Hobbit 70 kit with vm20 carb and points ignition with cranks pipe. Idle jet is 17.5, main jet is 160 now. Tried 180 as well. Can't get it to idle or run worth a shit. Choked or not. Suggestions?

Your jetting sounds good enough to idle. I honestly never had to really change the idle jet on the VM20's I've run.
Sounds like you may have an airleak somewhere.
Did you rebuild your bottom end? Probably a bad seal
I did rebuild bottom end with new bearings and seals
Every vm20 I've bought has had a 22.5 idle jet, and that has worked just fine.
