Carb problems

How’s it going Honda forums. I’m new to this site. I’ll start with the type of bike. I have a 99 Honda fourtrax 300 4×4. I bought the bike and it had been sitting but cranked up first start fastest than some newer bikes I’ve seen. Later found out that the gas tank was completely rusted out. So I bought a new tank and decided to clean my carb, while I was at it I went ahead and bought a jet kit to get a little better throttle response. After installing and cleaning all of my jets I but the carb back on. Let gas into the carb and tried to start it but the bike wouldn’t even start up. I noticed under my carb where you bolt on the primer bulb that it was leaking a little bit of fuel and also blowing a little bit of air I could feel on my finger. I took it off and saw the seal on the inside was torn. I ordered a whole new primer section. I wanted to make that it is the primer section or what else it could possibly be? Any ideas?
