I certainly wouldn't rule out a fuel restriction, either in tank where fuel drains to line, or line(s) to carburetors. When cold, more fuel required, plus once engine starts to run, vacuum from carbs may overcome restriction, as well as less fuel required. My guess is that heavy acceleration is a problem even when warm as well. Doesn't take long to check in tank to see if filter/screen in tank is plugged at all, as well as remove fuel line for carbs and use compressed air (carefully) to clean out line(s) as well as blow back into tank to dislodge debris at screen in tank, but if there is debris, remove tank and flush good. Any in-line filters should be replaced as well.

Cold start


TUNE UP TIME. I-6 engine?
old spark parts JUST HATE water.
100 years, of this and same.
do the 60,000 mile tune up, called the service schedule. lost it?
we have it
cap ,rotor,wires, spark plugs, filters,. fuel and air.
i bet it runs now. (for sure, it has great chances)
id also check engine compression. for 150psi x 6 w.o.t.
mine, loved to crank the Exhaust manifold , and cause the
O2 sensor to go nuts. (but is not related to cold starts)
the cause was a broken exh, clamp, below the bell housing,
making the exh. pipe to wag like dogs tail, bending header and cracking it(mine had nice SST header stock)
that was the only bug in my jeep. I6
other than the monthly ISC sticking and cleaning (IDLE out of control)
i cured it. (ask)

My 2005 honda civic is not producing heat only blowing cold air


Check that the heater pipe are hot, there are 2 pipes 1 in and 1 out. if both cold could be stat .If 1 is hot and the other is cold it could be air or blocked heater matrix, with car running take cold pipe off . if water flows out check its warm, if it flows out cold leave till water warms up then put pipe back on, make sure you keep radiator topped up while your doing it, if no water comes out when you take the pipe off the matrix is blocked, take both hoses of and flush through with a hose pipe.

My 1983 Nighthawk does not have spark while pressing the start button, but has spark after releasing and engine turns nother round. what could be the problem here?


This is a motorcycle question. Repost in motorcycles.

If it is like older electronic ignitions, it has a start and a run section. The start section can fail and the run section will still be good. Will it push start or does it have a kick start? Been a while since I had a bike.

1983 honda acc cold start wont stay running when cold idles rough


try checkin your idle air control. most of the time it is a vacuumn line going into intake.pull it off and if the car revs up dont worry, it wont hurt it. if it does simply put it back on, if it dies you have a bad vacumn.
