hm..., yes, this one must fit tower starter cone (1-13/32), but why on tower site is link from tower starter to sullivan rubber insert with dimension of 1-7/16 (lxbc72 and lxbc73) ???
In my case, and for my work around my hobby and if hobbico and tower starter is same cone dimension (inside) cheap rubber insert is work fine for me. but direct replacement rubber insert for hobbico starter is 1-3/16 outside dimension (lxl401). something here in tower web is wrong, what ?
