Well, the transformer came today to replace the one damaged by 240V. I installed it but the furnace would not work! This was strange because I tested the furnace with a varyac transformer at 24 volts and it worked perfectly. The new transformer puts out 27 volts, so I thought maybe that was the problem. This is what the furnace did. The draft blower comes on, then the igniter lites the pilot lite and then the burners don't lite and the furnace shuts down and gives 6 blinks, pause and one blink. I looked up the code and it says soft start fail. So then I tested the flame sensor and it is 18 ohms. I then tested the voltage on the two blue wires which I think are for the flame sensor. Anyway 4.5 volts appeared and walah! The burners lit up! So I guess the flame sensor is bad? Anyway I left the voltmeter hooked up so the furnace would work and ordered a new igniter and senser, $24! Why didn't the furnace flash the code for a flame sensor? Did the extra voltage burn out the flame sensor? Why does the furnace work with the volt meter hooked up? It's crazy!!! I have to wait till Jan. 15 for the igniter and senser! Will the extra voltage burn out the new sensor?

But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
