I see in a previous thread you were having problems with the mixture adjustment on the cis. Have you removed any spark plugs to see how they look? They can give some insight into how it is running. They could be black from oil burning or rich mixture, tan to off white for clean burning, or white from too lean. If they are wet with gas then the ignition could be the issue. Has the smoke out of the exhaust looked black, blue, or white? Has the car backfired? Is there a pop off valve in the air intake?
