Im having timing issues after trying to put a 93 700 motor into a 99 700 chassis. The only significant thing I changed on the 93 engine was the stator and stator plate as the 93 motor was efi and the 99 is carbed. I put the 99 stator and plate on the 93 but used the 93 flywheel. Ok well after getting it in and firing it up, it will only idle and will not do anything more than an idle without backfiring through the carbs. After talking to a guy about it, he asked if the magnets for the timing pickup were in the same location on the 93 flywheel as the 99. I looked and besides the 99 flywheel magnets being longer, they arent in the same place. would this throw off the timing? I mean the timing sensor pickup and the flywheel are stock to this motor. Does the 99 cdi expect the timing at a different time than what it is now getting? Im having a hard time wrapping my head around this. Do you think by changing the location of the magnets on the flywheel it will make the timing right for the 99 cdi? any thoughts would be cool. Also does anyone have a scan of the 93 wildcat 700 efi wiring diagram handy they can send to me? Id like to have a look at it. Much appreciated

Get a '99 flywheel- problem solved. Magnet location in relation to stator coils works in conjunction with pickup coil to deliver spark at the right time.You will beat your head against the wall and accomplish nothing by trying to move the magnets- nobody does that. No offense, just the truth.

No offense taken. The problem is the 93 crankshaft has a smaller taper than the 99 so the 99 flywheel doesnt fit. I have tried it and the 99 flywheel bottoms out on the stator and plate. Heres a pic of the two flywheels. They are perfectly aligned with the crankshaft keyway. The 99 is on top . If the stator/flywheel inner magnets have some kind of timing critical relationship, then yes, this wouldnt work. The fact is, the machine ran and headlights worked and spark is strong with the stator as it is. Just the exact time of ignition is off which is controlled by the timing sensor right? Now I know u may say" just get a 93 carbed flywheel" Thats what I thought too, except the 93 carb flywheel didnt have the magnets on the outside as the pickup was inside. So short of starting all over again, I think my only option at this point is to try the magnet moving thing or try to figure out the wiring on the 93 stator and make it work with the 99 cdi.

The problem is that the timing pick up reads the raised metal on the outside of the flywheel (in red), and since they are in such a different spot your timing is way off

To get it to work, you will have to move either that piece of metal, or have a new keyway cut so that the timing is correct. The easiest way would be to run the engine, find out what the current timing is, and what it should be, and have a new keyway cut. I dont think you can weld on the flywheel without destroying the magnets, or the glue that holds them in place.

thats a good idea.Thanks! Ill keep that in mind when i talk to a machinist here monday. Im thinking too that maybe I could get a sleeve made that will fit inside the bigger bore of the 99 flywheel to make the hole small like the 93. another possibility. What about the wiring on the stator? one 4 prong plug on the 93 stator is the exact same as the 99. The other 3 prong plug is different from the 4 prong on the 99 but i wonder if i really need all 4 wires. like if one wire is for the tps sensor or some other useless feature then maybe i could just leave it disconnected. I would need to see a wiring diagram of the 93 stator though to know. anyways, i guess ill be going with the machinist for now as i dont have the 93 wiring diagram.

As for finding out the timing, theoretically if I get the keyway cut in the 93 flywheel so that its magnets line up like the 99 flywheel, that should do the trick.

The magnets dont matter, its the metal piece on the outside of the stator.

Right! I thought all this time that the metal pieces on the outside of the flywheel were magnets
turns out they arent and that the pickup is the magnet end. I took the flywheel to a machine shop
and the keyways were too close to cut a new one so we decided to go with the sleeve.
The guy caled today and said its ready so tomorrow I will go get it, find a bit deeper
timing key and put it back together. Boy I hope this works.

Alright! Well i got the flywheel back today and the guy did an excellent job making the sleeve for the 99 flywheel. I installed it, and the sled fired up on the second pull. Runs great! did a catwalk up the street to my buddys surprise. Lol . so there you go. If you want to put a 91,92 or 93 700 engine into a 94 and up chassis,just get a machine shop to make you a sleeve so that you can use the newer flywheel and stator and your wiring will all match up from engine to chassis. Thanks for your help and suggestions guys and have a look at the pics of the sleeve installed on the flywheel.
