Why won't my Bruin idle for more than 20 -30 seconds?

Starts and runs fine and runs well. Just won't stay idling, looks to be blackening the spark plug a bit. No adjustments of any kind made

Running too rich. Choke on? Clogged air filter? Dirty carb?

Wont idle without choke being used


Main jet dirty. Likely Ethanol fuel fouling. Remove and clean jet. Check all rubber tubing to/from carb for cracks/deterioration and replace.

Troy Bilt self propelled lawmower won't stay on. It's been fine this year, today all I did was add gas and added the mulch shoot. I turned it on, it was fine. Started mowing, got halfway across...


The trouble you are experiencing could result from several different things. First, check the oil when the engine is cold and completely settled in the sump. You do not want to overfill the engine with oil. If the oil is on the full line (not above it),then the low oil sensor is not shutting off your engine. The oil level should be exactly on the full line-not above or below. Second, remove the spark plug and clean it with a small wire brush or sandpaper. If you are unsure about how to clean the spark plug, replace it with a new one. If both of these procedures have been performed and the mower still doesn't run correctly, the problem is almost certainly with the fuel supply, fuel quality and/or carburetor.

I've got a 1985 honda vf500c. It runs perfect when it is moving, but when I come to a stop and pull in the clutch, the engine takes a few seconds before returning to idle speeds and will stall if I don't...


More than likely, the idle (pilot) jet is partially clogged. This is common when it will idle fine with the choke on, but won't idle without it. Sometimes a fuel treatment will clean the carburator, but not usually successful in cleaning the idle jet. Usually it requires removing the carburator bowl and and cleaning with the use of a gauge wire. The idle jet is usually recessed (next to the main jet).

A good video to show a generic carburator rebuild can be found at this link: http://www.youtube.com/watch?v=exa467_eoXw The guy goes through a pretty detailed description while going throught the process. The carburator will not look exactly like yours, but it will be similar internally.

I have a JD 2010, seem to be running fine , left it idleing out in the yard, while in the house about 30 min , went back out to find that it had quit, now it will not fire, where to start? thanks John


If left idling for too long the plug will blacken up
Remove & clean lay on head to check for spark if none then replace
Check air filter is clean & check operation of cold start mechanism
