I have a 1979 175 v6. I am replacing reed block gaskets. The seloc manual talks about a plastic locator. They are also covering all three configurations in a very confusing manor. I have verticle reeds. Is there a plastic locating pin? I don't see one. Should I use gasket sealer on the engine surface and the reed block to locate the gaskets?
 
Sorry, looks like your post got missed here.

If you can't see/find the locating pin it probably isn't there - Merc used many configurations and the picture in the manual will never be what you have in front of you :))).

I wouldn't use a sealer (such as a permatex gasket maker type sealer for engine blocks) on the gaskets - if you want something to "keep them put" grab a hold of some "aviation gasket sealer" (comes in a little bottle with a brush attached to the cap) - just (paint) both sides of the gasket and it will keep them "stuck" in place, without interfering with their function, or creating extra bulk at the joint.
 
I just ran into another problem. I bought a reed block a while back because it looked nearly new. It is from a later model because it had what I believe is an enricher on it. everything lined up good except it has one less bleeder valve at the bottom. "E" I believe. Can I plug the line, or re.route it or do I have to put the old one back on?
 
You can plug the line.

The lines scavenge from the reed cages to feed some oil (oil/gas) to the upper and lower crank bearings. One missing bleed (feed) line is not going to cause any issues - just make sure it's well plugged or that oil that should be going to the bearings will blow out of that open end...
 
You either simply plug it and live without the "feed" into that line OR get a bleed line T connector and tee it into one of the other scavenge points. As long as it's not simply open to the (atmosphere) you can live without the scavenge point - there a bunch of others on this model..
