I have an SLT 700 and it has no spark. I need to know where to start. I am new to PWC's but been in small engine repair for years. I just need to know where to start..I am helping out a buddy so I want to keep all cost's down. I would like to also say that we had the engine running before, then he swapped it into another PWC adn now it wont run. I really have no experience with CDI's so all help is much appreciated..
