Dont forget to try a shop vac and string uf the tape doesnt work. I dismissed it at first but after trying to fish around a 90 degree bend for iver an hour, i decided to give the string and vac method a try. I didnt think it would work, so wasnt expecting much. To my surprise it took me longer to get the string and vac than it did to get it thru the tower. I have the 6.5hp version, not sure if the results are different on smaller/larger versions.
