Hello Sydney,

See my responce to your first post about the starting issue, click here.

As for the oil, are you using straight petroleum oil or or synthetic? For breaking in a motor, do not use any type of synthetic oils, even synthetic blends. Using synthetic oils during the breaking period will prevent the piston rings from seating properly, so use straight Dino oil until your motor is fully broken-in.
