Can anyone tell me how to remove my carb from the P218G engine and clean her up?

Don't need to take it off. Just remove cover screws and clean out and blow cleaner through all passages and check float valve. reassemble. Should work great.

Make sure you remove the mixture control screw to completely clean that circuit also. Seen too many of them put back together and still run like crap because they didn't clean that passage out. Of course, you'll probably have to readjust the mixture after you do this.

I just did that on my P218G. Mine was surging at idle/no load. Threads on this site convinced me to pull and clean the carb. Glad I did because it worked.
You'll need a 1/2" crowfoot wrench on a 6" ratchet extension to back out the two bolts threaded upward through the manifold flange into the carb base.
I disassembled the carb and soaked it overnight in carb cleaner dip, the nasty carcinogenic stuff in a gallon can from Autozone. After the soak, I carefully removed all the brass fittings (idle screw, needle seat, jet, slow idle jet, etc) and flushed their passages thoroughly with aerosol carb cleaner. The slow idle jet (roughly 1/8" x 1 1/4") was especially gummed up even though I had run Sea Foam through it.
The main gasket between the two halves of the carb body come out clean and intact so I didn't have to replace that. The gasket between the carb and the manifold had to be scraped off and replaced ($2.50 at local JD shop).
After reinstallation, a little fuel dribbled down through the carb for the first startup brought the P218G back to life and it's been running smooth and strong ever since.
