" The port engine in my 350 Ca
" The port engine in my 350 Catalina (Chris Craft 350Q) fails to operate reliably. I have rebuilt the Carter Carb, check the compression in the engine and it is fine. I investigated the Mallory distributor, which was changed over to electronic ignition vice points, and the voltage and resistance measurements are ok. I found the flyweights in the distributor sticky, lubricated and exercised the flyweights. The fuel pump failed and I put in an electric fuel pump. Replaced the spark plugs, checked the firing order, replaced the distributor cap and rotor. The coil was checked also. After all the above the engine runs and comes up to full power (3800 rpm), however after a few hours of operation the engine fails to idle and stalls out and is difficult to start or will not start until the engine has cooled down (the engine floods out). While operating I have a gas smell emitting from the exhaust. This leads me to believe the engine is running rich. Am considering replacing the old Carter Carbs with new carbs. Any recommendation as to make and model and what size carb to get? Is there anything else I should check on the engine? Also, I am unable to find timing marks to set the ignition timing, need help here. "
