Question about Coleman Powermate Premium Plus 6250W Portable Generator

1 Answer

Engine dies I have a coleman powermate 5000 kept in a shed, started 1/ mo except last 2 months.  I started it today and it started OK but when I take it off of choke it sputters and dies, I ran it for about 3-4 min on choke to be sure it was good and warm and still exactly the same.  sprayed carb with cleaner and no change at all.  There appears to be plenty of gas, the filter is clean and opening the filter box has no effect. gas is a few months old but it does run on choke.

Your carburator is gummed up !
Take the float bowl on the bottom of the carb and spray the main fuel jet out with cleaner, do this to the idle needle valve also. If that don't work pull the carb & take apart & soak overnight in parts cleaner & blow out all ports & orfices with compressed air.
Next time you store your generator with gas in it , use a fuel stabilizer !
Good luck !

if it doesnt turn over how did you test the spark?

if i have read it wrong then always try a new spark plug, these can fail under compression but will spark happily outside the cylinder.
if it wont turn over then it could be siezed or dropped a valve.

What brand of engine & horsepower is it?Also about how long was it stored or last time it was run? The reason I ask is if it was stored with gas in it & a fuel stabilizer wasn't added to it,your primary jet is plugged in the carburetor(reason it will only run while choked).

Check the vent in the fuel cap to make sure its free to breath. It could be creating a vaccume in there and starveing for fuel. Maybe run it with the gas cap off and see if the problem gos away.

Try removing the float bowl from the carbuerator and empty it out. Also check the float valve to see if there is debris under it. Thi problem is definitely fuel.
