Re: Frank A - Can you answer a quick shock mount replacement question?
Keep the engine vertical. Do not support the engine with the lift cylinder because you will need to pull out on the leg to get enough room to free the shock mount. It is held on with the four bolts that go through the kingpin cover, and four more bolts that hold it to the midleg. In order to get enough room to get a wrench in there then drop the mount, you must unscrew the two bolts under the front cover holding the "hockey puck" mounts. Then you must lift and tilt the engine forward in the lower pan. (support plate) Be careful because it will rest on the carbs and plastic covers. As long as you don't bang it around, they will take the weight. WD or PB the hell out of the bolts especially the ones holding the mount to the midleg. They are almost always corroded and tight. Disconnecting the shift and throttle cables at the engine is a good idea but nothing else needs to be disconnected or removed.
Don't worry about the kingpin--It is usually relatively tight and will not fall out. And there is too much interference for the engine to fall out of the lower pan. Most of the kingpins I've played with needed to be driven out of the support plate.
The bolts that hold the mount to the midleg are in slots in the engine mount so you really only need to remove two on one side and loosen the other two, but it is better to remove them all and re-install with plenty of anti-seize.
Putting in the new mount is easy, but re-positioning the engine is not so easy and may take several tries before the hockey pucks will set into their respective slots in the front swivel mount. (Front leg cover) Way easier if you have someone to help you. Replace those carbon steel bolts with stainless.
If you have never done it before, figure 1 1/2 to 2 hours. Once you have done it and know the order--probably 45 minutes. Not really a big job. Main problem is with tight bolts. Have fun
Oh yeah, I forgot to mention: You may need to wedge in a couple of tire irons or crowbars to move the midleg away from the front support plate down by the mount.
