6.0 hp Tecumseh cuts out/stalls

[sixburgh]

My 6.0 hp tecumseh has been modified.....off road .225 cam, hedder, no gov., valve springs, K&N air intake, 26 - 28 degrees of timing, carb venturi honed out slightly, rpm set at 5800.......problem is: It now cuts out over bumpy terrain and will usually stall when coming back down a hill. It has to be held at WOT while it pops and sputters to regain an idle. A reliable source said to lower the plastic float a little more. Anyone?? Is it a fuel problem or an ignition grounding out problem causing it to load up? Any suggestions?? Thanks.

does it have low oil shut off?

 

[residentg]

sounds lean - did you "increase" the jet sizes? I am not all that familar with that carb, so I do not know the specifics.

 

[sixburgh]

no low oil shut off and I was told that the carb was plenty rich....so no increase in jet sizing. I should check the plug.....it's an E3

 

[freakboy]

mabey test it with a normal plug

E3 look cool but perform like **** on small engines. Also this is a carb issue, techumseh carbs suck *** and when the motor bumps the gas and **** ****s off in the carb bowl and floods the engine or deprives it of gas, whatever its in the mood to do. Only real thing u can do is buy an aftermarket carb or you can try moving the float lower but i really suggest an aftermarket carb

Recommended plug? It came with a champion RN4C. How about some info on a better carb??

 

[solomon]

for the plug use ngk or champion. I usually use a Champion J19LM i believe
As for a carb anything not tecumseh or briggs, maybe a honda carb.

I would never put any money into a tecumseh, but if my life depended on it i would get a mikuni.

 

[sixburgh]

Will a Honda carb fit a tecumseh?

 

[freakboy]

yeah tecumseh's suck so badly. there carburetors die like every day.

 

[sixburgh]

I know you hate tecumseh Kaptain but it's built and runs strong except for the carb issue.

 

[freakboy]

go with a minkuni.

 

[sixburgh]

Really?

yeah tecumseh's suck so badly. there carburetors die like every day.

It now has so much power that my yard is too small......

 

[sixburgh]

Anyone running a mikuni on a tecumseh powersport?

 

[solomon]

i dont think it be smart to use that carb it would burn up your piston

 

[sixburgh]

Hmmm....ok, thanks. I'm going to check out a few things tomorrow.

 

[freakboy]

how would it burn up a piston? ITS A ****ING CARB

 

[solomon]

it allows too much fuel duh. Any motor that gets too much fuel than it can handle will burn too hot on top of the piston and burn it out

 

[EagleTalons]

Too rich will run cooler engine temperatures...
