There is a very fine line on the points type 10 series saws .If you get just the right amount of advance they run like a scalded ape .Too much they try to break your wrist .

They don't have a very large starter drum .The little ones like the 10-10 aren't bad but 70 cc and larger just the compression alone can hurt you .

On the oilers though I've had some leakers none really were that bad on this style of pump .Now the diaphragm type impulse pumps on the later PM 610-650 will cause lots of problems .Those will hyraulically lock up a cylinder to the point you can't pull them over . You have to blow the oil out to even get them to roll over .
