Suzuki df2.5 fuel pump

[Billows]

I have determined that mine is a 2012 model. I have looked up the assembly detail diagrams from Browns point.

This indicates there is a fuel pump but I can't see it on mine. The cock seems directly connected to the carb

I am attempting to clean the carb also

I have taken off the cover ( 20). I assume I undo the screw (16) I can see proud of the surface to take out the pilot jet (15) for cleaning. Will the jet just fall out or does it need unscrewing too.I can also see two small brass coloured items inserted in the surface which I assume are (17) air jet and (18) pilot air jet. What do I do with these. I will also take off the bowl to clean the main jet (3)

Hoping this will cure the slow idle cut out and the occasional falter on full power. Spark plug is a nice biscuit colour. I also know about the hidden low running adjustment. I may access that also.

Definitely no fuel pump on my 2013/14 DF2.5 as I had all the fuel pipe and carb off in order to fit a proper fuel filter when it was brand new ...... hopefully to ensure that I never have to clean the carb, so I can't help with that bit I'm afraid.

What fuel filter did you use and was it possible to cut and use the existing fuel pipe?

I bought these: http://www.ebay.co.uk/itm/5-x-Small...ke-Quad-ATV-/141628932479?hash=item20f9be017f

Make sure you buy the filters with an overall length around 50mm. There are a lot of adverts for a very similar filter which looks the same in the advert photos but is around 100mm overall length. I originally bought the 100mm version but it is really too large for the space under the DF2.5 cover and difficult to install. The 50mm filter is fine for the throughput and very easy to fit and replace when necessary.

I bought a length of nominal 6mm ID fuel pipe: http://www.ebay.co.uk/itm/Nitrile-R...Tubing-Breather-/130740225601?var=&hash=item0 so I could extend the pipe from the fuel tap to the carb and simplify the fitting. This was essential with the 100mm filter so I left it in place with the 50mm filter.

However, it might have been possible to fit the 50mm filter without the extended pipe by simple cutting the original pipe and inserting the filter ...... but I think it will be very fiddly and would make checking the cleanliness of the filter and replacing it a 30 minute job rather than a 30 second job.

Make sure you install the filter in the direction such that the fuel flows from the outside of the element through to the inside of the element as this makes possible a quick visual check to see if there is any sediment in the filter.

There is a load of stuff on the internet about these crap engines. eBay helped me cure mine, I bought a secondhand two stroke Mariner, works perfectly.

If you want to buy the lightest and quietest 4 stroke outboard ever produced ..... the Suzuki DF2.5 is your baby!

Great little engines.

How did you get the top plate off your carb. Mine is held in place by the choke and throttle assemblies, which are riveted in place. The plate is loose but won't come off!

 

[Tam Lin]

Don't worry guys, I found out how to do it on an American site, take the choke plate off and the stem pulls right out leaving you room to get the plate off! God bless the Internet!

Thanks for reminding me of the only two redeeming features of this accursed engine.

I can sit on a marina pontoon or the open transom of my yacht and hoike this engine from pontoon to dinghy transom in a single movement without a safety line or engine harness due to its low weight. One day soon I expect to adopt the stance of an Olympic hammer thrower and project my Suzuki 2.5 20m into the nearest river, that will be a glorious gold medal moment for me.

I felt the same way about mine but don't give up on it yet! I followed the advice on another thread and drilled out the jets in the carburettor yesterday. The motor started first time, even with old petrol! I ran it in a dustbin for about fifteen minutes and it didn't hesitate when I revved it up. Of course the true test will be when it is on the back of the tender but I am hopeful at the moment!
