Smile dies everytime i hit a bump gas!!!!

My SJ410 had an AISIN Carb installed when I bought it. Not sure if its the same for yours. Here's a little past experience I had.

Checked the fuel hose connections and make sure nothing is loose. Use a hose clamp if necessary, its cheap and just to be sure.

Are there any tears around the connecting end of the hose to the carb? Change the hose if required.

Also, there's a "float" inside the carb that controls/limits the flow of fuel into the carb that you might want to check. You might want to check the float/lever to make sure it's working properly or the carb would overflow and thus fuel spilling out all over.

About the Engine dying suddenly, you might want to also check the mini fuel filter inside the carb for impurities/blockage. Mine had similar problem till i had the filter replaced.

Hope this helps.....Good Luck.

If the internal filter is clogged, it blocks the fuel from getting into the next chamber where air/fuel gets mixed for burining. In simpler terms, fuel supply to the engine gets suddenly cut off, so, no fuel = engine dead....sorry, not a trained mechanic, don't know the proper part name P

When that happens, you get an overflow where the fuel would spill out from the air intake hose.

hehe, maybe we're separated by a comon language...when you say "rebuilding", i assume you mean repair/replacing internal parts right?

in my case, yes, it fixed all the problems. start-up, idle, rev up = ok, fuel spilling all over, engine dying whenever i put into gear.

you might also want to check on your fuel filter, usually located on the hose near the fuel tank. just to make sure it's not clogged up as well. It's a white semi-clear plastic. cheap but important as well. (see photo)

Get one that is made of clear/white plastic, easy for your to check if it's dirty/clogged and needs replacing. You could check out this link.

eBay Motors: Fuel Filter, 85-88 SUZUKI TRUCK All Models ( 4-1300 1.3 (item 110243470335 end time Apr-19-08 19:53:00 PDT)

It's installed along the fuel hose between your fuel tank and the carb. Usually near the fuel tank, so you may have to get under the chasis to check.

I had mine moved from below the chasis (near fuel tank) and placed under the hood near the carb so I didn't have to crawl under everytime i check.

Check the gasket where the float is.
