has park but wont start
 

I recently traded a jet ski for 2 buggys 1 runs fine but has some clutch issues and the other has spark but will not start witch leads me to believe the timing has jumped or the woodruff key has sheered off' but I can find nothing on how to fix it and im having a hard time finding the prts i my need i do not want to just tear into the motor with nothing to go by. Please help any and all info would be greatly appreciated.

Both of the buggies are water cooled 250's I don't know what brand they are. 1 uses a dual chain drive with independent rear suspension and the other uses cv axles and independent suspension as well. Thanks again for any help.

Nobody has anything? Am I right in thinking the timing has jumped or its a sheered woodruff key? I have no experience with these karts and I do not know anyone that has one.

step by step
 

First off welcome to the forum u have come to the right place. Could u possibly post some pictures of the buggy's so that we can try to identify what ur working with? u dont want to start off with the wrong info & we dont want to give the wrong info. Second u need to contact Mr. Tom Syc @ sycpowersports his header is at the top of the page, he is all things buggy, he can get u the info u need on parts, repairs, & research, plus u get a really sweet discount on the part that u order from him for being a member of this forum! Last when asking for assistance please be patient lots of us on here dont really get into the forum til the weekend due to our family & life commitments, but trust me were are glad u have joined us in luvin these little buggy's!:drive:

as for the buggy with spark, check ur valve clearances to make sure theyre right & then ur carb!

Post pictures. I think the dual chain model is a GK13 and the other is a GK06. They are made by Goka but sold as Roketa. Both engines are CN250 with different final transmissions. The basic engine was used in the Honda Helix scooter.

These are the buggies the newer looking red one is the one that wont start.
Thanks for the welcome and helping me guys.

The red buggy has a vin plate that says SQ-GKB I can find no plate on the other 1.

Check the master cylinder. Make sure it is filled with brake fluid. Check the kill switch (if so equipped) and make sure the petcock (again if so equipped) is on and allowing fuel into the carb. Check the fuel tank to see if there is fresh fuel in it. Try starting fluid. If the timing has jumped as you suspect you have 2 alternatives...Rebuild the existing engine or purchase a new one. Look for a number stamped onto the engine. Do a search for it on line...you may get lucky.
