I am currently working on a rebuilt Evinrude 18 hp Fastwin and its a 1967 model. It runs like a dream at high speed but spurts and misses terribly at low speed idle in gear and in neutral. I have preset the low speed needle to 3/4 turn per the service manual. It still misses badly no matter what needle setting I use within a reasonable range. I checked the packing gaskets around the needle and they look good so I don't think air is bleeding in, and I assume that the timing cam and roller should be just between the two marks on the cam at idle? Is this correct? It smooths out nicely at medium to high speed but medium speed is too much rpm to shift into gear. If I get the rpm low enough to safely shift it sputters and misses and dies most of the time if I'm not quick enough to increase the throttle. Any advice or thoughts would be much appreciated! Thank you in advance!
