i dont know what to do.
stock samurai carb, when i go down a bump road it feels like it gets flooded, never had the prob at sea level but now that im at ~7000ft it happens.
anyone dealt with this or know how i can fix it?
*BONUS* Tech point for the person that helps me fix it :P
Thanks

TBI will fix it. I used a 1.6 valve TBI and had a harnes made from a complete 4 piece unit to a stand alone for my 88. Works great.
-
Have u found the little air adjustment on the right side of the carb? If adjusted rite these little carbs are great and wiill perform better than most Webbers.
-
whats a TBI? before i put all my stuff on this didnt happen and now on the same trail its doin this. Ill try turning that air adjustment
-
TBI : Throttle Body Injection
-
I have also been told that if i play with the float that could fix it...
-
True, I might just be getting old or lazy,but to me start and drive with not having having to worry about angles, float settings,choke sticking. Is much more enjoyable than having flooding issues and such. But that's my opinion.
-
I appreciate it. Where should i look to get the harness for that TBI you have? how much would you want for it?

No reason your carb shouldn't work at altitude. When you say " put all my stuff on " what exactly do you mean? Did you mess with anything electrical? It does sound to me like you've got a float bowl either starving or flooding, check the float level,needle and seat.
Did you obtain this vehicle from a high altitude part of the country? You may just need to re-jet your carb, or do as the others have suggested and adjust your float and idle air mixture. Messing around with carbs isn't rocket science, there's a method to tuning. Once you get the correct method it applies to most normally asperated, carb'd engines engines.
I have to agree with Zuki Girl on this one though. It's probably gonna be easier, and have much better all around results by switching to a Throttle Body Fuel Injection off any old Trackick 8 valve. Grab the intake and everything from there up including the wiring harness and ecu.

got vehicle from Dallas 7 ish years ago, never had a prob till now. happened last night on my way home from work, sat in front of a restaurants deck full of ppl featherin the gas and backfiring for 5 min... ya, im smooth haha :-\
-
would a fuel pump solve this problem?
-
You need to check the fuel pressure before you start replacing parts. Did you check your float ?
-
havent checked the float. kinda paranoid if i start takin stuff off it wont go back on. and apparantly noone in any of my circles around here know anything about carbs enough to watch over my shoulder and tell me if im doin right
-
so over the weekend i finally got to take a look at my chilton book and my rig, first off, that book sucks!! i had no idea what i was lookin at. how do i get to the float? how do i know if its bad or needs to be replaced?
-
there should be a little window on the float bowl so you can see the fuel level.
also - there is an altitude switch that tells the computer to change the fuel mixture control valve function at high altitude.
the fsm has good trouble shoot/inspection of these items(my fsm is for a different model).
the carburetor is a real pia to take apart- look at everything else before taking it apart.
-
i wish i had the fsm
-
my situation was with an '89 carbed kick, and the carburetor is slightly different, but i believe the system works the same. the chilton i had was way to sketchy and i sprung for the factory(the section on the carburetor and emmissions was a supplemental) manual.
i never would have figured it out otherwise.
also need a good VOM.
if you disconnect the high altitude sensor(HAC) and bridge the terminals, it should think it's "high", but it would be best to be able to check all those sensors and switches to confirm function.
all that stuff(o2, temp., throttle switches, etc.) works together thru the ECM(computer)to control fuel mixture.
sorry i can't be more help.
-
Thats great help and i appreciate it, i think it might bee too good lol. When it comes to the engine i need "grab the red wire with the white stripe and plug that into the opening above the blue wire" kinda thing which i hate admitting to but thats how it is right now
