My 1975 25 Johnson starts on the first pull and runs great at full speed. Problem is that it's running slightly rough at idle and when throttling-up from fast idle to full speed it bucks really badly. It does the same thing when throttling back down to fast idle speed. Once at fast idle it runs relatively smoothly but doesn?t jump up or down in RPM like it does going from mid to high speed. Any suggestions would be appreciated. Thanks! Doug
