For our chemists ......
A few months ago I had to clean our Coleman 412 paraffin lantern. The generator was clogged after years of use.
I "YouTubed" and eventually settled on the "heat and quench and tap" method which worked. I removed the coil and thin wire before doing that.
Yesterday with Eskom going down, I fired up the Coleman 422 unleaded petrol stove for coffee. It started off ok, nice blue flame. Towards the end it looked like a Kalahari sunset, it was so yellow.
Yip......another choked up generator.
I decided to strip it. Also removed the heat shield ( lower plate) Use Gungum to reseal it as the original stuff was so vrot I could blow it out. Trimmed off the excess.
Cleaned everything else with a Dremel wire brush.
This is a "Before" pic.
I got some injector cleaner and dribbled it in with a syringe at the jet end and slowly worked the wire. It took ages before the level showed any signs of dropping...very very slowly.
I stuck at it....... mainly because during my Googling I discovered the price for these are now R2600,00 !!! We paid about R350 at Camp and Climb decades ago.
Below is the jet end of the generator. Supported on a beaker of Wynns Injector Cleaner. This is the end I kept topped up.
Once the level was static I tilted the tube and continued filling and working the wire to clean the jet.
Applied compressed air to the jet end and blew everything out. The second time around the cleaner soaked in pretty quickly. Blew it out with compressor again.
The pic below shows the little hook on the wire, at the top of the generator, which I worked back and forth while letting the cleaner soak it's way in.
This pic shows nice blue flames after I put it all back together. The red bits are the pot support stands.
NOW...... I would like to confirm this bit........ a couple of guys have said that they use 1mil of Redex Injector Cleaner to 1 liter of unleaded fuel. I'm fairly comfortable with that. It appears you get a slightly pinkish flame.
Can I add the Redex to paraffin as well to help keep the generator from carboning up ?????
One guy actually shows us how to distill the petrol to get rid of all the additives.... looks like water afterwards but then you don't have dirty generators. This is what the Coleman Fuel actually is.....but frikken expensive.
It's cheaper to keep replacing generators when they clog as opposed to buying this fuel.
