ok this whats going on I have a hot cam stage 2 , fcr 39mm carb, 416 ss kit with 11.1 , curtis sparks xr 6 pipe, sparks rev cdi box. Its hard to start if the battery is not fully charge. ok I thought its the cdi box. but heres what happens after about 30 min of throwing the hammer down on the beast. its really hard to start it takes about 5 to 7 times hitting the start button to get it going but its unbelievable awsome when its running. any help would be appreciative........::confused:

I was told that with out the decompression valve that it would be hard to start any one with the same problem.....

I would have the battery tested.Probably bad.You don't need decompressor with that cam because the long duration bleeds off compression at low rpm's.That's why you put in high comp. piston so you don't loose so much bottom end power.
