Running rich

<< < (2/2)

77cruiser:
If it was down it would be lean, but if it was up then it would be rich. Only way to check would be to take it apart.
You can use a small screwdriver to push down on the hanger through the vent to see if it's moving up & down.

455man:
The top has been off many times changing rods/jets.  I can take it off again and look.  It's moving up and down.  Would it look obviously bent or is .010 enough to make it run too rich?   Are you thinking the rod/jet combo should not run rich? 
I disconnected the accelerator pump to see if that made a difference. It still ran rich and as long as i eased in to the throttle it ran fine.  No lean spots like i would expect.

455 . i used to rebuild carbs just like the one you working on. gasket kit and misc. i ended up with the same results . they never ran the way i wanted them to . the last one i did with over the counter kit with (ethanol resistant ) acc. pump.didnt make it 20. miles and the cup swelled and came off the rod. the only way i will do it today is totally strip, install shaft bushing ,new pulloff, and anything else thats wore. and the end results are awsome. it may take you a while to get to that stage of the game but the results speak for them selves . ive found that most have bent hangers and worn out needles. unless you have all the measuring tools its hard to see the wear. fwiw
