Well here goes. I got my seloc manual, now I know enough to get me in trouble. I have talked about my problem before. Motor is rough at idle, vibrates(bad) at low rpm but seems to run fine at wot, although the fuel numbers I think are a little high. Also a bit smokey. I would like to check cylinders. Do I remove a plug at a time while it is running(shock risk?), or take one off and start it, shut it off etc.. Also the last time I checked it I thought I heard a vacuum leak, now I have my manual I will be able to say where it is coming from. I believe the fuel pressure regulator. Any help would be great. Also the prop seems fine and this seems like a fuel issue. But what do I know.
Thanks
