I think I may need a Easy pull, I have a 07 400ex and when she dies for whatever reason when its hot. You go to try to start it again and compression kicks back at the starter.

Mods is Stage III Cam,Slip on, Big Gun Rev Box. Roughly how much are they also

Why would you use a stage 3 cam on a totally stock engine?

Unless you got motor mods use a stage 1 cam, it makes no sense to use such a high performance cam in a stock engine and its probably whats causing your starting issue.

with that stage 3 you hardly have 6:1 dynamic compression ratio. probably less than that. i would venture to say that that is hardly enough compression to even keep it running when idling let alone when it is hot. if you just did all of this, i would say that it is a jetting issue of being lean on your pilot (which is probably the case even if it was done earlier this summer) but it is really hard to say. you could try to go out on your f/a a half turn and see if it gets any better, if not turn it back. other than that, get a different cam and try again or pump your compression up to 11:1 or 12.5:1 imo i am interested to see how this plays out. steve
