Scarce 6-10 with original 16" hardnose bar,produced from June 1968 to June 1972.This 4.3 cubic inch/70.5cc lightweight powerhouse packs quite a punch,will pull 32" bar/full chisel chain with authority. Predecessor to my 7-10 Automatic of same displacement,few other different features.The 7-10 changed to a left hand starter & automatic oiler was added. One of the earlier models with yellow air filter cover,later ones were black.
372xp and 390xp.. Not a pic, but you can see they run pretty good 372xp is a tad faster than the 390... But it has a larger carb and is a 2 piece design. . It's made from real Hurricanes and it could probably eliminate global warming!!
