i have a 5hp texumseh and when i start it up it idles up and down and when i turn or take out trhe bolt for the gas flow it ends up doing nothing. i'm looking to learn how to fix that and i also rebuilt it the top and lower end of the carb. i would be thankful for some help.

That may be a governor issue. If possible, post a video of what it's doing.

If you're referring to the mixture screw, it won't do anything at idle, you need to open the throttle to make a difference; the idle circuit in a carb is separate to the power circuit, changing the mixture at idle will have no effect on the idle speed.

My best advice to you is do some research on basic internal combustion engine principles; once you get that, you'll have a better idea of what does what & how to diagnose & repair a particular problem

Try these out and see if it helps.

Sounds like a carb issue to me, probably needs a good cleaning.

Ditto to what TS posted. But some of those Tec carbs can be a bear to get clean, especially if you do not remove the welch plugs.

I just threw in the towel on one. After viewing the video, I realized that there were a few things I had missed. I think I am going to get a kit and try again. I don't like to get beaten by anything and if successful will give me a good carb for a little $.

 

[Monkeys1990]

i rebuilt the whole carb and clean it but i think i might be getting more trash in it so im going to clean it again and post a video showing what it does after i do that. thanks for your guys help.

Is there a fuel filter present or able to put one on.

 

[Doc Sprocket]

I'm with him^. Don't even try to run it again if you suspect it's inhaling more crap. Filters are cheap and easy to get. Get one. $2. That's it. Stop by NAPA.

 

[Monkeys1990]

not enough space to add one.

Run a longer fuel line to make space

I have the same motor.Adding fuel line might be possible but not the easiest thing to do. The fuel line runs behind the flywheel and only sticks out of the cowling about an inch or so. Much easier to remove the tank and flush everything. With a good cap and air filter and clean gas there shouldn't be any trash.

Just an option if you want more power, I have a Tecumseh Powersport 6.5HP in very good condition for $120 delivered to your door. I pulled it off a low hour Murray Kilowatt kart that I just upgraded to 9HP. I pulled the carb, fully disassembled it, gave it a deep clean in the carb dip tank, then reassembled it and drove the kart before removing it.

 

[Doc Sprocket]

Make room. Always run a fuel filter. You'd be amazed how much crap there is in jerry cans and everywhere else. I have re-routed fuel lines on Tec's to make this happen. I came to a conclusion years ago- I hate cleaning carbs, better to just install a $2 filter and be done with.

No where in this post have I read anything about replacing the fuel hose or cleaning the gas tank. Also if this is a standard tec fuel tank, put a shut off valve with a strainer in the bottom of the tank, these valves look like a tee fitting and screw into the bottom of the tank.

Well, there was this-

remove the tank and flush everything.

I read that, I am referring to that in none of Monkey1990 posts did I read where he replaced the fuel line or cleaned the gas tank. You can clean the carb. multiple times, but the source of contamination has to be either from the fuel line or crud/debris in the gas tank. Of course there could be water in the fuel.

ok i did leave out that i did replace the fuel line because it had crack and i havent fluch the tank but i have check for trash but i will be cleaning it out and the carb abd trying to put a fuel fliter on it.

Point taken. I misunderstood you.

You can't really "check" for trash inside a tank. Particles smaller than you're going to notice, can jam up the carb faster than you can run off and buy a fuel filter... *hint*
