Craftsman DGS 6500 - needs carburetor

[JP98]

Hello-

I recently bought a Craftsman DGS 6500 fairly cheap. It has a 26 hp Kohler motor. It's in good condition but hard to start and runs rough. The previous owner says it needs a carburetor. I've already changed the spark plugs. Not much improvement. I've been searching the internet and found several but not confident it's the right part. Can anyone help me with the right part number for a new carburetor? Thanks!!

That engine uses the 32 853 12-S carb. Not cheap so I would start with a carb rebuild, but also need to check to make sure there aren't other things going on also. Compression, valve clearances, spark. Also I would pull the blower housing and check the part numbers on the ignition modules to make sure they match, and to make sure somebody hasn't tried to convert the DSAM or DSAI to the fixed timing ignition modules instead of the MDI modules.

Thanks for your input I'm ordering a compression tester. I am getting spark. I confirmed that using a spark plug/ coil tester. Previous owner said he had replaced ignition coil packs back in 2023. I'm going to take it apart the next weekend or so and will check the valve clearances. Do you happen to know with that is is?

Ok, so I bought a 32 853 12-S carb from Amazon and installed it this past weekend. Installed a new fuel pump, gas filter, and a fuel shut-off valve. All came with the carb kit. I've never done a carb replacement before so took my time installing it to make sure I didn't miss anything or lose parts. I watched a youtube video beforehand how to do it. I thought it went pretty smooth. To my delight, it started after a couple of cranks. It ran nicely for about 1 minute then died. I tried to re-start it but it just turned and not start. I let it rest for a few minutes then tried it again. It started immediately but died again in like 10 seconds. Did this a couple of more times and it would start then die almost immediately like it's not getting gas to the carb. I disconnected the hose from the fuel pump that connects to the carb and started it to see if fuel is coming out. Gas is flowing. So, the fuel pump is good. What's the next step for me to troubleshoot? Is my new carb possibly defective? I'm a newbie at this. I hope it's something stupid that I just missed.

Is the fuel solenoid on the bottom of the carb clicking or can you feel it click when the key is turns on and off. I am thinking there is an issue with the afterfire solenoid on your new carb.

I don't know but I will test it. If it does not click, I guess it's bad? Is this a common issue? Can I bypass it somehow while I wait for a replacement?
If it is clicking, what else should I look at?

Not a common issue but I have had issues with Amazon Kohler carbs with faulty fuel solenoids. You maybe able to use the solenoid off of your old carb. If it doesn't click need to check to make sure there is battery voltage getting to the solenoid. Have seen a few key switches energize the solenoid in the start position but not in the run position.

Great suggestions. I'll let you know how it goes. Thanks!

Anti-afterfire solenoid on carburetor gumming up and not working is a fairly common problem. People also don’t understand how they work. The four options for a non working solenoid: 1) replace 2) clean and replace 3) bypass 4) replace with exact size bolt and gasket.
