got what sort of problem? damage to engine problem or the environment problem?
are u sure no smoke means no carbon? Last time i haven't got a 3M, i spray my Atos
with WD40 on the TB and i saw hell of a smoke. Mom got panic and tot the car's on fire.
Later i sold off the 7 years old Atos and bought a 3M carb cleaner to spray on my 22 years
old Saga with the engine off, after spray i cant get the car started. I just followed the
instruction on the 3M, it says off the engine and spray and let it soak for 20 minutes
and try start the car, cant get the damn car to start till i need to call a pomen and
he came with his motobike, he took a bottle and get some petrol from his bike and
pour it down to the carb hole and ask me to crank. He use his palm to cover the mouth
of the carb and he do like he was trying to clear a blocked sink hole with a vacuum stick.
After a few tried, the car finally got started and i see no smoke. Weird...
Later i was helping dad to clean the carb of his 21 years old Iswara with 3M carb cleaner,
this time with the engine still running. I spray some and the engine is like dying and i rev
it a bit and continue spraying while playing with the throttle and again i see no smoke
for both the old protons while the new Atos giving hell of a smoke. Could it be the product?
