Thanks for the advice. I think my snapper dealer will know the model. Years ago I went to Homelite training, back when they made a good product anyway bar oil isnt just plain old oil and I figured oil is oil well bar oil is sticky, put some on your fingers press them together and it is stringy sort of sticky, made this way to travel with the chain as it goes around the bar plain oil just flies off the end of the bar, interesting said it because it was mentioned no real content for the problem just a tidbit
