Using a Dremel, I cut a couple of shallow slots in the ends to the jets, so they could be adjusted just in case the carb cleaning didn't do the trick. (much easier to do this off of the unit and in a vice)

Using new fuel lines, I re-assembled the rest of the unit. It started first pull, yet didn't have any power and died when the throttle was actuated. I then adjusted the H jet out slightly. (my carb has a H and L stamped within proximity to the two jets and by out I mean counter clockwise just a few degrees.)

It runs like a champ! Something about having to buy a new carb really rubs me the wrong way as this trimmer is only 4 yrs old with no real "hard" work on it.
