it has spark and it cranks over but wount start

 

Check everything else an engine needs to start. Fuel would be the first thing I'd check. Then also check ur timing, ur timing belt could have jumped a tooth or two, causeing the engine to not start, If all else fails, u could do a compression test. Check to make sure the fuel pump is priming when u turn ur car to the on position but not started yet, their should be a hissing sound coming from under the hood pretty noticeable. Any cel's?... Hope this helps

 

arent those carburated?

 

Yes they are.
