sprayed out the idle stabilizer valve (or whatever they call it on a mercedes), and the throat and flap of the air intake, wouldn't start right away but after a few minutes it did, and stayed lit until I stepped on the gas, re-lit right away and after 2-3 of these I was able to apply the gas and it stayed lit.

turned it off after five minutes, drained the radiator by removing the hose near the pet-cock, took a while for the draining emulsified to dwindle to a thread. re-attached the hose and added citric flush; ran that with water for about ten minutes, then the engine died...it would re-light but only for a couple of seconds. drained flush and added just water, but wouldn't re-light (for more than a second or two).

letting it sit and cool for a while. I left out a step (in my description), which was a first flush with comet liquid cleanser (only active ingredient citric acid), which also ran for ten minutes then died, but also blew a hole in the lower radiator hose (from radiator to water pump)... took out the thermostat, cleaned a little mayo off it, boiled it in pot of water, saw that it works okay, turned on the car with the water pump open, and saw the water pump's working okay also, noted liquid inside was like thin motor oil, added water till over-flowing and it looked less oily.

problem now seems to be shutting down after idling for ten minutes, will google the forum for possible causes, but guessing something to do with air flow when it gets warmed up.

???
anyway, my ride to the train station down the tubes
ezip scooter blew a capacitor in it's controller, so that's toast for now
at least i have money for the bus and train, but will have to walk a mile and a half to avoid taking two busses to get to the train, sucks. hehe
