Need help

[Daniel Sheffield]

I have a problem. I have a tecumseh 5 hp engine that runs but when it gets hot it loses power, then eventually dies. What could be the causes. Have pics on my page. Won't let me attach here with my phone.

Do you do open throttle alot? but it could just be over heating

 

[Daniel Sheffield]

First run so not sure. Yes wide open alittle due to it being a street kart. What could I due to stop overheating.

More air flow...

Do you have all shrouding on the motor, fan cover ect...

 

[Daniel Sheffield]

Yes and unobstructed. Would a oil change help. From what I understand is that it sat for a while. Oil is full though.

That's what I'm thinking; when metals heat up, they expand, making tolerances (the gap between moving parts) smaller; when those tolerances reach zero, that's when engines seize...

...& you didn't change the oil? For all you know, that oil could've been in there since the engine was new...

Oil is full though.

How full is "full"? It's possible it's overfull

 

[Daniel Sheffield]

No it's within the crosshatch marks. Finally got it working after complete carb cleaner. Oil is next though. Just wanted a test. Drove for about 10 min before problem.

And is it ungoverned? Because if you dont it could means you have no suction for oil (cutting itself off)

 

[OzFab]

Umm, what? What does "suction" have to do with a splash oil system?

 

[Daniel Sheffield]

It is governed. But not sure if it is adjusted right. How do I adjusted a governor.

Governor rod is also loose and leaking a very small amount of oil. Normal?

Surprised no one has mentioned this: although I've never happened across it, it makes sense that your valve lash is too tight. When it gets warm the valves don't fully close causing it to lose compression and power.

How would I check this. I don't have any gauges but a micrometer. Also plan to start a thread on the brakes.

 

[mckutzy]

You will need a feeler gauge set... I think even homedepot have them.

 

[Poboy kartman]

Buy a blade type feeler guage for a few dollars...then Google up..(or search here)....for valve lash adjustment .....not really hard to do
...but also not hard to get wrong.

IMO, it's a Tecumseh. That's the problem.

They're high maintenance engines, the parts are rarely interchangeable, they're not very forgiving, etc. I especially hate the carbs and throttle hookups on them.

Don't get me wrong, they're not "Bad" engines, they're just not as user friendly as Briggs. Or even Predator, for that matter.

I'm curious, how old is this engine? It may not even have OHV.

 

[Daniel Sheffield]

Not sure but has the cover on top.

Does it look like this?

If you want to go low budget for cooling, you can get this vent(down below) which will act as a radiator which you can put on the sides or top. This does work knowing since i have done this before

Ok....I kinda hate to go here....(since administration doesn't like me picking on newbies) .... but seriously, dude, you just keep spouting off bad worthless advice time after time.....Maybe you should learn a little first, before you spastically hit keys.

Yes exactly
