Spree dies when given gas.

My 84 Spree starts and idles fine. When I give it gas it boggs out and stalls. I just put on new gas lines and petcock. Fuel flow seems fine. I don't see any cracks in the air box. Any ideas. Thanks

Main jet clogged? How is the air filter element? The air filter element needs to be in good shape and properly oiled. Check the air hose going to the Carb maybe there is a crack somewhere. What you are describing is classic spree issue of too much air. Also make sure the vacuum line and fuel lines are going to the right places. The vacuum line goes to bottom of the petcock and to the intake tube.

Thanks Pat. I think there was and air leak. It also could have been the main jet. I eliminated both issues. It runs great now.
I have a new problem now. The front end is shaking and knocking really bad on take off but it smooths out really quick after I get going over 5-8 miles an hour then it runs and steers great. It only does it on take off. I looked at the front end and everything seems to be tight. What do you think would cause this? Thanks again.

Wow that has me a little stumped. If it were me I'd pull the front axle and pull the wheel off aand have a good look at the condition of the brakes, bearings and the the like, it won't take too much work. And I would do it asap. It would be terrible to have the front wheel lock up on you. I'm sure the rest of the members will be able to offer some more ideas as well.
