Hola a todos.
El otro día encontré un pequeño artículo de 3W que me parece muy interesante y viene a decir, si no me equivoco, que la temperatura idonea de de funcionamiento medida en la culata, justo al lado de la bujía debe ser en torno a los 250ºC, a 300ºC existe riesgo de rotura del motor, y a 200ºC se creará carbonilla impidiendo el correcto funcionamiento.
Os dejo el articulo
"metal gasket ring of sparkplug has to be removed and has
to be replaced by a copper ring 1mm thick. In this ring, you
have to drill a hole dia 0,5mm. In that hole a thermo element
has to be soldered in. This prepared copper ring can be
connected now to the temp. gauge. Using this method the
optimum temp. for air cooled two - stroke engines is approx.
220 - 270 degree Celsius. In this range the carbon will burn
off without remains: the top of the piston, surface of combustion
chamber and spark plug. The colour of the spark plug should
be light to medium brown. Temperatures above 300 degree
Celsius will get critical for the engine. In case the temp. will
climb to 400 degree Celsius piston could seize. Temperatures
below 200 degree Celsius will build up carbon on top of the
piston which is dangerous. With too much carbon, the piston
can hit the top of the cylinder. and that causes problems:
The engine starts making noise, power drops and if worth
come to worth the connecting rod and crankshaft can be
bended
checking cylinder head temperature
