Doing that nice red 3.7 61cc thin rings saw.
Just so new guys see tank vent style oem. Pull to the top inside tank. I use oem echo 3x5.

New fuel line, fuel filter, plug. Fires runs and stops. Time to replace those stiff diaphragms IMO.

Going back through everything. I caught a mistake I made yesterday.  61cc thin rings 3.7.
I installed the wrong Walbro fuel filter. The small one for 30cc under stuff. I put right one on today and she starts and idles fine.
I’m wondering also if setting over night with my fresh efree mix might have help dias some too. No clue but great now.
Least now I got a new batch of carb kits on order for these now too.
But has anyone seen just a wrong size fuel filter do something like this before?

Video on CR FB running perfect now.

Auto oiler works great too. 😎
