DCH340 FYI - All 3 of my Choke Pulloffs are Bad (& other problems)

If you tear down the carb to the body, I would highly recommend ultrasonic cleaning the body.

I've had the element in the fuel filter come loose. After two cleanings I started looking for the cause. Shake the filter you can hear it rattle inside. Cheap filter quality.

I did check the filter, seems good. float bowl is still clean.

I always get the clear bowl type.  I thought I had gotten Hastings but it looks like a lot of other manu's make them:

NOTE:  I also think it's a good idea to replace all rubber fuel hoses with alcohol resistant ones.  And there is a lot you need to know to actually get the good ones.  (I haven't done this - too lazy/busy - my 620 is still my ONLY daily driver - no 2nd car online yet.)

I replaced all of the engine bay hoses when I got the truck. I live down the street from a a gas station that has non ethanol 90 octane at the pump, so I run that. little expensive, but the truck seems to like it.

I've had the metal filters actually rust from the inside with no visible rust on the outside, and only a year old when this happened. Clear plastic filters are a better choice so you can get a visual of what's gong into the carb.

 

Also not a bad idea to run two filters.
