I Just ordered a new CDI. Have you checked your flywheel key? If so, I'll let you know if the CDI fixes it. In the meantime, remove yours, shake it, and blow into the connector. I got mine to start and run for a minute by doing this. Obviously it's not a permanent fix lolTenacious T wrote:BMX - I hope you find the problem soon because I picked up a1985 Spree with the exact same problems !!!! So here is a Question for the experts ? I can see a mark on the flywheel and when it lines up with a ridge on the case - that's top dead center . If you have the spark plug out - hooked to the coil - grounded - key on - rotate the fly counter clockwise will you see a spark jump the gap when you pas TDC. ???? If you can I'm thinking coil or cdi. So when a cdi goes is all or still some spark ? I have done everythin BMX has done and I'm at the same spot !

It's easier to stop caring three years ago than it is to fix it in present time.

Spark is rarely if ever at TDC, almost always BTDC.Tenacious T wrote:BMX - I hope you find the problem soon because I picked up a1985 Spree with the exact same problems !!!!

Re: 1985 Spree... Timing issue?
I removed the flywheel last week and the key was fine. I ordered a CDI.Trafficjamz wrote:flywheel keys almost never fail, if the flywheel has never been removed.
Get the proper tool to remove the flywheel, or else you will most likely damage the stator or the crank.

Definitely NOT a starter issue,
why would a bent flywheel key make it stumble like that?
And why would having the kill switch on or off make a difference?
This is a two stroke , so valves are not opening or closing.
why would this not be a starter issue?
A bad ground to the starter would make it stumble
The kill switch being on could be making a better path to ground.
There is no way this is a starter issue.

And why would having the kill switch on or off make a difference? No spark, no kick back.
This is a two stroke , so valves are not opening or closing.
why would this not be a starter issue? Because with the ignition off it does not do it.
A bad ground to the starter would make it stumble No, electricity does not work that way.
The kill switch being on could be making a better path to ground. The kill switch goes only to the CDI and is totally separate from the starting circuit.
There is no way this is a starter issue.

Re: 1985 Spree... Timing issue?
Back in the 70's ( yes I'm old ) I had a 360 Husqvarna ( the one with the big bolt sticking up by your jewels ), left side kick start with a lot of compression . One day I started it -it backfired and quit ! Kicked it again and started right up , put it in gear let the clutch out and what the *, I'm going BACKWARDS !!! What happened is when it backfired it sheared the key and the fly moved on the crank ! By the way 2-strokes run as good backwards as frontwards . Thats the way old boat motors had reverse > you would shut the motor off move a lever changing the timing start it back up and you were in reverse !

Re: 1985 Spree... Timing issue?
Superbee : Thats good news because I went ahead and ordered one from the same place as you . It just came in the mail today . Bad news is my Spree is 50 mi. away and I'm not going back till later next week. If the new CDI and coil fixes mine they will have to do a new chapter in Wikspreedia !

Re: 1985 Spree... Timing issue?
So - I replaced the CDI and coil and had no luck . What next the stator ? The new CDI has a LED that should light every time it fires . No light but still has a weak spark . Has anyone else ever had to replace a stator ?

Re: 1985 Spree... Timing issue?
Okay. Maybe your flywheel magnet has gotten weak. Stick something to it and make sure it's not super easy to pull off. Check your magnet pickup and make sure it's not bent. Your plug should be gapped at .24-.28 if I remember the manual correctly. I have mine set at .25. I don't remember if I asked you, did you pull the flywheel and check the key?Tenacious T wrote:So - I replaced the CDI and coil and had no luck . What next the stator ?

Re: 1985 Spree... Timing issue?
Spending money and throwing parts at the engine may well fix it sometime in the future, but a little troubleshooting will confirm what is bad and what is not and fix it with one purchase of parts. But it is your time and money, do it however you want.Tenacious T wrote:So - I replaced the CDI and coil and had no luck . What next the stator ?
