Re: Runs like choked all the time


I installed a dynatehc cdi, it sparks during the kick. Oem cdi sparks after the kick is done,  like .25 or .5 seconds after the kick is finished.  Oem spark is louder and shaper, but it won't start on this cdi.



Do I need to advance the timing and run the oem box?

I have had a lot of problems with the Dyna tech CDI boxes.  They typically act like the main jet is too rich.  I have also had a few OEM CDI boxes act real rich and will kick back real hard when kick starting.  The Honda CDI boxes that kick back real hard have a timing curve malfunction and have the ignition firing around 45 to 50 deg before TDC.

Have you removed the ignition flywheel and checked for a sheared flywheel wood riff key?

You should not need to advance the timing if the wood riff key and OEM CDI box are good.

Re: TM DesignWorks Exhaust Collar I have one just like that I got in a parts lot but I never used it until recently. I used it as a spacer to pull a crank in & it worked awesome for that.

Re: Looking for a piston Good luck finding pistons.  I have a lot of engines and cylinders in my shop that have had pistons on order for over 6 months.  I need the pistons before I can bore them and get them put together.

 Don't blame me I voted for Trump. :)

Re: Ignition problem/bad cdi
Everything checks out per the manual, the source coil is a little higher than specified but according to electrosport it’s good, they also had me check peak ac output which is good at 30+ vac. I got Ricks to send a cdi since it came with one of theirs  my buddy had that was new and did not run correctly but the second one is a lot worse…..going to go ice my ankle now, never even got it to start. Who’s got a used OEM cdi for sale? The used cr ignitions I’m seeing are not even a option at this point, too much $.

Step one

Using a peak voltage tester:
Back probe the wire from the CDI box when it is connected to the terminal on the ignition coil .  It should be at least 100 volts.  If you are getting at least 100 volts peak at this terminal, the stator source coil and the stator pulser are working fine and the spark making portion of the CDI box is working.  The ignition coil, or the spark plug wire or spark plug cap, or the spark plug is bad if you are not getting spark.

Step two

If you are not getting at least 100 volts peak at the terminal on the ignition coil that is connected to the CDI box, disconnect the stator from the wiring harness and check the stator output.  Peak voltage on the stator source coil should be at least 100 volts and peak voltage from the pulser should be at least 1 volt.  The lighting ac coil has nothing to do with making spark.

Step three

If you are getting 100 plus volts from the source coil and over 1 volt from the pulser the CDI box is bad.

The above 3 step test works on any of the magneto/CDI type ignitions that I have ever tested that have a stator source coil, pulser, CDI box and ignition coil.   With this 3 step process you never need to check or need to know the ohm specifications on any of the ignition components on any brand of CDI/magneto ignition. 

If you are getting spark to the spark plug but it wants to kick back abnormally, the timing circuit in the CDI box is bad or you have a sheared wood-riff key.  The Honda CDI boxes on the 250Rs are bad about the timing circuit going bad.  If this timing circuit is bad it will usually have the timing advanced to around 45 to 60 deg BTDC at cranking RPM.
