1600 Escudo Jet Size

[IndoJohn]

A friend has a 1600 Escudo which has been repaired but we think with a carbutteror from an earlier model and now it runs very rich at idle and at medium speed.

Does anyone know or have a manual that can tell us the correct sizes. That will get us part way there. The next quest will be to find them:-)

He is an ex sidecar racer and I used to race stock cars so we do have some mechanical apptidude between us.

Any help will be appreciated.

UPDATE

The engine is a G16A (1600 cc 8 valve, with carb; the 1600 has fuel
inject, twin OHC, 16 valve and diesel variants. Big confusion is the
model name, closest to mine is the Nth American sidekick 1996-8

A whole carb is a later option, don't want a carb that fits but is
kitted for a different hp engine. The carb kit avail here is for the
earlier vitara, all the gaskets line up but that carb has brass float
with adjustable tab for fuel level. My carb has nylon float block
assembly, no fuel level adjustment. I will try spacing the float value
with a shim to lower the fuel level 1 mm, see if it works without
starving the main jet. Maybe the original float needle was a fraction
longer than the replacement kit one? I could try lengthening the needle,
but the simple solution is crank down the idle jet 1 size. The
background is the carb micro-filter has progressively clogged over the
past year, gave the engine pretty much the right fuel supply except for
sudden acceleration. Now I meticulously clean and reassemble car, the
rich problem is much worse, definitely too much gas at the fast idle &
transfer up. Gives me something to do, pulled the frigging thing to bits
6 times.

IndoJohn,
My thoughts; have you checked the fuel pressure?
Where is the float level when you pull the carb top off or does this carb have a site bowl?
Do you have access to "sniffer" to check what's coming out of tailpipe?
Also is there a good squirt of gas when you open the throttle and is dizzy advance working correctly?
If you need to try jet different jet sizes and can't find any,fill and drill old one.

id the car first
what year, what engine , 1.6L , number of valves.
the might have a VIN number but in your cas (totally guessing non USA , Canada, that your car has a body tag.
the last line on the tag is a build code.
posting this code , exactly id's any car made outside of usa (delivered actually)

i have someone on this board sending me photos of these tags.

you you stated what country you are in , that would help too, as in EU, there are many carb models ,used up to 2000 year. (unlike here, usa)
ok tell us what you really have.

cheers

now to your question in general.

is the choke unloading, ?
get engine hot,
look down bore.
choke plate must be full off (100% vertical)
if not it will run rich all the time.

chokes are 100% #1 first line failure on carbs.
#2 is clogged jets, and
#3 is gummed up metering needles that can stick up and make carb run rich.
#4 is air tube inside clogged, this makes carb run rich. (all air tubes must be clear)

more accurate data if you can ID car.
i have some exploded drawings of them. (the many)

truth is most carbs can be made to work sans parts.
so long as you dont break a gasket.

Thanks for the reply i am doing this as a proxy as my friends company server will not allow forums.

I do know it is an 8 vavle 1600cc Escudo, purchased/made/assembled and driven in Indonesia. I believe the engine originates in Japan. I don't have the VIN or engine number.

I will pass on your info from your second email. Cheers.

i confirmed your belief.
it is not asia market car as all have injection.

open hood , top left on fire wall is a tag.

5 lines.
line 2 is VIN. (veh. Id. Num)
line 5 is market code. 9 digits and last 2 are market code

all data is important but that last line is critical to get the correct parts.

cheers.

attach.
is just 9th like decode.

you may have a JAPan E01 car, this the Base car. no Smog options for other countries. is 01.
but that is a guess. your car could be any market car ww.

good day.
