I am going to have to respectfully disagree with you here. When that accelerator pump circuit goes bad, the fuel mixture goes lean/rich at random, from idle to WOT. It causes the operator to chase the tune up and down, over and over, until they finally give up.
Sometimes you will get it tuned out, then after you run it for awhile, the thing goes lean at WOT. So you fatten it up and it runs good for awhile, then all of a sudden, it running rich again. That's why this problem drives guys nuts.
I will agree with you though, when the accelerator pump circuit is operating PROPERLY, it only effects idle/off-idle response.

it looks clean on the other side (with 4 screws)
welch plug comes to a point and is attached to the rocker with spring
there was some white plastic material attached to the gasket, it must be some locktight or some kind of glue used to hold on the gasket.
could this little bit of material have prevented the rocker from moving and caused this issue. I can't run the saw until later to respect people that are sleeping.
the acc pump only affects the saw at an idle
this is not the op's problem
sounds more like it's out of time
pull the flywheel and check the key
is the piston scored?
is your fuel fresh?
is it flooding?
the impulse line is connected and looks good, under the left side of the air filter
Run it in the house like everybody else.I can't run the saw until later to respect people that are sleeping.
I don't have a carb to replace it with, I will go buy one if that will solve this issue. If I have a C1Q-S61 Carb, what should I replace it with ? And where can I buy it ?
Its a real pain in the butt to get started but when it does start it will stay running as long as I keep the throttle open.
When I started it today, it zipped up to full speed for a minute then it died.
Then back to laboring sound as it pulsated.
I held a branch up to the chain and it was able to cut it. So there is power. Not full power.
I have a C1Q-S61 Carburetor.
I did remove the Inlet needle 4116 121 5100 and the control lever to inspect, the needle looked new, and the hole below it had nothing stuck inside, I used carb cleaner and put it all back together.
Before I try to help the inlet needle (welch plug ?) seal by putting fingernail polish on the end, how do I inspect the impulse line ? I can't find the part number or the location of it on the schematic.
