I recently bought and old Kazuma Dingo 150cc and to begin with it started just fine. Then, for no apparent reason, it wouldn't start. It turns the motor but fuel isn't getting to the spark plug.   
As mentioned in the title I've since replaced the fuel filter, the carburetor, the ignition coil and the spark plug. Fuel comes into the carburetor but seems to go no further. Is it a vacuum problem? Does anyone have a good idea about how I could diagnose the problem? And how to fix it?

I don't know what year it's from, sorry.

Sincerely
Mikael

Is this a four stroke or a two stroke ?

Have you taken the carb off and stripped it and cleaned it ?  That's first I think.

It's a four stroke.
Yes. First I tried to strip and clean the carb but it didn't help. Then I replaced the entire carb with a brand new carb. Still didn't help. So I'm wondering if maybe there's a vacuum leak between engine and carbthat prevents the carb from doing it's thing or something is stuck inside the engine so that the vacuum isn't created. But I don't know how to diagnose or fix it.

Will it try to start on starting fluid.

I haven't tried. Where should I spray it? It seems that fuel isn't getting past neither the old nor the brand new carb, so it hardly makes sense to spray it into the air filter.

You should spray the starting fluid in the air inlet of the carb or if the air filter is still attached spray it on the air filter if its sucking correctly it will get in there, if still nothing, take the air filter off and put your hand over air inlet if working correctly you should feel suction when cranking the engine on your hand and hand should get wet with gas.

Exactly what I was about to say..  put your hand over the carb's intake for a second while you crank it and feel for suction, and then see if it's getting petrol through.

      1989 Moto 4 YFM350ERW intermittent spark.
      By RGS
      1989 Moto 4 YFM350ERW intermittent spark.
      Quad has set for about 7 years and was running when parked.  When I replaced the battery and attempted to start it had no spark. 
       
      What I have done.  Followed troubleshooting in the manual. 
      1.       Coil failed the resistance check so I replaced it.  Still no spark.
      2.       I performed resistance checks on the stator and they all pass.
      3.       Found a bad rear brake stop switch and unplugged it and connected the wires in order to disable.  Now I have intermittent spark.  I believe that the issue is with either the stator or CDI and not sure which.
      1989 seems to be a transition year for electrical.  I can get new aftermarket CDI units for 87-88 and 90-94.  I cannot get ones for a 89.  I can get new stators for 87-89 and 90-95.  Looking at the schematics the wiring on my moto is closer to the 90 ones on the ATV side of the CDI and closer to the 87-88 on the stator side of the CDI.  Looking at part supply sources the stator housing is the same part # for all the years and looking at some of the stators on Amazon that have the dimensions on them both of the stators are the same size.
      What I am thinking of doing is to replace the stator and CDI with a 90-95 one as these parts are all readily available.   Does anyone know if this has been tried before and if there are any issues with doing this.  
       As a side note I also have a 1993 Moto 4 YFM350ER that has been sitting longer but it is located about 400 miles from me at this time.  By doing this change in addition to being able to get parts I will also have 2 ATV’s that are the same electrically.

      I just bought a rare beast!

      Hello All
      I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

      Hi my name is Greg and I just acquired a free 2000 yamaha kodiac 400 4x4 with the ultramatic transmission that does not run. I plan to get it going and use it around my property

      Troubleshooting a no spark issue, was running OK, maybe a little rich, turned it off, now no spark. I've checked/ohmed out the main key switch, the start/stop switch, neutral switch, brake switch - all good. It will crank the starter, but no spark with the starter or when I try the pull start. I've checked all fuses and diodes. Swapped battery. New plug. New coil. Swapped in a used CDI - no help. Traced, removed, cleaned, reattached all grounds. Removed things like my winch from the circuits to be sure a bad relay or something was dragging it down. When testing voltages, the orange wire going from the CDI to the ignition coil shows no/very low voltage-shouldn't it have 12V on it? Sometimes I get a very weak, intermittent glow on my spark tester, but not enough to fire the plug. I've checked continuity on just about all wires in the harness. Checked/cleaned/lubed w dielectric grease- all connections, redid a few that looked old/dirty. I've checked the stator resistances, all good, but have a stator and rectifier ordered anyway, will arrive Sunday. I verified that the rectifier has a voltage output back to charge the battery while cranking - 10.5-11V, low, but expected while starter is engaged. What else can I check as part of troubleshooting? I have a Haines service manual, but the 1999 350 4x4 seems to be an odd model, there isn't an exact electrical diagram for it, but found one for another year that has all the same number of wires and same color wires, so I've referenced that. Any hints, tips or advice would be appreciated! Thanks!
