    Re: Ignition Circuit

    Ok bit of an update!!!!

    Got the new starter motor and a new battery and some new connections......

    Boat now cranks, starter engages and flywheel spins.

    But, no firing.....

    I check compression and I am getting 115 and 119 roughly, getting spark from the spark plugs, I have fuel but just no bang.

    Am I just cursed?????

    Re: Ignition Circuit

    I bit of history might help too, is the motor new to you, why were you compression testing, how did you test for spark, how did you test for fuel, how did you try & start it etc?

    Re: Ignition Circuit

    Hey, I got her firing and running YAHOOO!

    But alas its not meant to be, she is running like absolutely crap.

    Whenever you move from the fast idle lever to accelarate the boat just stalls.

    If you jam the fast idle up to choke full and then quickly back of and accelerate you get a bit of a put but nothing else.

    Had a bit of oil coming down the leg and a bit of petrol hanging around in the water.

    Bit of history, I only bought the boat a week ago and water tested it and it was running fine. Age old story got it home went to compression test to check it out and then everything that has happended has started since this compression test.

    For me I am done with this boat, only bought it a week ago with hopes of getting through a season in it and repowering the old girl but now I have locked it up out the back and don't even want to look at again!

    Re: Ignition Circuit

    Well you've got compression and it was running fine a week ago so there shouldn't be much wrong with it.
    Fuel & oil running out is only unburnt fuel and typical of a cold cranky 2 stroke.
    At your current rate of progression you should be good to go by tomorrow night.

    Re: Ignition Circuit

    hahahahahahaha love your positivity fed

    I have now laid down the tools!

    I am looking at two options now with the impending trip coming up....

    1) Getting another tinnie / inflatable for this trip

    2) Getting the marine mechanic back out to check everything.

    The only reason I am hesitant to do any more work to it is as to purchase any part for this motor they are either non existent or you are paying $$$$$..

    Its already cost 1k today for a bloody starter motor and battery. I can spend anymore or may as well just buy another bloody motor.

    I am also a bit suspect on the coil packs to, they are working but not positive on their condition overall.

    I went looking for a coil pack replacement and Suzuki strikes again and nothing can be found for the motor without importing it into the country or paying suzuki premium prices and waiting a couple of weeks for them to arrive............

    Re: Ignition Circuit

    Sounds like it's barely running on one cylinder!

    Put new plugs in, drain the fuel bowls on each carb, then prime the fuel bulb to flush out the crap fuel put the drain screws back in. prime the fuel bulb again and see if it goes tight and you can no longer prime. Put fresh fuel in the tank and see what happens.

    Let the motor idle for a while to heat up then gradually increase power until the motor is warm and burn't off some of that oil sitting in the crank case, then run around 1500 Rpm for 10 minutes.

    Good luck with it.

    Re: Ignition Circuit

    Cheers mate, that's what it felt like one cyclinder...

    I did put new plugs in after I got her running as the old ones looked pretty crap.

    As mentioned I am suspect on the coil packs but can't get them easily.

    Will check on monday if anyone has them.

    Re: Ignition Circuit

    If you want to throw parts at it then a genuine Suzuki manual would be the most cost effective, then you could test the coils and be happy.

    Re: Ignition Circuit

    Nah your doing something wrong here I'm just guessing but your motor has electric solenoid choke as all DT 60's circa 1983 - 1984 have.

    To start your motor push your key in!!! not turn it! you should here a click from the choke solenoid under the engine cowl once you here the click! turn to start the choke will stay on full by itself for around 10 seconds if the engine stops push key in to choke again. Like I said two bangers need there choke and they need plenty of fuel until warm.

    That there lever you mention is just the warm up lever no choke involved with that there lever.

    You don't have to start the boat to here the click! and with the cowl off you can see the solenoid move the choke linkage.
    Don't give up yet !!!!!!

    Cheers.

    Re: Ignition Circuit

    OK multimedia ausfish boat testing is about to happen!

    I put the tools down and the boat away but I couldnt resist another tinker.

    Went outside and low and behold first kick she starts up nice and tough, idles a little rough but putting it into gear and accelarating caused no stalling.

    Well ill be buggered as this is not how it was behaving at the boat ramp.

    I have a couple of therioes.....

    1) Fuel mix that the boat was supplied with is wrong, the new plugs are black with oil suggesting to much oil in the mix.

    2011-12-03 19.22.33.jpg

    2) I found a linkage loose on the carby can you tell what or where this goes?

    2011-12-03 19.17.34.jpg

    I was looking at this - and it seems to be wrong compared to what's in the book there doesn't seem to be anywhere for it to connect to?

    3) Accelartor cable seems loose.

    4) Here is a video of the motor idling....

    http://www.youtube.com/watch?v=tPexX_GuL90

    So from all this I am thinking the following

    1) Fuel that was pre mixed when I bought the boat is wrong mix type to much oil. I am going to drain the tank, the carby and replace the plugs again. Refil the tank with 50:1 and plug it back in.

    2) Find out what the carby link is and why its missing?

    3) Get the marine mechanic out and get him to tune it and service it and repair speedo cable.

    Thoughts?

    Re: Ignition Circuit

    Carby link is the top carb choke should be conected via the bottom carb to that solenoid electric choke looks like only one choke linkage conected.

    Plugs look about right wet and black!

    That little lever with the thumb tab is the manual choke.

    But you should be able to choke the carby via pushing the ignition key in that will move the solenoid and choke both carbys for 10 seconds.
