im taking these with my blackberry and for some reason its a pain to load on here. I had a work order from northwest sleeve to have them fixed. I called CP industries that make the cub cylinders and thats who they told me to get a hold of. So I called northwest and set up a work order but hen I ran across a big motor for a good price and bought it this morning. so I dont need this stuff anymore. if I cant get 250 out of them Ill just have them fixed myself
