Walbro WHG

Hi All,

 

I bought Kohler rebuild kit # 25 757 11-S.  I had a couple of questions as there are extra parts than this Walbro WHG takes (two float needles and gaskets not used on this carb). 

• It came with two intake valves (one with a spring).  I used the one without spring that looked like the one I took out.  However the float pin was not in the kit, just the needle.  Is this what others have found?
• Also, there was the thick gasket to go against the block and a regular thinner one of the same size.  I used them both as the diagram showed both (thick one against block and thinner one between thick one and carb).  Is this correct?   
•  The manual I downloaded for the M16 shows a Kohler carb and initial setting for both fuel needles at 2 1/2 turns out.  Is that the same for this Walbro?
• Also I cleaned everything I could without removing the Welch plugs.  
• I am asking as it is running much worse than before I cleaned it!!  Total surprise as I have rebuilt several other carbs in the past and never had that happen.  I am hoping that the new float needle is stuck and/or the thin wire I used on the main jet was short and did not get everything?  It was dirty and needed a good cleaning so surprised at the poor performance once cleaned.  Any suggestions?

Thanks!

If it runs don't worry about the initial settings. That is all they are to make it run. You must adjust the mixtures after the engine is hot for best performance.

I did let it warm up for 6-7 minutes and tried to adjust.  It would seem to get a bit better but only a bit.  Just was not responding very much to adjustments.  That is what made me think the inlet valve was sticking or the main jet plugged some still.
