Who leaves petrol in the Carbs ???????

The guy I got my RIB from advised me to disconnect the fuel line after flushing the engine and let the carbs run out of fuel. He did this after every use. What do you lot do ?????????? Any advice would be appreciated.

Hi yes as far as I know as long as you are premixing the petrol oil mix then I would as ways run it dry!
Do not do this if you have a direct oil system as the oil will still be fed when the petol has run dry!

The YAMAHA engineer said to me when we had the same discussion that this is OK with the old carb (Yamaha) engines but is not good for the new 2 stroke and HPDI engines as well as the 4-strokes engines.
He said that is best to open the little valve under the carbs and flush the carbs out.

Do you run your car or bike out of fuel everytime you get home?

If you are using you engine say every week there will be no problem with fuel in the carbs. The only time you may need to drain them is if you have pre-mix fuel and are not going to be using the engine for a month or more.

Yes Tue you are 100% right! I ment to say if you leave the engine for long periods of time (say during the winter months)
