Tecumseh carb arghhh

[supermanotorious]

so I boiled the carb in lemon juice, cleaned it with carb cleaner, blew it out with air hose (while air blasting something hit my hand so hard it hurt), put it all back together, had fuel spilling out of air intake, looked around, saw rubber o ring on ground, put it back in carb above needle, engine started! ran for about 10 seconds then died, now I cant get it started again, what do you think happened? I still have spark....


UPDATE:

uh oh it seems I DONT have spark, how did his happen after a 10 sec run

 

[supermanotorious]

I'm wrong again, I have spark, took carb apart again, blasted with air to make sure there was nothing in the fuel line that jammed it up, still wont start

 

[CaptCanadia]

Dont you just hate Tecum****? I'm working on one at the moment and it won't run either, but I think that's just cause of spark.

Maybe you left some lemon juice in the carb?

 

[r_chez_08]

Put a teaspoon of gas in the spark plug hole.
If it fires up then it is probably the carb that is playing up.
If it doesn't then it may be a bad plug, coil, compression or timing.

 

[Doc Sprocket]

You may have to run a bit of fine wire into some of the passages in the carb. A good chunk o' crap can go un-budged by air.

To spark, or not to spark? That is the question! Work one issue at a time. Deal with the spark thing first. Is this a solid-state or breaker points engine?

 

[zeeman]

Check to see if you sheared the key. If those Tecumseh's are not torqued down tight, tight, they will shear the key, and it only takes a few seconds of running. Did you have the points out and possibly did not tighten the nut on the crank enough?

 

[supermanotorious]

I never messed with the flywheel, I really dont even know where to find the key

 

[Doc Sprocket]

It indexes the flywheel to the crankshaft.

LMAO...I'll take them over B&S anytime.
Send them all to me. I'll put 'em to good use.

well the shaft is turning still so if the key was sheared would the shaft still turn as I try to pull start?

 

[Russ2251]

Yes, because the stater cup is bolted to shaft.

I send them to the scrapyard. I think like 10 or something so far.

 

[Russ2251]

I send them to the scrapyard.

Too bad. A little Tecumseh "knowledge" and you could have turned a hefty profit.

i agree. i have 5 of them now

 

[HellSpawn]

Send em my way too if you don't want them! All of my best motors have been tecs. Heck, the only problem I've ever had with any of my tecumseh's was with my 8hp that I had on my golfcart. Thing had such wicked compression I had to stack headgaskets to lower it. Was beginning to get hard on my arms/hands pull starting it all the time. And my god was that thing a monster.

X2 I don't like Tecs but Briggs make (and always have) the biggest heaps of crap in the small engines world.

Put a teaspoon of petrol in the cylinder and then get back to us.

It's hard to diagnose why an engine wont start when it's unclear what the problem is.

 

[Doc Sprocket]

LOL. I'm actually thinking about using the carb off my old H60 on a clone project! Features a nice adjustable main needle jet, adjustable idle, and even a pushbutton bowl drain...

I know whats wrong with them, it would cost more to fix them then they are worth. I prefer Briggs, but Tecumseh are ok.

 

[Doc Sprocket]

What's wrong with them that costs? The usual stuff is labour only...

Scored pistons (aluminum bore) , bad rod knocks, worn piston rings. Aluminum bore engines are disposable, once they wear out you cant hone or bore them, and to do the machine work for the rod is not worth it. I strip them bare, save the good usable parts, then scrap the bare pot aluminum for 50 cents a pound. And broken worn tractor transaxles have lots of aluminium. I got a recite for $139.40 from the scrapyard. $47 in aluminium.
