SOURCE: 2003 john deere x465, runs

carb is a good place to start but if pops thru intake you need to do a compression check if you have the means this is the easiest find out or at least make sure it does not have bent or burnt valves but the most common problem for the one you described is the carb.

Have a John Deere 11hp. Runs great for 5 minutes, mows fine too. Then is starts to miss and pop and will barely stay running with choke. Then it pops some more and acts like the safety was bumped and dies...

Hi Laurin:
Considering all that you have done, it is possible that you do have a bad condensor. If the consendor has a defective component that reacts to temperature, it may be that when cold, the correct function is happening, and as it warms up (the 5 minutes run time)
the expansion associated with the temperature change causes the malfunction.
Considering the relatively low cost, I'd be considering doing both the points and condensor.

Have you checked that your float is working properly in the carb? If it is sticking with the plunger shut it will block fuel inlet regardless of having fuel supply?

Have you checked to see if there is definitely fuel in the line at the carb when it's acting up?

Have you made sure that there is still spark when it quits running? You could have something that is grounding out when it warms up and makes it quit firing that while you 'fuss' with gas issues, cools enough to spark then fails again. Hard to say without more details. Also are you sure there isn't a clogged fuel filter in the tank, carb-inlet or inline somewhere?

1980 dodge d50 running bad

My first guess would be a weak coil or something going on with the carb.
It could have jumped time but you would probably hear noise coming from the timing chain.
Can you tell if it is not firing on one cylinder ? Checked compression ?
Too rich or too lean on the fuel mixture ?

John deere lt155 lawn tractor shuts off when it gets hot while mowing, could this be electrical?

I had a similar problem lasy year.
Try this:
As soon as the machine seems to be stalling, loosen the gas cap.
If the engine continues to run, clean the gas cap vent hole(s).

well to see if changing the timing helps / loosen the distributor bolt so you can turn the dist , keep track of where it is before you turn it incase it is right . with it running by turning the distributor it will either get better or worse / make sure you have good spark plugs and wires ,make sure there on the right plugs and cap . find the firing order / do a test on them all with them out of the engine but grounded and observe for a bluish strong spark on the plug if it's weak and red color spark you might need to check your ignition points or coil /cap / rotor,even do a compression test, if you have the timing right then obviously a bad carb is next to check
