definatly, you would need to buy a whole top end kit, low compression usually causes this kind of hard starting, but in the same place, air leaks can cause the same thing, but do a compression test, if the compression is good then it must have an air leak, because if you said it runs beast, then jetting must not be bad, could be just a bad air leak, i have an air leak on mine, and it cause it to start pretty hard in like 4 kicks, but the compression is good
