Answer 1

i don't know much

but i know my car did something like that for a little bit..

it could be a vacuum seal or a dirty oil filter...

Answer 2

could be an electronic thermal valve problem. Thats the component on your carb with the 2 wires comming off it. Should get warm/hot to the touch after running for a couple of minutes. Warm/hot means good, working..if not, you could be dumping in too much fuel.

OR,.... check 4 airleak @ intake manafold. spray soapy water on intake seal and check for suction.

good luck
