    No took them off one at a time when I replaced them. Almost feel like the new carb I got might be bad

    what's left??? nothing! short burst of life from the engine from what you pump in and then it dies. I tend to agree.. possibly a bad carb.

My cub cadet 1046 riding lawnmower won't stay running. I've replaced the fuel filter, both spark plugs, and sprayed carburetor ports with carburetor cleaner and it starts but won't stay running.

When you say "stay running", how long does it actually run for? Will it ALWAYS start and run, even if it dies, or will it sometimes not run at all and only turn over?

Ive done a tuneup and replaced almost everything but i won't stay running if i take it off choke it sounds like its boggs down when i do

Depending on the model of the mower; you could be having fuel delivery issues. To run with the choke open points me to the carburetor. You can try to run a tank of "start" through the engine. If it is possible to flush out the carburetor this additive will do it. If not, you may need a new carburetor.

Chainsaw wont stay running Runs 30sec to about 1 1/2 min seems to be starved for fuel

Initial carb setting is 1 full turn out on both low and high side and retry. If no difference, then turn the low side out and additional 1/4 to 1/2 turn CCW. If that makes no difference, then it's time for a carburetor rebuild.

Why 2008 vstar 1300 only stays running when given gas?

The pilot jets are clogged. the carburetors will need cleaned, and the pilot jets may need replaced. Alternatively, Seafoam in the intake and the fuel tank may allow for some improvement of the problem, but a carb rebuild is highly preferable.

Won stay running

Check carburetor & air filter. Clean off all dirt and clean air filter. check age of gas. Cannot be more than 30 days old. Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio (1 gal.) Gas to 3.2 oz. Oil). Do not use old or stale oil/gas mixture. Before putting in fresh fuel, press the primer several times. A small amount of gas might show up in the fuel tank. Remove fuel. With carburetor cleaner, spray carburetor. Put in small amount of fresh fuel. Just enough to cover the fuel filter. Then press primer with fuel cap off, and watch to see if fuel is flowing smoothly. If not or if plastic primer bubble does not come back to original shape after pressing, then you have to take carburetor apart and clean or get new carburetor.

Replaced all fuel lines and pickup fuel filter. but won't stay running without choke.

Take the carburetor off and clean it and check and replace any air filters you may have. Can't say that this will fix it ,but it is a starting point for you. Hope it works and good luck.

Ryobi gas leaf blower starts but will not stay running

I have an Echo weed-eater. It recently developed a miss and will not stay running at idle. If I keep it accelerated it will stay running; when I let it idle it will die. I have replaced spark plug, gas...

This could be caused by several things such as low compression, bad carburetor, scored cylinder or piston, stuck piston rings, air leak, bad crankcase seals, etc. If a carburetor adjustment does not help and if the carburetor is more than 2 years old, I would put a kit in the carburetor.
