OK I did some testing tonight with the 20% and a Cold Plug and this is what I came up with. I set all the factory setting on the needles. Started the engine and it was really fat. I leaned the hsn about 3 hours total and was producing good smoke and it runs great on the top end. So I started on the LSN, all in all I took 8 hours out of the bottom and put 1 back in the top. The motor runs good on the top and will idle. After a count to 5 the motor will rev up nice and fast. Big puffs of smoke on the bottom at the start and a nice small stream when WOT. Thanks for all the help.
