How long has the fuel been in the gas tank that you are smelling right now?

Hi smalltimer, thanks for the reply.
The exhaust odor I smelled (rich), the gas was only 2 weeks older than from when it was running good, with no odor.
I have been storing my mower in the fall, in my shed, since 2009. I put Stabol in the gas every year before storage.
Starts right up in the spring. Battery also removed and kept in my garage on trickle charge.

I just need instructions to set up the carb.

Thanks sb

There is only two adjustments that the user can perform.

• Idle mixture. Set at best speed between too rich and too lean.
• And idle speed which is usually set at 1750 rpms.

Maybe make sure correct spark plugs were installed if changed by the shop also.

Hello...On the idle-mixture screw what is the starting point? OR, how many turns out from fully closed? There are lots of conflicting answers to this question online.
Plug was never changed from the shop.

Thanks

As a rule of thumb I use 1-1/2 turns from seated position. Note on some carburetors these mixture screws have no effect especially on the idle jetted Nikki carbs; unless, the jet is resized.

Thank You so much Star Tech

Are you actually smelling rich out of exhaust? If you pull the plug what color is the insulator? Also check your breather hose that runs from top of gas tank back to the walbro carb. for that will let you smell gas fumes in some cases
