Making slow progress on trying to get the engine in my project ready to start. The engine seems to have been new/rebuilt(?) by a previous owner, but the parts attached to the engine seem to be used and a bit random.
Yesterday I checked to see if the heat riser valve was free to move...and it was not.
I read over several threads and learned a lot...but I still have questions.
I used a propane torch to head the areas on both sides of the exhaust manifold where the shaft for the heat riser passes through. I sprayed the visible areas of the shaft with PB Blaster. I tapped on the ends of the shaft with a hammer. I tried to wiggle the shaft with channel locks...but didn't seem to make progress. I do realize that spending an hour on this process may not be nearly enough...but...I figured that I would ask in case there were any hints that folks had figured out that may expedite the process. Is it worth the extra effort to remove the exhaust manifold to make freeing up the heat riser easier?
While I was messing with the hear riser, I noticed that (with no carburetor in place) when I look down into the intake manifold, I see a lot of brown glop. When I poked at it, it seems to be a sort of oily residue. I tried wiping it out with a rag, but quickly realized that it would be present throughout the intake manifold and that I would not be able to reach more than a very small percentage of it. Is this type of glop what one would expect to find in a well used intake manifold? Should I ignore it and figure that it won't cause any harm? If I need to get the glop out of the intake manifold, how should I proceed to do that? Take it to a machine shop and have them clean it out somehow?
Would I be opening up a can of worms if I took off both the intake and exhaust manifolds?
