Any pointers on how to replace reed valves in 1988 70 hp johnson. I have the evinrude/johnson model service manuel, any additional tips would be helpful.
Ought to be pretty straightforward. Why are you replacing them anyway?
When I was trying to get my engine to run right I found that the stock reeds were bowed pretty bad so replaced them with fiberglass reeds from Chris Carson Marine. One thing Chris told me to be sure to do was not to overtighten the screws holding the reeds in place (lest you make them bow up) and to use a drop of loctite on each of those little screws.
Yes, the Chris Carson reeds are even easier to install. They are a little transparent and you don't need to do the try-and-error alignment with the pencil.
My 1989 manual recommends NOT to lap the block surface. A too smooth surface may leave a reed stuck closed after winter storage.

I am having trouble with idle speed, both in gear and just at idle. The FUEL SYSTEM TROUBLE CHECK CHART in the SERVICE MANUAL has intake or leaf plate listed as possible causes. I have done every thing else. I called Chris Carson and ordered a set of SPORT reeds, figured if I was gonna go to all that trouble I would put in some good reeds. Recently purchased rebuilt motor, still working out the kinks.
Good choice. Are you going to have to remove the rubber from your reed blocks and surface them? I went through all that, not too big of a deal, just a little time consuming to get them perfect.

I suspect the manual is talking about steel reeds, not fiberglass. In any case I'd follow Chris' instructions, he's spent a ton of time learning what works and what doesn't work.

Geeze I hope you didn't get it from the same guy that I got my "rebuilt" junker from. What gets me is all these supposedly "rebuilt" engines that need so much work to run right. In my mind calling them "rebuilt" is an out and out lie - throwing a new piston in one cylinder isn't a rebuild, it's a repair.
Wow, Thats what I thought also, but I expected some stuff. The fuel lines were beyond rotten, rebuilt the primer, but not to bad overall but a leak in the intake would not surprise me.
i tell you m8t after i used course grinding paste & refaced them the idle & response on acceleration was tremendous & if i get some money i gonna buy a set of Chris ,s reeds it would go even better , cheers
