Motor Help
 

Tore into a 15 year old tiller that hasn't ran in 10 years this morning..
Im decent when it comes to working on motors at times, but here's my dilema..


Pulled the carbs, cleaned, pulled air filter cleaned, knocked every dirt dobber nest known to man kind off.


Can get it to fire but won't stay running, don't think im getting suction, when I go to prime it, it doesn't seem to get "Primed"

Hope my question makes sense?

Like I said,not the best mechanic but can do the basics.

How did you clean the carbs???

Carb Cleaner

sounds like it needs new fuel hose, open tank cap vent, fresh gas, maybe spray some starter fluid in the carbs?

I'll check the hoses, drained old fuel, added newly mixed. Bout to soak the carbs

what model engine?

Tecumseh tc II

oh, nevermind what i said earlier thought u meant tiller outboard :*****:

x2

lmao.. I was like why would he be thinkin tank cap open? How does he want me to start this with it open lol

throw that piece IN THE RIVER! LOL

Lol. Its keeping me busy today.. felt like working on something and this is makin me mad lol.

Its the carbs. Can spray a little gas directly in and runs like a champ.

Bout to pull this little devil off and soak it

Edit**** When I go to prime it, It's straight air. So a leak??

Brayden, make sure the primer bulb dont have a hole in it. I had a weedeater that had a pin hole in it, and that was stopping it from getting primed

This is making me mad lol.. It's sucking air, so theres bound to be a leak

You should be able to get the fuel line and primer ball you need from a shop that deals with small engins. With the lines being that old they are rotted out.

Just pulled the lines and ran pressured air thru them.. No clog.

Clean the diaphram (sp) on the carb, sprayed power tune through out the carb (best stuff on the market can sit and watch the junk bubble out..

still no complete run. Can get it to fire by spraying into carb, but thats all..


Friggin smallest engine and I can't diagnose whats wrong

fuel line problem....got a leak somewhere.

Still got crap in the carb....if it's been sittin up it's varnished over.....doesn't take but a tee tiny piece to screw up those small jets in the carb...pull jets & blow high pressure air & clean with a tip cleaner for a torch or a piece of wire from a wire brush, also check the primer bulb if it has one, they get hard & crack after sittin up....may have to soak a couple times also.....try Chemtool B-12 that's some goooood stuff.

make sure your float is opening and closing correctly, if float stays open it will not prime and it will flood your motor. and Don't use cheap attwood fitings they're made cheap, I replaced mine with moeller from west marine and no more problems with cracked fittings that don't fit right.

It could be a crack in the fuel bulb/line......

But my bet is a clogged jet in the Carb. What I do.....is squirt [using a spray can] some carb cleaner through each hole in the carb until I see the cleaner coming out somewhere. Some of the holes maybe hard to get to, but usually can be done. Also you can try sticking a small wire into each hole and see if it will come out the other side.

Be careful not to get your face sprayed..... wear goggles.

If you are soaking the carb..... put it in a plastic jar and shake it up seveal times and let is sit over night.

Not sure what you mean..... when you push in the little bulb, it only pumps air???????? If so.... you got an crack somewhere in a fuel line or the primer bulb. With that old of an engine..... fuel lines are probably brittle and need replacing. Cheapest place to buy the tubing is Western Auto store...... just north of the Walgreens on Hwy 171.

If the new fuel line are hard to slide on the "connector"....heat the end of the rubber with a hair drier to soften it up some, and then it will slide on.

ya got dirt in the idle jets it wont idle when the butterfly is closed there are two to three little hole that let fuel pass so it will idle sounds like there clogged up..find them holes they will be on the top part of the venturi on the engine side of the carb.
