wont idle and exsecive smoke

[roaddog]

Ok, here's what I have. I have an 87 Spree that i just picked up that would not run.
It had low compression, so i installed a new top end kit.
I got it to start, but it would not run correctly.
I found it had an aftermarket carb on it.
I got an OEM carb did a complete cleaning, all ports verified with light shining through.
Then I put carb back on and can't get it to idle and will not rev very high until i take the air box top off.
With filter installed, it will rev with good throttle response, but smoking heavily.

The first thing I do with every old scooter I get is delete the oil pump and pre-mix fuel 32:1. Its a great system when they work but a nightmare when they dont. This may not be your issue but it eliminates the possibility and stops future headaches. With pre-mix, you KNOW what the mixture is. The pump is always a blind guess.

tried having oil pump deleted and run mixed fuel with no change, runs ok on start up then when bystarter closes runs like crap until i take the top off the air box then it will rev and run ok.
thanks for any help
