2084 super cub running lean
i bought a 2084 super last fall that needed some work i've got most of it taken care of but it's running lean [if i close the choke about halfway it runs pretty good] i know they make different jets to change the mixture but i have'nt been able to find the specs to see what jet size is correct.i'm not sure if my carb is the right one [could be for a smaller engine i know it's been worked on because the fuel selenoid plunger stem has been cut off ,selenoid does'nt work]does anyone have carb #'s and specs for a 2084... thanks dale

Re: 2084 super cub running lean
Sounds like you have a very tiny piece of crud in the jet. Does not take much to effect the fuel. Had a 2072 that I rebuilt the carb. Ran great and all of a sudden it would not run without the choke out about 2/3rds. Took carb apart and found a tiny piece of crud in the jet. Cleaned it real good and it still is running today like brand new.

Re: 2084 super cub running lean
i've had the carb apart twice now and blew it all out ,i just got a new carb and checked the jet size it's a 150 just like mine but i found a o-ring under the fuel selenoid that my original carb does'nt have i think that is letting it suck some air around the selenoid i hope.

The carb on my TroyBilt had that problem, caused but a rusty gastank. I never did get the crud out of it, I finally bought a brand new Carb and fixed it.

Re: 2084 super cub running lean
well i got it fixed,installed the o-ring that was missing still did'nt run right,installed brand new carb that i bought still no good,drilled the main jet from my old carb out with a 1/64 drill bit[did'nt take much]now it runs good as long as i'm working it a little ,pulses a tiny bit at idle got to play with air screw to see if that will fix it

Re: 2084 super cub running lean
Dale ,I had a command here that had been sitting a while ,pulled the carb and cleaned ,didn`t look bad at all.stuck i back on and no better. did it again and same cond. I called a guy that used to work for me that now works at a toro deale and he stopped after work and ripped it apart again and blew air,carb spray put it together and same,he did it once more and got it and I had no more problems. He said it only takes a tine chunk ,not as forgiving as the older stuff.

Re: 2084 super cub running lean
My 582 was doing that, mostly on low idle, and trash in the welch plug. If you have fuel lines that are going bad, youll be fighting it a long time!

I havent, but when I worked with Frank, the engineers at 3 schools told us it was killing them. I am working on a 12 now that was in a 100 and the gas looks like green cool aid. I dont have a clue what to do. Ive also noticed at the truck stops more and more tags on the pumps about low sulfer fuel.
Damn Al Gore LOL
