I haven't had ANY smoke coming out of my 140. I changed the plugs with AC 44f, that's what was in it. Installed the Magwire plug wires. Now, when I rev it up, I get blue smoke out the pass. Side. Had none before. The old plugs were gapped between 25 and 32 thousandths... New ones were installed with the shop manuals recommended 35. Any input? Thanks!!
