640221 Carbs. Bought new, installed but walked away from it for a long time to work on other stuff. A year later, there was dirt dobbers nest in the small air hole that goes from the front of the carb to the bowl. I busted the dirt, sprayed cab cleaner in it, but couldn't get it cleaned so I blew air through it. Something shot out of it. Don't know if it was the dirt dobber egg, or something that was supposed to be in the carb. The second carb. I cupped my hand over the end, to catch what ever blew out, and it blew through my fingers and got lost as well.
Question is, is there something important in there, that's gonna cause me to just replace both carbs? (the carbs are expensive)
Also, do they make metal bowls for these? All I'm finding are the plastic ones.
Compression is about 120 on each side. I got fire on both coils. but only one cylinder will run using carb cleaner or gas.
Any advice will be appreciated. This is the only 2 cylinder Tecumseh I've ever worked on.
