i received my heisler tonight and it did not come with an oil bunker and it did not come with three stacks,it came with two-straight and onion. i lubed it up put it on the track and to my amazment it ran rather good. it has that tik tik tik someone talked about but i dont think its realey a problem. no slow speed surging(low speed is slooooow and steady) real good high speed and nothing brokin from factory or shipping. as far as the tik tik,i found out how to make it stop-i turn the power off! all i need to do now is find a way to move the cuplers up to meet my cars? bob.
