I've got a 2hp Strikemaster Lazer Mag Express. TC300 3219J is the model #. I'm trying to figure out if I'm missing a spring or something. It starts, runs, and everything is great except it doesn't always return to idle well and the auger continues to slowly spin sometimes. I'm wondering if I'm missing a spring or something else that isn't pulling my throttle back to idle the way it should. I attached a couple pictures, one with an arrow where I think a spring would connect to the throttle shaft/shutter. Could someone take a look at theirs for me and let me know if you have any ideas for me?
Thanks!

No spring goes there
-
Thanks, any other ideas why it doesn't go all the way back to idle? I sometimes have to move that throttle lever by hand to close the carburetor shutter, to get it down to idle. Is there another spring somewhere else that might be weak?
-
it sounds like the linkage is sticking or binding somewhere, try taking the linkage off of the carb and moving it by hand to see if it binds anywhere, also do the same thing with the carb its self.
-
Still got the small return spring on top of the carb?
-
I would bet the wind vane / air vane is broken.
-
If vane is broken then engine will be turning very high rpm's at full throttle.
-
I thought that as well. on my old Strikemaster lazer it would run at High speed and then some times it would turn the auger slow my vane was broken just right that it would do strange things needless to say I replaced the vane and the problem went away.
-
Thanks guys. I took the carburetor off and I cleaned it out yesterday. But this is not a new issue from that. It's been like this for a while. Anyways, the air vane is fine.
Here's a couple more pictures to see if they help at all:

This is what my carburetor looks like. shanedoe, the spring (#2) was bent up a year ago when I had it apart. Is this the spring you're referring to? Or the spring connected to the air vane in the bottom picture? I'll probably order a new "Throttle return Spring", part #2 in the below parts diagram since I know that got messed up last year. I just can't see how that spring does very much, but maybe it does. If you know more about it, could you explain what that spring does?

And here is where the governor spring connects to the air vane. The air vane seems fine, but I suppose its possible it could be bent or something. Is that one of the main pieces that is supposed to assist in closing the throttle lever/shutter?
This connector spring seems to be fine also, and seems to only affect pulling the throttle shaft/shutter open to increase power. Doesn't seem to have anything to do with letting off throttle back to idle.
-
Duncan77, was your air vane broken, or just bent? Maybe mine is bent or something where it doesn't catch the air as well from the flywheel to return the throttle shaft/shutter closed?
-
I had Jason at strikemaster fix it for me. strikemaster was just 8 miles away from my house until they were taken over by rapala now they are 25 miles away. Call 1-877-572-7278 ask for jason I think he will help you out.

Camo, that little spring acts like a push/pull on the carb(opens and closes). It also allows the carb to close when auger rpm's get too high(the governing). If this spring was damaged at one time it might need replaced.
-
Which spring are you talking about? #2 on the carb, or the one attached to the air vane?
-
The one on the air vane
-
Here is a little experiment. Without engine running open throttle all way. Then let it off. That little spring connected to the vane should have enough pressure to close throttle back up. If not maybe bad spring or something is gumming it up. It is very sensitive.
-
Have you had this auger for a while or did you just get it? If you had it for a few seasons how did it run last year? One thing that could be causing your problem is the idle speed could be set too high. The one think you have going for you is your motor is a Teucumsen (not sure I spelled it right) motor and any small engine shop could work on it since it was an extremely popular motor when it was made.
-
shanedoe, that spring attached to my air vane isn't long enough to return the throttle shaft/shutter closed. Maybe the spring has shortened up? But that doesn't make much sense. Should I try to stretch it a little so it's longer to return the air vane back to idle position?
I just ordered a few parts since they were only a few bucks per part, so I'll try a few of them when they come in.
Ordered a new governor spring (the one attached to the air vane), a throttle return spring (#2 on the carburetor), and a new air vane.

Here's a link to the shop repair manual.

Camo, also make sure the aluminum slide thing that the vane spring is connected to is sliding back and fourth freely. Little wd40 always helps. Everything must move smooth. Replacing the two springs is a step in the right direction. A process of eliminating things that could be the problem.
-
Thanks for the repair manual Chris. I had a copy, but the pictures in my copy were pretty poor quality for some reason. If when I replace some of the parts it still isn't going how I want, I'll take a video of some of the parts and what its doing to see if anyone has any other ideas. There's not too much else involved with this though, so I think I'm heading in the right direction eliminating possibilities as shanedoe said. Thanks for all the ideas and assistance so far fellas! It's usable as it is, just think it needs some small fixes and adjustments to make it right.

Good news! It's working like new again! The main problem must have been the governor spring. Mine might have been stretched or something, but getting the correct spring and new air vane, and placing the spring in the correct hole on the air vane seemed to solve the idling problems. But while I was at it, I replaced the throttle return spring. I also replaced the fuel line, but that was a different issue, since the old one was beginning to show it's age.
Glad I got it nice and tuned up now though, and ready to hit the ice!
Thanks for the ideas and help with possible solutions! ;D

I'm glad you got it working and to help. Good luck with it.

Dude, that repair manual is great! Wish I had that sooner but am still happy to get it.
I just took mine apart and found a piece of the old weave type diaphragm stuck in the main jet. No idea how it got in there but sure explains why it wouldn't run right!
-
Hey would anybody be able to share the shop manual for this auger? I am having similar problems. Is the return spring on the bottom of the carb supposed to do something mine just stays put.
Thanks

trying to get to three posts!

A quick point on an old thread but I hope it may be useful to someone. Make sure the governor spring is installed correctly. I picked up a used StrikeMaster that wouldn't accelerate, stay at WOT and/or surged like crazy. Put in a new vane and spring, rebuilt carb, changed out carb all without a lot of success. Finally noticed that the vane spring was installed upside down (I had diligently followed suit with all my disassembly/re-assemblies). When the spring is installed upside down it binds and/or will not go to WOT. Flipped it around and problem solved.
