026 carb/choke issue

Are you missing this spring? It will hold the choke closed alone with the master switch.

The spring is there I will check tonight to make sure everything is correct with it.

i think trigger is the same but i think the 034 control is wider

I just cross referenced the IPL's. The both have the same part number for both saws. They should fit, I hope so.

The spring and the tension on the master switch are critical.

So tonight I get home and pull the old throttle trigger and master switch out of the saw, I can't tell that their worn at all.

I go ahead and put the parts I salvaged off the scrap 034 on the saw and they display the same thing, butterfly is fully closed in the lower 2 positions of the switch. In a fit of frustration I took a pair of pliers to the metal connecting rod as it was the only way I could figure to get any slack out of the linkage. What do you know, after 2 slight bends of the rod I put it back in and the saw ran perfectly! The saw was still cold at this point so I choked it, pulled 3 times and got a pop, moved it to fast idle and the saw took off. Now I have an 026 that runs like a raped ape and has a cool retro red trigger.

I really wish that I knew where the slop was coming from that caused this issue in the first place but either way I am happy to have this project complete. Thanks for all the help and advice you guys provided.

I think the slop is in the pivot pin in the trigger or in the handle

Good to hear that you figured it out and that the saw runs well.

I'm glad you got it going.

Just out of curiosity, does your saw have a carb with only a L adjustment, or does it have both the H and L adjustment?
What kind of carb has only the L adjustment? Compensating carb?

I have several of the single adjustment carbs. I think they are all Walbro carbs. Every time one shows up, I replace it with a fully adjustable carb.

Both high and low

Yup. Walbro WT 403A. Just the L and the LA screws. WT 194 has both the H and L and LA.

Check the connection between the throttle rod and the carb lever. It is hard to see in there and I believe that there is a small hole in the carb lever that the rod has to snake through. Once this is correct and the rod is not bent everything should work as intended.

As a check squeeze the trigger and engage the choke. Raise the control lever up one notch. squeeze the trigger again. You should hear a snap indicating that the throttle linkage has returned to the normal idle position.
