Well the other day I picked up a older model t270 from a old man for 40 bucks. He said that he did yards a while back and that this trimmer was used but it was to heavy for him so he kept it as a back up. I told him that I would take it with out starting it up.. I was taking a chance but for 40 bucks why not??.... well when I got it home and cleaned it up and she started right up. Well the ???? I have is this model has the tickler lever I have never heard nor seen do to me running t231"s. What I would like to know is do I have to pump it before or after I choke the trimmer??? Also what is the lever function??? Or am I dont the whole thing wrong??? I used it all day today and I think I will never go back to the t231 this things I a hoss . Well any information will help guy thanks.
