As for the emission test, 1. Do you observe any oil burning ie blue smoke from exhaust when engine is fully warmed up. 2. How about the condition of plugs and air cleaner? Are they reasonably new? 3. Before any clean up/tune up done on the carb check if the PCV breather line (located below the air cleaner spout ) i not clogged up with all carbon gunk. 4. With the air cleaner cover removed check if fuel is atomized properly inside the carb barrel when the engine is revved up. If it comes in large droplets then most probably the emulsifying tubes are clogged up and could be the reason for rich air/fuel mixture. BTW nice to see someone with a passion for Lancers.

what was your last car,is this your first 660cc Kei-car? These engines are continuosly working at the high end of the possible performance curve and not designed to last until 300,0000kms like the 1.5L Corollas. I would think of it as a disposible item.

#3. PCV in this case is a thin tubing unlike the valve you find in newer engines. If left unattended before doing a carb tune up, a clogged PCV will result in a wrong throttle position setting at idle. Why I mentioned this is because most of our mechanics do not bother about it. However, this tube can get clogged up from cam cover end. Best method to check without opening up the cam cover is to fix a tight fitting plastic tube to PCV tube and blow with your mouth. In case if you happen to open the cam cover for any other reason make sure that you clean the oil baffles inside the cam cover together with the tube. Edit: Discussion on a similar thing.

That engine bay actually looks much better than the previous car. It even has the ducting for the air filter which is missing in most cars. Share more photos. We promise not to say anything that will hurt your feelings. Looks like significant improvement after the distributor contact breaker and high tension leads replaced. However as Rumesh has mentioned, the high CO indicates that the engine is running rich. So double check your air filter and PCV. My opinion is that if you must overhaul the carburettor, then just use a carburettor repair kit and get an expert to do it. I have had nightmares with makabases experimenting with my carb and I even had to swap it out because the first carb was messed up too badly to restore.

Replace the spark plugs and airfilter3 TT
