Hi zerosvarka, Heat sink looks better, should be Aluminium or Copper, steel is a poor conductor of heat. You should have somewhere for that big old spark to go, put a plug wire into it attached to a sparkplug and ground the plugs outer shell, think where is the spark going now, if it flashes over to the side the transistor is on it's time to practice replacing it again. ! more thing, the coil looks like a used unit, how much current is the primary pulling, and do you have a current limiting resistor in the primary circuit?

If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves
