I had the same exact problem with mine :) I adjusted the valves and cleaned the fuel bowl on the bottom of the carberator, and it helped for a while, but started again a monh later. Recently, I took the head off and found a large amount of carbon deposit in the head and on the piston. I believe the new 10% ethanol fuels don't burn as cleanly as before. You may try to run a higher octane fuel or a small amount of fuel system cleaner through the engine to try to remove these deposits. Let me know if this helps :)

Starting hard


Hi Ted, most likely the choke is not coming on fully. To fix this adjust the choke cable or if the choke is on the throttle adjust the throttle cable. Regards Phil.

Toro Proline 52" stalls out after warming up


Do you know if that unit has a fuel pump or not? If not, then engine vacuum is what draws the fuel in ... but only IF the hoses involved DON'T have any cracks or splits, and they fit TIGHT on the ports to which they connect! Try using an eye dropper and squirt a little gas in the air intake under the air cleaner. Does it fire then?

Lt1050 black smoke after 15 minutes


The black smoke and black spark plugs indicate that the engine is running very rich (ie too much fuel). This could be caused by the choke not opening fully after the engine starts and the fuel mixture is too rich OR the fuel mixture setting is opened too far.
Check the choke lever, make sure the choke is fully open when the choke is in the running position.
When the engine is running with the throttle is in the 3/4 rev position then adjust the fuel mixture to get the highest RPM.

Engine starts but won't continue to run. Choke doesn't stay closed after starting. will stay running only if I hold choke closed manually.

Your carburetor needs cleaned. It is dirty/has debris in it. If it has a bowl that is. If it has a diaphram (carburetor mounted on the fuel tank), replace the diaphram. They go bad.

I hope this helps get you going.

How do you start it?


what kind of mower is it?
For any mower you need to check that you have proper oil level, and that there is gas in the tank. If it is a riding mower there are a few things to know before you start. There are safety interlocks that have to be complied with before a start is permitted. The blades must not be engaged. Someone must be in the seat, and the brake must be fully engaged. Move the throttle to choke for starting (or pull the cable out if that be the case), start mower. Return choke to normal operating position.
For a push mower check your oil and fuel. Prime the carb. if necessary, push the button by the carb. until you are pushing fuel and then a couple more times. If it has a throttle cable put in choke position. Pull back on the safety bar. Pull cord to start. Throttle cable to normal running position, generally full throttle right before you start to engage the choke.

I hope this helps, if any questions just reply. Be sure you let me know what you did and what kind of machine it is.

If this is really helpful, please rate.

Toro riding lawn mower. 12 h/p is hard to start


Hi there, It is most likely that the choke isn't closing fully. The throttle cable will need to be adjusted to cure this. The cable is clamped where it joins the engine. Simply slacken the bolt and move the outer cable out a bit. When you operate the throttle control you should see the choke start to operate near the start position. Make sure that the choke control rod operates to its fullest extent when the control is fully on the start position.

I have trouble initially starting my MTD Yardbug mower. Once going, the engine runs great, but it seems like when the throttle lever is set to choke, it doesn't actually choke. I usually have to either...


Sounds like your throttle cable is out of adjustment (i.e. when you put the carb in choke position is doesn't actually go into choke).

Craftsman 7.0 HP Briggs & Stratton mower stalling


Check the muffler, if the muffler is clogged it could cause overheating of the engine, and could keep the engine from getting the necessary fuel-gas mixture.

Choke stuck


You may have to replace the choke cable assembly. Sometimes they rust to outer sleeve
