I have a 1988 Samurai. I took it off roading today and while driving home it started to stall when I was driving. It will run until I punt it in gear and let out on the clutch. In order to get it home I had to pump the gas all the way home. It will run for a second while pushing the gas and then start to die and when I let off it recovers and then I would push it again. It has a full tank of fuel and was running great.

The battery is ok. It will start and run but when I put it in gear and let out on the clutch it starts to die out.

I had my carb adjusted. I mean the fuel mixture, put Sea Foam in the tank and filled it up. During the adjustment it took about 30 minutes. We took it for a drive and it did the same thing. Then we adusted the idle and fuel mixture for 30 more minutes. Now it is running great again. I took it hunting twice today for several hours and it is good. I also changed the fuel filter and check all the vacuum lines. I hope this helps and I will check the cadallic converter.

First off, it's not a Cadillac Conveter. It's a Catalytic Converter. And it is a possibility that it is plugged. I also have an '88, and I wasn't aware that the air mixture was adjustibile without completely disassembling the carb. It really sounds like you have a vacuum leak, whether it's a bad vacuum hose or bad base gasket, which is a possibility. Have you checked to see if the choke is closing when it shouldn't? It could also be in the feedback system. O2 sensor, or one of the many other sensors on the carb. Test each one according to the FSM. It's pretty easy, I checked all mine in less than an hour. OR the carb just may be BAD. Mine was.

I second JPR Ram with checking the choke. My choke sticks all the time and it is a pain in the a$$. A little carb cleaner and I'm good for a while longer.

hi,

dunno about your models but UK 1300cc models come with an aisin carb which is ****.

i know several ppl who have had problems with the carburettor including myself!!! sometimes the choke plate will get jammed which either causes the idle speed to stick at about 2500-3000rpm! other times the engine will just cut out. its very hard to slow down for traffic lights and keep your foot on the gas to stop the engine stalling at the same time!!!

if you cant find a fix, take your airbox off and fiddle with the topmost butterfly... it should be spring loaded and should either close or open by itself. if it gets stuck or the spring is broken, try taking the butterfly plate off and see if it fixes it... its only 1 bolt for the airbox and two screws for the butterfly so its worth a go... its a good fix but makes it a pig to start in the cold!

otherwise i would check your fuel filter (should be just on the inside of the chassis, fuel filler side)... some people also put extra fuel filters in between the fuel pump and the carb

good luck

plugging

this sound like a fuel plugging problem. check filter, pump pressure and flow. then check carb for plugged ports. the inlet for the accellrator pump is at the very bottom of fuel bowl and if there is fuel flow problem there may not be enough fuel in bowl for main metering circuit but accellrator pump will still work. or if the main metering port is pluged, you woud have same symtom.

A plugged cat could cause a simular symtom. to check for pluged cat . use a vacuum gauge. the vacuum will drop very low when rpm is raised or attach a pressure guage at o2 hole. reading should be no more than 2.5 psi at 2500 rpm.

I had a similar problem on my 88 Samurai, 1.3 and chased all of the above things, vacuum lines, mixture, fuel pump, fuel filter, Sea Foam in the tank, plugs and in the end it turned out to be the fuel mixture solenoid in the carburetor. New one and all of my problems are gone. It has been running great for the past 6 months. The solenoid was sticking and it ran like crap. Idle was OK, but no power.
