Generator with Briggs & Stratton,no gas is getting in carburetor

I have a Coleman 6250 Generator with a Briggs and Stratton engine
3BSXS-3422HT series 275385
I cleaned/soaked the Carburetor with seafoam, then blew out all the ports with an air compressor, new oil, new gas, starts on starting fluid but won't run, gas is still not getting into the carburetor?

    I put the air filter back on and low and behold it started!! for 2 minutes, I shut it off to take it down off of the porch and started it again, to much gas was coming out, took carb off, dried out the filter. And here we go again no gas in the carburator.

The needle valve may be stuck which would not let gas into the carb. I don;t think rebuild kits are too expensive. Pull the carb and take it to a lawnmower repair shop and they should have the parts. Before that though pull the bowl and make sure it has gas in it. If no then remove the fuel line and make sure gas flows from it. If no then could be the fuel shutoff valve is not operating properly or junk in the gas tank is obstructing the line.

I've had many small engines that did similar. Carb problem. Clean it, same problem. I usually end up buying an oem carb on ebay when it comes up cheap. Read up on do's and dont's of small engines and gasoline. If you have a carb problem, if your going to rebuild it, everything must be new. do the whole thing. If it doesnt work, buy a new one. same price as a good repair shop to do it and you get new. don't put crappy ethanol gas in any small motor and let it sit. the ethanol causes varnish, eats at the plastic in the hose, and plastics in the tank... if you change the carb, or get the mower going again....You must take the tank off, wash out with soap and water, (clean the shutoff valve or filter screens if any in there) blow out with airgun. take the gas hose to carb off and throw it in the garbage.. go to auto store and buy 1 foot of hose.. very cheap. now put it back together and you have a nice system ! Ask boaters where the non ethanol gas stations are. they'll usually have a pump off to the side. With any gas, say your storing any motor with gas in the tank, put sta-bil regular one in. not much. since one medium size bottle with the auto measure 1 oz. thing on top can treat a whole cars gas tank... (or 1oz /per 5 gallons for cleaning). after putting it in, run the motor a little to get that stabil gas in there, then store it for a year with no problem. any gas in a can, I would dump out, wash with soap and water, blow out, and use non ethanol gas, treat if its sitting in there for a few months or more without being refreshed. Also there is "Old Gas." cheap gas stations buy older gas off the market by auction. A quality engine doesnt need this either. good fresh gas, treated if stagnant. Shell, Texaco etc are good. -----common problem i see is running sputtering, i usually just pull the bowl off the bottom of carb, unscrew main jet, and i'll be amazed if theres not some small piece of dirt in there. look through it with a light behind it.. you'll see the dirt if its in there.

Looking for a special B/S carburator the run on natural gas, and not regular gas.

there are natural or lpg operated engines in gen sets being sold currently on the market
try talking to a gen set repair /retailer shop to get the make of carby being used on those motors
regardless of the engine make , what is required is the engine capacity (CC) so that the correct flow rate for the engine through the carby can be sorted to get the correct carby
once the carby is identified , it may be possible to get it from e-bay or a gen set manufacture spares that makes lpg or natural gas gensets

How to test portable generator stator for short in windings

You will need what the factory resistances valuea re supposed to be, cold. Then use a high quality ohm meter with 3 decimal places, disconenct all wires off the stator. Check each wire with a meter to the ground frame, if there is any value, stator is shorted. Then check between stator wires ie L1 L2 and compare resistance value with factory values.

First check your oil level. The low oil sensor kills the ignition to protect the engine from damage.

Second, replace the spark plug.

Looking for a carb for a Coleman Powermate 500/6250 generator with a 10hp Briggs and Sratton engine...any suggestions?

As it is a Briggs Engine most quality Briggs dealers can get the carb. It isn't special to Coleman I don't believe.

My powermate 6250 only runs with the choke fully open. Purchased used any help anyone?

Damned FixYa ate most of a detailed post.

If Briggs & Stratton, it will likely have two adjustment screws on the carburetor. One is for low speed, the other for full load.

Take note of how far you turn them so can return them if needed.

From your description, using the choke normally means the engine is starved for fuel so backing off the mix screw might cure it.

If not, then likely one of the jets is fouled so you will have to remove the screw(s), counting the turns as you do.

Clean the seats with carburetor cleaner (auto parts store or Walmart) and replace the screws.

They may still need adjustment after reinstalling.

Coleman generator OHV3000

The carburetor is probably clogged up. Mix a bottle of carburetor cleaner with the gas to see if that would help. Also check/replace the fuel filter.
