Unburnt gas smell from the exhaust

buy some new spark plugs. then install them.

 

Every morning when I start the cold engine of my old Honda, especially in
the winter, the car started hesitantly and I can smell the unburnt gas. To
keep the engine running, I have to keep pressing the gas pedal until rpm can
itself sustain at 2k to 3k. When this car is new, the process took about two
minutes and I don't need to press the gas pedal, now it takes five minutes
or longer in cold days. The car acts normal after the five minutes of my
morning blue is over. Also, the emission is somewhat blackish in that first
five minutes. The emission turns to normal white steam after the rpm hits 3k
then drops to normal 1k instantly. Does anyone know what causes the problem,
and is it expensive to fix? Thanks.

 

maybe a dist.cap and rotor,new plug wires....
and run some dry gas for a few tankfuls.
it would be nice to know more about his Honda is,;year,model,mileage,etc.
Essential,really.

I see this was posted on Psychic Wednesday . . . .

All we know: It's not a Honda motorcycle. I guess we don't care which
side the steering wheel is on.

Do a tune-up run a bottle of fuel injector cleaner through it and stop
warming it up on the driveway. Also search Google for 'italian tune-up'.

Start it, adjust the mirrors, and DRIVE.

Hmmm,
Time for a tune up.
