I want to add another step to the process of fixing the lean running that can be overcome by running slightly choked....
If you clean the Emlusion tube and jet and still have the lean running try the following, or just add it to you carb cleaning steps to cure lean run.
I have seen this 1 other time and was actually no sure that what was done to fixed it until a couple of days ago. Wayne, "Reddog1" and I were attempting to fix his 2000I lean running problem. We took the carb apart and did the common fixes... Put it back together and still had the same problem.
We took the carb apart again and this time we plugged the intake and with a towel we wrapped a cloth around a air nozzle and blew air into the out put end of the carb.. We were attempting to force air back through the tiny ports in the venturi area/ around the throttle butterfly. There are 2 holes that are about .015.... and 3 <> .005 holes in a row about 3/4 in up from the output side of the carb.. Hard to see. You have to open the butterflies to see them.
I think using brake cleaner spray would work better if you can get the nozzle bent and against the holes...
So we cured his lean running... There was something in one of those holes probably the one below the butterflies on the output side of the carb..
