Raise more preflop;make it $1.50-$2 to go.

Flop bet more;make it $3.50 to $3.75 to go.If you really feel good make it $4.

Turn is either raise or push-how much does villain have left?In fact I may push this.If this were a rock or solid player I would be cautious but vs a clown he could easily be trying to price himself into a draw or who knows backdoor flush draw.

River is tough-either he trapped you with the wheel/boat or he trully did push a missed draw.If he had two pair on the flop(presuming he didn't fill up) you win.If he has a donk pair you win.
