Bad Luck with Sammi

Since the last time I posted, I have NEVER gotten my sammi to run correctly...after taking it to 3 different repair shops and installing over 3 different carbs (one bought new for 389 bucks!) I've finally come to the conclusion that I wasn't destined to drive one of these things...Damn repair shops here in Green Bay suck (I blew over 600 bucks on nothing)! Nobody seems to know anything! If anyone can refer me to a reputable shop in WI, please do. Or if anyone is interested in a 87 sammi with a new sprint top and carb, let me know...

Re: Bad Luck with Sammi

toss the stock carb and all the vaccuum lines and electrical junk that goes with it. Get a pony carb for $90 and bolt it up.

No more worries about stupid carbs. Do a search on POny carb and you will find 100s of posts to read

Re: Bad Luck with Sammi

Exactly what is it doing? You might be changing carbs only for it to be a completly different problem. Out of curosity, have you had the valves adjusted? What can seem like a carb problem, can just be incorrect valve settings.

Re: Bad Luck with Sammi

Please tell us what exactly it is doing, we can help, but we need to know what ails you zuki. The carb is only one of 10,000 possibilities it could be. If the carb has been rplcd 3 times, maybe something else should be looked at? Usually I have found that it is something very stupid, but completely overlooked. Are the vacuumn lines hooked up correctly? stuff like that. Tell us and we WILL respond! [img]images/graemlins/40BEER.gif[/img]

Re: Bad Luck with Sammi

What happens is that it starts out fine but once it gets warm, it won't stay on. All three repair shops went through and replaced all vacuum hoses. I had the exhaust and intake manifold replaced at the last repair shop. It helped but the engine still stumbles and misses at idle...not to the point of dying but pretty darn close. All three shops told me it was carb problem. You would think that if you brought it to an ENGINE REBUILDER, they would check valves and compression...So i assumed it wasn't an engine problem. Lights also don't work now for some bizarre reason and wipers won't park. I had that thing replaced this summer and now its bad again...I also had a huge problem with the fusible link blowing this summer..maybe thats the part of the problem too..something electrical? I wish there was a knowledgeable samurai owner around my part of town...thanks for helping.

Re: Bad Luck with Sammi

(starting playback of standard answer given a hundred times already)

Redo ALL your grounds, even if they look good. Create new, thick grounds from your battery neg post to your frame, from the frame to the body and from the frame to the engine, preferably all from the same gigantic self tapping screwbolt driven directly into the frame. Check the ground from the distributor to the firewall and redo it. Check the grounds in the back of the truck near the tailights..the wires are probably all crispy and black and falling apart.. Check the grounds from the lighting to the bodywork and redo them.

I read that your previous issues were electrical and in my opinion they still are. Samurais don't have electrical systems like regular old american cars. When you get one ground that is bad, it can screw up a whole host of seemingly unrelated things.

On my own sami, I had a collection of weird issues with the lights, the interior lights, the radio, the battery draining out, etc. it was ALL related to bad grounds. I created a "ground octopus" as described above right from the battery down to the frame rail and branching off from there to the body and the started mounting and all the weird issues went away. On my tracker, (which is also suzuki-designed) the wipers would go on when you turned on the blinkers. It was traced to a body ground from the lighting harness which wasnt complete because there was body work done and the grafted-in inner fender and rad support weren't grounded like the rest of the body, so it allowed a floating ground that tied into the blinkers and the wipers and the lights, etc.

Re: Bad Luck with Sammi

feedback carbs can be a real pain. most shops around here force the car owner to sign a waiver before attempting to rebuild or repair a feedback carb. this is done to cover the shop's ass since most of the time they can't get the feedback carbs to run 100% correct. it is usually not the carb itself that is bad, but one of the electronic componants either in the carb or somewhere between the carb and the carb's ecm.

my buddy dumped about $1000 into a mazda 4x4 just having the feedback carb repaired a few times (each time he was forced to sign a waiver form)and it still ran like pure ass. he traded in the mazda taking a huge loss on it. having low miles on the truck and very good compression numbers, a non- feedback carb may have been the ez fix.

burned exhaust valves are very common on these samurais and bad valves will bring out a poor idle as well. compression and vacccume check should tell you if the engine is sealing good or not.

Re: Bad Luck with Sammi

One other thing you may want to look at is the smog system. On carbed Zuks the carb and all the crapola attached to it are an intergral part of the emmissions system. A bad PVC or EGR valve can cause a whole world of problems.
