I don’t know if you have this parts book – but it comes in handy some times . . .
Leaking around the cylinders is not normal. It indicates a warped crank case or blown gasket from loose cylinder nuts. The gasket is very thin. We used unbleached butcher paper. Checking the cylinders for high spots is easy. Checking the crankcase will require complete disassembly. Leaks at the base can usually be fixed with a new (heavier) gasket on the driveshaft housing. The dripping from the primer would indicate check valve leakage and/or improper check valve bumper clearance. OR the float level could be too high. That is covered in these service manual pages . . .
