    Replacing Alpha Gen 2 upper and lower housings

    My upper and lower housings are starting to see major corrosion. The gearset and bearings are in excellent shape, so I'm going to switch all internals over into new housings. If all original bearings and gears will be reused, will I need to measure and reshim? Thanks.

    Tearing my hair out with this one. Oil is draining out of the overflow tube into the intake manifold. This seems to happen with the key off and no +12 volts to the remote tank pump. Has anyone experienced any sort of siphoning issues with the engine mounted tank?

    I've been reading up on the link and sync procedure. The way the throttle is currently set on this motor, the throttle pickup on the top carb is making contact with the cam at idle, cracking the throttle plates open a bit. Should the cam be pushed completely away to where it does not make...

    Permatex No. 2 sealant - is this suitable for crankcase halves? 1985 75HP

    Democrats have been in control of the city for 60 some years. And now look at what happened. No planning and no serious leadership. Look at how many poor and gangs and criminals have grown there over 60 years. The democrats didn't do anything to help these people get out of their situation...
