tecumseh help!

[imSRB]

ello, I have 5hp tecumseh engine and was looking for some help. so heres whats up the engine somkes alot an oil also leaks out around the area at the top close to the nut around the head gasket. I started to take it apart, got down under the ohv cap and the spring pistons and it look good from there, but was to afraid to go any farther cause of springs. what could it be? also the thing would start up and jus take off is that a direct drive or a sticky clutch, but i took off the clucth and it was a little rusted but the springs were still good. help please?!! you can also private message me that whould be fine. thanks

sounds like that teccy has reached its lifespan, the engines are only built to 150 hours runtime. its possible that your valve seals are shot. depends, what color is that smoke?

Sources?

Yup sounds like its about done! lol Thats what mine did when it got tired of pushing me around.

 

[BriggsTwins]

Do you have a compression or leakdown tester?

 

[BriggsTwins]

none handy, thats what i have read, ill look

 

[BriggsTwins]

ok, air cooled aluminum bored engines only have around 150 running hours. Steel rings on aluminum dont do good things

 

[Russ2251]

Is probably closer to 500 hours minimum.

 

[imSRB]

ok, the smoke is white but could it be a blown head gasket?

 

[BriggsTwins]

very possibly, only way to know is to look

 

[freakboy]

White smoke is unburnt fuel... so if the head gasket is blown you wont be getting compression which wouldnt alow the engine to run at all.

 

[Russ2251]

Check it again. Black smoke is unburnt fuel.

 

[freakboy]

then what is white?

 

[newrider3]

Usually water, but seeing as this is an aircooled engine...?

 

[Russ2251]

Oil causes white or blue smoke in air cooled engines.

150 hours is pretty low, EVEN for a Tecumseh. I have a cool bore briggs, from 94 or 95, bore and rings are both fine and it was used for years on a tiller, it most definitely had more than 150 hours.

Imsrb, did you overfill your oil by any chance?

 

[imSRB]

maybe, yeah when I got it i had some motor oil so i pored it in and when i filled it up i had a littile left so i put it in, could that be it?

Check the dipstick, if its very far over the full line, then possibly.
