    Fuel mix seeping from front of v-4 crossflow?

    Couple questions on my latest "build-up". 1987 Johnson 90hp. Good spark, 120lbs on all 4. Timing set good. This was a complete disassemble, rings, cleaning, paint-job and anything that needed attention. 1) Somewhat rough running at idle, and at elevated RPM's. No sneezing-just a bit shakey...
