These are my current symptoms: From idle when I go to full throttle it will go up to mabey 5000 Rpm then quickly start to...

    This motor is running great thanks to all of the help from this forum. Was given to me and taken on as a project then an obsession. Can this motor be static timed to spec.

    Can this motor be timed while running?

    This thing works great, in the dark. So how hard are these screens to see if not inside a cabin. Do the screens darken with age or are they just old technology.

    Are all hubs made the same? Bearing / seal question.

    I need to replace the grease seals on my trailer. The bearings and races appear in good condition. Some string got caught up on the axles near the seals and tore the seals up. My spindle measures 1 1/4" so that would be the inside diameter of my seal. The hub has an inside diameter of 2 1/4"...

    On my test trip yesterday I noticed my voltmeter was above the green at about 16 V. It stayed in the green (about 14.5 V) as long as my lights , bilge and bait pump were on. This is a new aftermarket rectifier not OEM. Will this be a problem in the future ? or is 16 volts acceptable?.

    100 HP Mariner 1989 Idle RPM What should it be?

    Having a heck of a time getting my engine down to a low idle. How low should I expect it to idle. At 1000 is runs and shifts OK but that seems a bit high. Lower than that and it backfires and stalls but will start right back up again . Any suggestions? Thanks
