I'm bringing back to life the P650 is the most finished toaster I have, the piston is notched and it still pumps 9 bar, it must be enough. I made two manifold gaskets in front of the carburetor, I lowered the valve lever in the carburetor because it was flooding the saw. The holes in the spur are so big that I put in 7mm bolts. I changed the clutch because someone put on two shoes is definitely not enough so I borrowed a full clutch from a 50-year-old R18. It was put on the strainer on the oil line and add the rest of the parts. The starter is also borrowed from a black shipwreck ;-)
