CYCLONE 440 STARTING ISSUE.
CYCLONE 440 STARTING ISSUE.
Hi I have just purchase a john deere cyclone 440. It has been sitting 5 years i was told.I brought the beauty home and cleaned the tank,carb and installed new fuel lines.The fuel pump is pumping fuel as it should.I have pulled and pulled and pulledanyhow not i have a bad back due to pulling.I have inline spark testers and i do have spark sometimes and sometime it will not spark. It did start after pulling many times and ran OK but sounds like one cylinder untill the RPMs pick up then really sounds good.I did notice the CDI box has a large crack across the front of it.One of my qs is since this has started for a short while does this mean the CDI is still good? And i am looking for which wires to test to check ohms? ANY INFO IS REALLY APPRECIATED....
Re: CYCLONE 440 STARTING ISSUE.
When the machine starts and the RPMs pickup the spark gets alot hotter on my testers.Thanks

Re: CYCLONE 440 STARTING ISSUE.
Are you using new plugs? Did you also change the fuel line in the tank? & install a new fuel filter? Does this engine have plastic spark plug caps or rubber ones? IF plastic they could be bad??
Ck the compression, both sides should be within 5-10lbs of each other, when cking compression hold the throttle wide open while cranking.
instead of pulling & pulling & pulling to get it to fire with the choke on, just spray some carb cleaner into the carb this should make it fire, I wouldn't suggest starting fluid, a little gas will do good also.
Make sure you don't have a bunch of raw fuel in the crankcase ( with the Ign. OFF & the plugs out, pull it over & see if raw fuel flies out of the plug hole )
If the compression is low you might put a little 2-stroke oil down the plug hole to up the compression, ( it could have a stuck ring or rings from setting so long ) IF this is what the problem is & If you can get it running for a period of time on both cyl's it MIGHT break loose??
Good luck & keep us posted

Re: CYCLONE 440 STARTING ISSUE.
I have new plugs installed. and when i put fuel into plug holes or into the carb manually i did not get a result like i have in the past when they fire up and run out of fuel.When i did have it running from pulling i kept it runnin for 5 min or so .So i think the fuel system is working as it should.Thanks.

Re: CYCLONE 440 STARTING ISSUE.
It sounds that way, If you haven't already done so, ck the compression & see where that is it should be over 100, 125 + would be better.. I added a few more things to my post below while you were answering it..
I'll be gone for a few days but someone will help you work through this.. it sounds as if you have a handle on it, just keep plugging away you'll get it..

Re: CYCLONE 440 STARTING ISSUE.
You may have a CDI box issue, stator issue, or both.
I may be a bit over sensitive to this as I have found the Prestolite ignition systems on my sleds to be uniformly junk.
From your description of it running once you get it spooled up, I'm leaning towards bad stator.
If your CDI box is cracked, I'd be thinking that needs replacing too.
The good news is that both items can be bought after market from a guy I believe to be a reputable businessman. HewTech Electronics. I believe we have a link for them in that topic on the index page.
Or, you can buy used ones until you find one that works.
The procedure for testing your stator is in the FAQ section.

Re: CYCLONE 440 STARTING ISSUE.
I will see what i can find there Thanks
Re: CYCLONE 440 STARTING ISSUE.
These CDI boxes are often found rotting away or cracked. My thinking is that it is bad or intermitant.
But stators are also a common problem with the design. You can check that with an ohm meter as Brian mentioned from the info in FAQ.

Re: CYCLONE 440 STARTING ISSUE.
Today i cleaned the connections and the ground to the cracked cdi box while im waiting for a new one in the mail and i got it to run for 15 min before i shut it off.It restarts up as of now but i will give it the real test once it sits for a while and try it again.Maybe it was just ground connections or possibly the about ready wire to break that goes to the key switch from the cdi box.I will update once i know more..Meanwhile thanks for all the help to everyone.This site is like a john deere bible..THANKS
Re: CYCLONE 440 STARTING ISSUE.
OK The sled will not RE-START after cooled off...If i pull 50 times then it will fire up and run.

Re: CYCLONE 440 STARTING ISSUE.
You could have multiple problems. Check out the CDI diagnostics from the FAQ section to rule out the stator, although I have seen stator readings change for the worse when they warm up.oliver88 wrote:OK The sled will not RE-START after cooled off...If i pull 50 times then it will fire up and run.

Re: CYCLONE 440 STARTING ISSUE.
I agree with that.
When the stator cools of it falls out of spec causing a loss of spark on the low speed winding.

Re: CYCLONE 440 STARTING ISSUE.
Could it still be the stator when it does not start and i still have spark on both cylinders on my inline testers???Thanks
Re: CYCLONE 440 STARTING ISSUE.
So you do have a few different problems than.
If you have consistant spark and it will not fire than you have a compression, timing or fuel problem.
Is there fuel getting to the cylinders? plugs wet or dry?
Did you test compression? Usually 110 or better is good.
As for timing it can still be a stator/CDI issue.

Re: CYCLONE 440 STARTING ISSUE.
I just tested the compression and i have 100 lbs in both cylinders.The plugs are wet and the spark is there except once in a while it will have no spark.I will be ordering the new correct cdi box and hope that will get me closer to the trails..
