Rotax engines (2) carburettor floats

Rotax carby floatsAt last Rotax has issued a final service bulletin covering replacement carburettor floats. For those not fully up to speed on this, Rotax has had a problem with ‘permeable’ carburettor floats on most recent 912 series engines. Basically any faulty floats absorb fuel and sink to the bottom of the float chamber, causing rough running and potentially overflowing fuel. Floats on affected engines had to be checked every 25 hours and if needed, replaced.

The latest service bulletins (click on the numbers to see & download): SB-912-067 and SB-912-067UL list the affected engine numbers and necessary actions.

In addition, Rotax has posted information on their blog about how to get your replacement floats.

In Australia, contact Bert Flood Imports – phone 03 9735 5655 – near Melbourne, give/send them your engine number, and they will send you replacement floats and an invoice for them. Returning the old floats quickly together with the invoice will result in a refund/credit or cancellation of the invoice.

Hopefully this will see a conclusion to the concerns over faulty floats.
