Hi, thought I might get some good trouble shooting advice on this one. My 2084 is starting hard now. When I try starting it spins over fine but won't start. If I jump it to get the extra starting power, it spins over very fast and will start. Just to be clear, the battery is good and spins it over more than fast enough, but for some reason it seems to need the really fast turnover to catch.

I have spark, I have fuel, replaced the fuel pump recently. Choke butterfly is opening and closing fully.

Once running, it runs smooth at half throttle, but at higher throttle settings it coughs and sputters a bit. It doesn't die, just seems to miss at times.

I'm wondering if I have a weak ignition, like I said I have spark but maybe it's not strong enough? Curious to hear some thoughts on this.
