Question about Coleman Powermate Powermate 5000W Generator

Open Question

I have a 5000 Watt Coleman Powermate Generator PM05455007 with a 10 HP Briggs. I need to get a drawing of the carburator so I can re-assemble it correctly. I've looked all over coleman & briggs websites but can not find the information I seek. The engine has the following information on it: Family: 3BSXS.3422HT 275386 A decal is on the air cleaner cover that reads: GenPower 305 Any ideas where I can find a drawing of the carburator? Also, what is your experience in converting this to a propane carburator. Is it a good idea or am I inviting a different set of problems?

SOURCE: Coleman Powermate 5000 no electricity, runs fine

Take a look at your outlets. Some of these units use pretty cheap outlets and short out. You will know if it is bad when you look at it. Hope this helps.

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

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.

SOURCE: My coleman powermate generator will start but will not generate.

The voltage regulator controls the output. You will need to check that first.

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

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.

I cannot locate the owners manual for my Coleman PowerMate 6250 generator 10 hp? Any place I can find this online quickly thank you

Most PowerMate manuals are available here: . However, describing it as the PowerMate 6250 10 HP generator is insufficient to find the correct manual. The Coleman PowerMate line has several models with 10 HP engines and a 6250 Starting Watt (5000 W running) capacity.

These include the Powermate PM0435005; the direct link for this manual is .

Please add a comment with the actual model number of your generator if you need further assistance with finding the correct manual for your generator.

I hope this helps.

I have a problem with the carburator at my coleman powermate pro gen 5000, where i buy this carburator on line. thanks

To find the correct part on line, first determine the engine model number and code stamped or labeled on the engine fan cover. For example will be Briggs, or Honda etc. Once you determine the Engine brand and model number, you can go to a web address like Jacks small engine, or even ebay or a replacement part or carb kit. May be easier to take the engine information to a mower repair shop in your area for a replacement. The engine on your generator is similar to one used on lawn equipment. Good luck

This is really not something you can do. There is a fair bit of engineering that would have to be done and then there is wiring and mounting, etc.
