Hard starting

    My 1995 Daihatsu Hijet s80 547cc has always started bad but now that it's winter its even worst and I cant figure out what's wrong.
    If I manually choke it's a little better but not very good and I adjusted the valves and changed the fuel filter, air filter, sparkplugs.
    Any ideas?

    are you pumping the gas pedal 2x before trying to start ? is the starter turning noticeably slower than in summer? if so than you may need a better battery..slow cranking creates less vacuum and therefore pulls less fuel into the engine to start it..is your accelerator pump actually squirting fuel into the carb ?

    Yeah it doesn't seem to do anything. I haven't noticed a difference with the starter. I can't tell if it squirts gas or not.

    And it shakes a lot when it starts.

    sounds like improper ignition...when it is started and idling poorly pull the plug wires one at a time till you find the cylinder responsible..what plugs did you use ? also try grounding the distributer to the battery negative post with a set of jumper cables...you are getting poor spark or have a bad plug I think

    I pulled the distributor cap and its really bad looking. Are the s83 caps the same I can't find any s80 caps there's one on eBay but its says it for one with points only.

    Thanks Jim, But I ordered the cap,rotor and sparkplugs for $60 shipped from G&R Imports.
    Ill let you know what happens after I change it.

    I got the cap and rotor and put them on.
    Went to change the spark plugs and got two done and pulled the third and now can't get it to thread in.

    OOh be careful it's not cross threaded...how did the plugs that came out look ?

    Fine. But it threads in then stops and I'm not about to use the rachet in case its not right.

    You can find special spark plug taps or chasers to clear out the threads. I think sears sells them. Anyone know what size the threads are?

    Thanks I got a thread chaser and I got the spark plug in.

    So how does it run?
     
  15. chaseoe

    I'm not sure. I prolly sound stupid but the cap goes on both ways and g&r doesn't know which way it goes.

    Ha, ha, ha...
    Not stupid at all chaseoe. Sometimes you don't give yourself enough credit.

    You have just uncovered the reason why we see posts like... "just did a tune-up, but now it won't start".
    BUT, they never "own-up" to the simplicity-of-it-all; after a few days of messing around, they usually just post "figured it out"...;)

    Just put it on the one way, if it don't fire right up; switch it around.
    If you messed with the adjustment, just put it back to where you think it was before, try both ways...then adjust...

    Not a problem with a 4 banger...:pop:

    Ok it will only run one way?
     
  18. spaner

    The timing will only be "in-alignment", ONE way.

    You could "set-it" for the OTHER way, but that would almost certainly include a rotor-gear "re-mesh" adjustment.
    Some guys may have even been able to get it to start and run, "the-wrong-way"; but it would run like crap...not enough slider adjustment.

    None of that really maters to you though. Your timing was already set. You just need the cap on the right way.

    I sent it to your e mail addy. The chat isn't working for me now

    Ok thanks. I haven't even tried starting it or adjusted it so ill try it tomorrow when its not dark.

    Keep in mind that it "could" be set either way.
    The chance that yours is the same way as Jims'...50/50...;)

    Well it starts and runs but it didn't make a difference changing them really.
     
  23. spaner

    spaner Well-Known Member

    If it runs, then you've got it the right way.
     
  24. chaseoe

    chaseoe Member

    Yeah but it didn't help with the hard starting.

    Then, it's not the issue.

    Here, so everyone can see what we've been talking about; with a "THREE" lead cap.

    and it runs fine after it starts and warms up.
    So I don't know why it starts so bad

    Probly a leaky carb.

    Try holding the choke open with your finger right on the choke butter fly, crank-it...

    If it fires-right-up...then dies...(no matter what) that's what it is.
     
  28. chaseoe

    It just cranks and cranks and then fires and dies .

    Then, try a hair dryer at full speed and heat, right at the carb.
    Keep it there, after it fires...

    You means to warm it up?
