Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

    Picked up a CCR2000E non-starter pretty cheap today.  Took the carb off for a cleaning and got it starting and running well.  But I'm not sure about what the setting should be on carb. 

   The main jet seems fixed but on top is probably a low speed adjust needle.  What is the initial setting for that?

   The Toro parts breakdown does not list the carb number, the carb as an assembly, or the carb body other than "carb body" without a part number.  The engine is a 47pml-5 Suzuki.

I think you may have problem with how you preceive smooth running,  under load the mower engine should smooth out, at idle the mower should sound slightly rough and blubbler a little ( sould like a idleing line trimmer ,old dirt bike or big chainsaw)

I have sold about 100 of these suzuki engine 2 stoke commerial mowers by Toro.  as long as the carb does not leak and the engine does not die (I think it idles about 600 rpm)..   it is fine.

Good Luck,

P.S.  make sure the engine does not surge when idling  or hesitate when throttled up.  Check the shaft, seal and hole for the govener shaft comming through the engine.  they erode bad from grit and dirt from mowing ( they suck air and wear out the adjustment in the linkage)

You're right about the perception problem. I've only messed with a handful of the two stroke snowblower single stages. The issue was trying to get it perfect and not knowing the factory setting for the low idle screw. A low idle screw on a no throttle machine was the weirdness. Since it was a second hand machine and I had taken the carb off and cleaned it I wanted to get the factory settings for a known start. Since posting I asked a few more dealers and they did not know. I did not know if the prior owner had messed with the setting so wondered what the factory called for.

I messed with the low idle setting for a while running it up and down trying to find its limits and one to two turns out seemed to be its range for best running.

It ran well enough. I was just trying to get that last max. The ash as Borat suggested checking was fine.

I have the same carb on my snowblower. Worked great until today. Won't start. I gave it a quick cleaning, and still nothing. I am going to give it a much better cleaning tomorrow. My question is, to the left of the needle valve, in the picture is another screw. The needle valve has a spring on it, the one to the left does not. How tight should the one on the left be tightened?

It is not an adjustment screw and it needs too be snug. It is soft brass and cant be reefed on too hard or it will distort.
It has a very small passage that runs from the tip where it connects with 2 larger passages on the sides.
That passage sometimes needs too be cleared with a very thin wire. When its plugged, surging is the main symptom.

I have a Mr Gasket carburetor needle valve and it's perfectly okay. Don't what settings you want but a pic would be a help.
