1988 Samurai. Why does the engine die going up hill?


for lots of reasons. how steep a hill, offroad.
50% grade , 99%?
is yours Carb or EFI? 1990 first EFI.
is it still stock, original engine? many are not.
many with carbs, no longer have stock carb. but have weber. as ungrade many do..
just asking for wild guessing, ?
ok, spark plugs are too old.
G(any)
engine cam belt slipped?

some are upgrade to EFI G13 or G16A or B engines.

the stock carb will be bad,, a hopeless case if ever there was... (no kits sold nor parts.)

but lets to the carb hit list.
1: choke stuck on , foods and stalls.
2: float, level all wrong, (will cause too lean or rich , rich is too high) or stuck high.
3: jets all dirty causing horrid lean state.d
4: emulsion tubes (air) clogged.
5: low fuel pressure, or too much if using a usa fuel pump with insane 15psi pressure that carb will fail. or the downgrade to electric pump done wrong. ask me if true.
5: air leaks below the carb cause lean and lack of power,
6: clogged air cleaner or fuel filter.

this is not a guess,
but each takes inspections and testing. fo find it.

Early 1952 J.D. G model- runs very rough, vibrates. runs good on pull, vibrates. Tried good different carb and dist. This tractor apparently was built of many other tractors. The flywheel was out of t


check the timing setting as it may be too far advanced ( set at 5 degrees advanced to start) check and adjust the fuel setting of the main jet as it may be too rich at idle.. You state that the flywheel was out of true and with the vibrations I suspect that the crank shaft may be bent. Something that would not normally be checked

Oil consumption


Wow.. 1967 ... 427.. I would start by checking the dist cap and spark plug wires and coil. .. this is such a valuable car you want to go first class on parts.. Performance cap rotor, plug wires like accell or better.. Bascially give it a good tune up..it is a carb car check the level of the flotes in the carbs. excess gas could be fouling the plugs.. Valve seals is a good place to look for oil comsumption.. If it is the Valve stem seals.. it will smoke when you first start it after sitting overnight or over day/.. during the night oil runs down the valve stem and collects on the top of the piston.. Last one these i rebuilt the machine shop installed the wrong cam bearings and the oil did not make up to the valve train.. had to pull motor and dissemble and replace the cam bearings with the correct ones.. seems like sometime during the year Chev, changed the location of the oil feed holes for the cam.

1982 JEEP HESITATES WHILE DRIVING AND DIES


2 things. come to mind.
i check the distributor advance works to spec with my timing light (strobe)
if that is ok, its a carb issue.

carbs fail for many reasons, (mostly gummed up inside)
we clean them. that fixes them. (with a kit)
I only have this for symptoms, and is not good.
MAJOR HESITATION AND STALLING OCCURS
does the engine have full power up any hill wide open throttle
is the Hesitation only a short time then catches up.
The carb (not stated P/N or brand) has jets, the if gummed up
will cause lean running.
so will any power valve jet.
ever tune it up. new spark pats, rotor all the way to spark plugs.
bad spark , loves to fail under load, that is its , magic.
carb>
  1. low float bowl levels.
  2. low fuel pressure causing above,
  3. bad float valve , sticks closed and starts bowl of fuel, causing #1
  4. Gummed up jets.
  5. Gummed up emulsion tubes in carb body.
  6. Choke stuck on, causing flooding,
  7. Choke dead causing hard starts . (stuck open)
  8. power valve clogged.
  9. Highspeed accelerator pump bad, causing only sight hesitation.

my guess? based on 1 word "stall" its #1 to 3 or 6.
black spark plug tips would be #6

or if black sparks, the float valve is stuck open flooding engine and stalling.

we can go for days on carbs. but will not.

I have a 1986 GMC 1500 with a 5.0 and stock rochester carb. The truck will start but you must keep gassing it as it won't idle. It kicks off every time. Any suggestions on how to fix this cold natured


fast idle speed screw, works off the fast idle cam which the choke adjustment sets, it works together by linkages. This is the raised idle speed setting you need to keep a cold engine running. First you set the idle speed by the idle speed screw with engine at normal operating temperature. Then you set the linkage up so the cam is on a raised step, throttle will be held on that raised step. then you can turn the idle speed screw to get idle at about 1500-1800 rpm. Now when you start engine cold, choke will set the fast idle cam on that raised step- when engine starts and runs it should be running at your fast idle setting. That's how it supposed to work, you just have to get everything adjusted right. I hate carburetors, they never stay adjusted right. Considering their complexity and small mechanical parts, no wonder.

Have a 90 f-250 5.8 gas burner. sat in a warehouse for 2 years. new battery and gas. starts and idles great. run up rpms for 2 minutes and it starts choking out. let off fuel and goes back to idling...


Carburetta is fouled. Run fine on choke - rich mixture. As it warms up and choke pulls off, its starving for gas.
First try adding fuel system cleaner to the gas tank. Do NOT go overboard. No more than double the recommended mix ratio.
The alternative is to remove the carb, open the bowl and spray out the jets and venturi with carb cleaner.

Its possible you may help it by removing the air filter and spraying every orifice you find on top of the carb. With carb cleaner. Be very carefull not to flood, pool carb cleaner in intake as this is not healthy for engine either. You can do this with engine running, so as not to pool, but slowly is best, both in engine speed and volume of carb cleaner.

My 84 f350 is having fuel and air problem. It ran fair but it would backfire when i let off the accelator,so I had the carb rebuilt that made the backfiring worse. So now I have replaced the carb mounting...


It seems that you have a vaccuum leak around the intake or carb, Check all hoses for good connections. You can spray carb. and choke cleaner around the intake and carb whole it is running and if the engine rise and lowers. you have a leak

My 86 f250 460 engine has hard time starting; New fuel filter, rebuilt carb, new plugs, new dist cap and rotor... i have to pump a few times, crank,,,, pump some more and then crank again for it to start


Check the choke in the carb, might stay stuck in the open position when engine cools down. After the engine is cold, check and see if the choke is closed, if not close it by hand, and see if that works.
