[QUOTE="montff77, post: 219320, member: 6743"] This is @ pappy. Hi, I'm new here and this is my first entry. I'm interested in further details on squaring the ports and blending the transfer area on an 64 Johnson 18hp. I can handle shaving the head .060 and as far as extending the reed stops, it seems that this was the only difference between the 18 and 20 HP models? So that should be a 2hp gain alone. Also what HP increase would u "reckon" the shaved head would bring and how much harder is it to pull start. I am hoping your still active on here bc I'm lost without some insight from someone who knows..... Thank you much... [/QUOTE]
