She'll, (the samurai) will run pretty good but won't idle. I'll get it sorted by and by.

still sounds like the Idle set screw is just set too lean . they can sometimes back off or the throttle cable could have stretched.



I hear you on lean condition but don't see where throttle cable comes in the picture

it shouldn't but it connects to the throttle linkage. so I threw in being slack in as well. as something you could check. thinking on the off side, it might be letting the butterfly close too much.
it was a long day.

Just came across streams for the Green Hornet TV show and its movies.

The car is known as The Black Beauty and boy she is a beauty.

Talking to a young lady the other day I mentioned that my first car was a V8 Oldsmobile. She said she didn't know Olds ever made a V8. I said, "you never heard of the "Rocket 88"?" She just gave me a blank stare.

so donnie?? how goes the battle? any closer tofinding the idle issue?

talking with some of the tuner guy's and they were lost.
dint understand what a mechanical fuel pump was.. aand knew even less about carburation then I do.
if they cant tune i with their lap top. they are blank slates.

Stuck the carb back on and poured some gas down the gullet and it cranked but now it seems the fuel pump is not picking up. Didn't dig into it much yet. I do appreciate you trying to help for sure !

they thought a V-8 was a big block and a V-6 was a small block. LOL.

ahhh. that may have been your problem all along. your fuel pump was going out. that would make it run lean too.

with a mechanical pump it sometimes takes some cranking to get it primed. May also be clogged filter or line.

the seals sometimes go out on them.. and if it is an older pump. ethanol will degrade them.I had to replace 2 of mine because they no longer worked. and now my other monte carlo's pump is starting to leak gas. so I'll be replacing it next.
newer rebuilds are switching the rubber to poly urethane. to solve the problem. of modern fuels.

Mech FPs need to be primed and keep the prime.
To eliminate the lines, put some gas in a glass jar and hose it to the pump inlet. prime it and see if the engine starts and drains the jar.
If it stays running till the fuel is gone, the problem is someplace in the pump inlet line from the tank.
Also check the tank vent to make sure the tank isn't getting suction locked.

Sample Pump


I've seen people install inline filters backwards before and it results in engine not staying running or stalling (if put at a certain angle which causes a void).

One other option is to buy a cheap inline electric fuel pump and bypass the mechanical pump, if the problem goes away, replace or rebuild the mechanical pump.
If the problem remains, the problem is not likely to be the fuel pump.

If there's dirt in the lines or the pump - check the pickup sock in the tank.

Changed fuel pump out for one that I THINK is good and ran a length of hose up a ways and filled it with gas. It ran but still no idle, may have been a bit better but may have been wishful thinking. I have an electric pump that I actually was thinking of putting on. Probably try a jar in a sec

Fuel but no idle indicates a carb issue.
Look at the float settings and the mixture screws.
If automatic - check the anti-stall dashpot.

Before replacing the fuel pump run a jumper line thru the electric as a temp to check.
If it idles fine and stays idling, problem is the mechanical or the line connections.

If you don't have pipe thread fittings to hose barb you can cob one up using an old chunk of heater hose with band clamps to a smaller tube till it sizes to the elect pump fittings.
Like a step up and step down bushing.

Some mechanicals have clamps on the inlet and a fitting on the outlet which uses a steel pipe to the inline filter with a clamp.
Some without the inline filter have a steel pipe to the carb bowl inlet filter housing.

Throw an inline fuse in the elect pump wiring and use jumper clips to activate and deactivate the pump. Just remember to allow the bypass to prime.

If you pumb into the tank suction line, it will run as long as the elect pump is active (an there is fuel in the tank).
If it still won't idle, could be the carb or the tank/lines if a fuel issue. Might be other things tho. Make sure the distr primary is good, points/ground, no intermittent shorts.

If it stays running off-idle (low cruise circuit) but stalls as soon as you return to the idle circuit check the mechanical linkage and curb idle setting. Try screwing the curb idle up a few turns to see if it stays running, then rev it up and let it fall back to idle and see if it stalls.

Looks like I have a carb problem. Had it running from jar and had a half decent idle for a bit but runs extremely rich. Sucks down 12 oz. + of fuel in like 15 seconds.

donnie, at this point, I normally would adjust the Idle and float screws good enough to get it running in the ball park. then take it to a shop to have it properly adjusted.

Are the mixture screws accessible or do they need drilled?
Have you had the carb apart?

Two things right off cause rich mixtures...Choked air flow or excessive mixture (assuming you have the right heat range spark plugs and ignition timing is correct).

Choked air flow
-Throttle plates misaligned
-Clogged air filter
-Collapsed ducting
-Choke plate stuck

Excessive mixture
-Idle mixture screws out of correct adjustment
-Float out of adjustment
-Bleeding secondaries
-Float seal damaged
-Mixture screws or seats damaged
-Fast idle sticking or out of adjustment
-Curb idle set too high

Its nearly impossible to troubleshoot without being there. Its why I give so many items to check. Common stuff I used to see when I was working on gassers.
She'll, (the samurai) will run pretty good but won't idle.


Is this your carb?

-carburetor tune-up
-Stock Carburetor Float Weight
-She LIVES!...more or less...idle question
-stall at idle
-Please help me with a carburetor vacuum tubes !
-carburettor problems
-high idle while warming up?
-the car wont idle slow

I looked at two forum pages and found those threads related to carbs for a samurai/suzuki
If you look you might find more or better.

Or park it out in the pasture and unlimber a few rifles on it so it can never bother anyone again except the scrap man !
