Ok so long story short. Been having a hard time figuring out why my engine started smoking and running horrible. After compression tests...visual of valve seals ....new pcv and filter....and carb rebuild...ive finally gor it running without smoke and going smooth. Havent drove it yet. Seems blowing air through all the holes helped something. No smoke...90% smooth idle now. Question is...when I look down the carb...I dont see any fuel being dumped in. Even if I raise the rpm a little I still dont see anything. Am I supposed to see something? I'm wondering if I dont have one more hole that's stopped up. What is the copper coloered pipe sticking out the carb neck? And should fuel be coming out of that? Not the big one up top but the little one in the bottom part. As for seeing fuel do I need to hit some major rpms to see that? Just want to be sure I'm still not clogged somewhere so I dont get stranded on the road.
