"Venturi Tube
If you are running a stock carbureted motor, you have a easily fixable problem. Suzuki should have put this part in from the factory but caught it to late. "...Samurais may exhibit a hesitation/flat spot, in any gear, when in acceleration from partial to open throttle." Your Samurai has or will have a flat spot in carburetor. When you are at an idle and you floor the throttle it will hesitate for a moment and then continue to rev up. That hesitation is what you want to get rid of. The reason for this is it causes a vacuum in the fuel bowl. This venturi tube catches some of the air coming into the engine and forces it into the bowl eliminating the flat spot. Super easy to install and only takes about 5 minutes.
Price: $11.00"
Now I never had a drama until I had my carby (stock Aisin) rebuilt and tuned just recently. I put it back on and the gasket leaked so I pulled it off and cut 4 x gaskets out of gasket paper (two for each side of spacer) along with plenty of goo to ensure it would hold and it has, no dramas.
But now when I go to accelerate I have a noticable flat spot for at least a second. Both when taking off from neutral and when accelerating from coasting in gear.
It happens at low RPM (~1000rpm) and doesn't occur anywhere else in the rev range. So is this what they're talking about? It never used to do it at all.
Would like to get it sorted in the next couple of weeks before I leave for Fraser Island. Can you buy this part locally anywhere or is it worth getting them to airmail it over to me?
