If the gap between the carburetor funnel (air intake inlet) and the peripherals is less than 4.7 inches (120 mm), the synchrometer cannot be measured alone.
In that case, you can combine the original "L" adaptor with the OEM option for measurement.
Due to the nature of this product, the rubber material on the surface may get black stained after the first time it is used.
In addition, there may be some scratches or dents on the manufacturing method, so please rest assured that there is no problem with the use and measuring process.
