SBT Tech Tip: If your water craft is one of those machines that require a lot of choking when the engine is cold to get it started, we would recommend installing a primer kit to your carburetors. Primer systems work well because they draw fuel directly to the carburetors with out turning the engine over. Using a primer to prime your engine will prevent flooding the engine and save on extended cranking time to get the engine to fire. Primer kits are available for all types of carbs and simple to install, they are a great investment and make starting a 2-stroke ski much easier.
