I have spark , it wont fire though. I don't have a compression gauge but i can use kick starter with my hand very easily. I am guessing not enough compression, so this is beyond anything I'm equipped for so I went to the dealer I bought it from he is going have a local motor sports shop see if he can help out, he has already told me he is going to work with me on the labor cost because its barely out of warranty I purchased it new in 08
