It starts fine and runs on choke but not off choke

It cranks immediately; new gas, full oil. warms up nicely on choke, but the minute we take it off choke, it starts to sputter and dies. Every time.

It sounds like you are not getting enough gas. I think it's the diaphragm, When you take it off of the choke diaphragm controls the gas flow, apparently yours is just shutting down. It's very inexpensive, and very easy to replace. Good Luck :)

Trying to start for the first time it cranks but will not fire up. I have fresh oil fresh gas and have gas valve open. I tied opening the choke and closing and no success. Am I missing something?


Remove the spark plug and see if it is wet. If it is, you have gas in the combustion chamber. Check the gap.

Does it have a kill switch? Is it electric start?

The choke needs to be in operation until the generator is warm.

Yamaha 5200d it starts and runs 2/3 minutes and shuts down oil is full low oil lite does not light up carb is clean


This generator is equipped with an auto choke. What is likely occurring is as the engine warms up the choke is returning to the normal choke off run position leaning the mixture two lean to maintain operation of the motor.

This is occurring because the residual fuel that was left in the carburetor has evaporated and the gum residue is reducing the fuel flow through the carburetor. When the choke is applied the mixture is rich enough to support running and as the choke returns on its own to the run position the mixture leans out and the generator stalls..

Override the choke when the engine is starting to falter to confirm the problem. Continuing to attempt to run the engine possibly adding a carburetor cleaner additive to the gas will likely return the unit to normal operation.

If attempting to enrich the mixture by applying choke when the engine begins to falter does not work then a fuel flow problem to the carburetor may be the root cause. I would look for a plugged fuel filter or restricted fuel flow from the tank to the carburetor. What is happening is when the unit is at rest the carburetor is filling with gas and as it is running because of a restricted fuel flow the level lowers in the carburetor bowl resulting in a mixture to lean to run.

Hi, if it re starts immediately and requires choking it is a fuel related problem. If it has to sit for a while before restarting, check for lost spark as soon as it stops. If no spark make sure the unit is level and oil is full when sitting level otherwise the oil cutoff switch will shut it down. If oil and unit levelling are ok and there is no spark the cdi unit is most likely faulty. Hope this helps, regards Phil.

It will start on full choke and run for about 5 seconds and shuts off. I changed oil because it was black. It did same thing a year ago and shop said the fuel line was blocked? I ran it for about 25...


first if its a honda,is it a gas/oil mix as the gas/oil mix plugs up quicker than a 4 cycle engine ?even 4 cycle engines that get bad gas i.e. water in the gas will plug up the carburator from rust, white rust(from water minerals) corrosion,dirt,etc.,when its running and just as it dies out,pull out the choke and see if it picks back up in r.p.m.'s,if it does,then you know its lacking fuel from starvation from plugged fuel lines/carb to keep running,then you need to re-build the carburator or you could first try a can of carb cleaner while its running down into the carburators intake,but this is a tell-tale sign of a bad/dirty carb,try this,with a small wrench,pull off the carburarors "sediment bowl" located just ubder the carbs body and carefully unscrew the brass nut and remove this bowl(careful to NOT lose the gasket) and see how moch water/dirt,etc., is in the bowl if theres water it will look like droplets in the gas in there,if you have this contamination you need to clean out both the gas tank and carburator and all fuel lines leading to and from these to the engine

What's the best choke setting for starting a cold generator


Full choke to start, open choke partially immediately the engine starts to where the motor runs smoothly, continue opening as soon as you can while keeping the engine running smoothly. Be sure to open fully before leaving the unit, running it with the choke partially on can cause a rich fuel condition which tends to wash the oil off the cylinder walls and it also dilutes the oil with gasoline.

I have a coleman powermate premium plus 6250 generator,put in new plug ,new filter ,changed oil,cleaned the carb,put in new gas. runs ok at half choke but when go full choke it starts backfiring and runs...


if you are running the engine at full CHOKE, then it is flooding the engine, but if you meant off full choke, then the carb is still stopped up. Try soaking in carb cleaner overnight after removing jet & all rubber goods. HOPE THIS HELPS.

Honda em2500 starts, runs 1 minute, quits and will not restart


If the oil level is low it will do this, but I also know this to happen when the oil is very cold (thick) an won't fow back own o the crankcase where the oil sensor is. The slow return results in a low oil level. My solution is to start it, when it dies wait a couple of minutes and retry... after a few starts, the oil will warm up, thus flowing back down faster and it then will run. Another option is to use a thinner oil ie;5-30w.
