reed valves

[glengold]

Where can I find replacement reed valves? on brp.com they have the entire assembly for sale. Can't I just replace the valves? And are they plastic or metal?

Re: reed valves

Hmmm...What engine are you refering to?? Can't you replace reed valves. yes, of course you can. Usually they are metal, except those that are plastic made by performance folks.

Re: reed valves

Sorry, Its a 1977 55hp evinrude 2cyl. I can't find the oem reeds for sale new, just on ebay. I looked at boyeson, but read on the forum that they are more prone to breaking. Also, I would need to change out both top and bottom cylinder reeds with boyeson if I went that route correct? Thats gonna be expensive! The bottom carb is spitting a lot of fuel so that is why I suspect broken reeds.

Re: reed valves

Did you take the carbs off and actually inspect the reeds? Sometimes a piece of crap can get caught in them and cause this prob.

Re: reed valves

Boobie nailed it. A screw from the airbox came loose and got sucked down the bottom carb, thankfully stopping at the reeds. A pair of needle nose pliers got it and all the reeds look fine. I'm considering some blue locktite on them, as well as the throttle plate screws. I found a loose throttle plate awhile ago and just tightened it up. I know one of those screws wouldn't stop at the reeds.... what do you guys think? maybe the red locktite on the throttle plate screws and blue on the airbox screws. Also, the gasket where the airbox attaches to the front of the carbs is shot, and only two out of six screws are holding the airbox to the carbs, one on each carb. Is that a big deal? I got the motor from a mechanic who said it doesn't matter, and after having one get sucked down the carb I'm all for less screws inside the airbox....

Re: reed valves

The throttle plate screws are normally "steaked" or peened over. If you try to take them out you may screw up the threads in the throttle shaft. Best thing to do is make sure they're tight and leave well enough alone. Put some blue loctite on the screws that hold the airbox on tho', and use loctite primer first. Throw the gasket away that's between the air box and the carbs and the screws will seat better. Glad you found the prob.
