      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Throttle hanging up

Recommended Posts

1998 Johnson 90hp, 4-cylinder, 2-stroke, oil injected.

The engine has been a great performer but recently it has been having trouble idling down. I did a little checking and I noticed that the throttle linkage appears to be hanging up and I have determined which one it is. There are two throttle shafts connected in tandem. I couldn't see anything obvious that would be causing this but I can manually push the linkage down to the idle position. It felt sticky or dirty or something so I lubricated the shaft at all pivot points with WD-40. At first I thought it helped a little but yesterday the problem returned. I checked the screws that hold the throttle plates onto the shaft to make sure they are all tight.

Are there any seals on the throttle shaft that could be needing attention? The only other thing I can think of is that maybe a throttle return spring broke?

Any suggestions?

I would start with disconnecting the throttle cable (try and remove the circlip first and see if you can get it to pop off... if not, disconnect the holder by the finger screws and it should pop off) and make sure that it'll return to idle on it's own first... to isolate control box / throttle cable vs linkage.

I've disconnected all the linkage to the throttles and have narrowed it down to the right one as you look at it from the intake. The cable connects to the left one and then linkage interlocks the right one to the left one. I guess you probably already know that, sorry.

If I manually open the throttle and then slowly let is ease itself back down to the idle position, I can feel a slight resistance just before the throttle gets all the way down to the idle position. I can then manually turn it the way down if I overcome that resistance. If I open the throttle and then let it return on its own spring tension, it snaps all the way back to idle position.

I believe I found the problem. Between the upper and lower carburetor I noticed a split brass clamp on the throttle shaft that was rubbing on the top side. I just can't explain why after all these years it suddenly began to rub. All I did was loosen the socket head screw holding it in place and slid it down the shaft just ever so slightly and re-tightened the screw so the clamp had enough clearance. It was a little tricky getting in there. Fortunately I had a long enough screw driver to reach. Throttles seem to work nice and smooth now.

    • I love my custom Adam Bricker rods.  The guy just makes rods that look, feel, and preform well. Plus he has some really great options like a rod butt that pops out the back with a fish hook remover. You can also get the option of being able to change out blanks if you want. Which comes in handy if a guy goes from panfishing to walleyes. Plus he stands behind his work. The guy is an artist when it comes to building rods not only with looks, but preformance & function. Nothing else comes close to what he builds. With that being said, I do consider them a luxury item.   I have a slight addiction and have about 50 open water rods and 40 ice fishing rods, that range from cheap to expensive.  rl_sd pretty much said it all though. For $30 or less a guy can get a solid ice rod combo that preforms just fine. One of my favorite ice rods is a south bend Rod and reel combo I picked up for $25. It has an 8 ball Bering reel and a ML Rod that works well for perch and walleye.

    • Yep.  Before we were married, camped at fall lake MEA weekend.  In a tent.  Snow falling in the cornflakes.   I was so much older then, I'm younger than that now.  Or something like that.  Mama ain't happy ain't nobody happy.
