Some pics of a Coleman 502 Sportster that I recently fettled.
Hey what did you need to fettle to get it working ???
I wish I had a before picture...
I had to:
1. Clean the generator out. It was completely clogged and gummed up with black tar.
2. The knob and valve were stuck. Fixed that with a soak in some solvent.
3. Burner and manifold were a mess. Gummed up and had rust all over. Wire wool on each burner ring piece.
4. Fuel pick-up tube needle was stuck. Cleaned it up.
5. Cleaned out the tank.
6. High heat painted the burner, valve body bracket, and manifold.
7. Citric acid on the brass pieces including the generator, which went from black to shiny brass.
I have the same stove as yours. Bus the flame looks less powefull. I tried to clean the generator with citric acid but the spring inside the generator still doesn`t come out of the tube for better cleaning. Is the spring fixed in the tube? How can I clean the generator? New generators are very expensive here in germoney.
To remove the spring from inside Coleman generators, you need the special tool.
Take a heavy duty paper clip, straighten it out, then put a 90 degree twist on the end, about 3 mm long.
Screw the 'special tool' into the genny and then pull hard..
It should pop out!
That's my company proprietary secret tool! It's obvious I have a corporate spy living with me!
Carburetor cleaner will also help loosen things up too. I let my generator soak in a solution of kero, white gas and carb cleaner for an hour and it was loose enough to pull out with my 'proprietary tool'.
Yeah, I found an old Coleman brochure on the site that showed Original tools for generator dissasembly. The paper clip tool is a cheaper fix !
And they work well!!!
