Packing Insulator / Inner Carburettor Gasket – Honda GX390 Go Kart Engine - (Pack of 10)
Complete the job — buy it as a kit
Aftermarket replacement packing insulators for the Honda GX390 go kart engine. Also known as the inner carburettor gasket, this is the seal that sits inside the carburettor assembly itself — keeping fuel circuits sealed and preventing air leaks that play havoc with mixture and idle quality. It's a small part that has a disproportionate effect on how cleanly the engine runs when it starts to deteriorate.
With E10 fuel accelerating the wear on carburettor components generally, it's worth replacing this as a matter of course any time the carburettor is stripped for cleaning or jetting. At this price with a pack of 10 on the shelf, there's no reason to refit the old one.
