Check the starter too.. IMOHO that starter always cranked real slow but the car always started so i left it all in. I honestly don't remember what jets are in it and if there is a power valve or not ( i don't run power valves) YES i always smelled the exhaust and some fuel... I'm immune to it ..AND YES IT SHOULD BE TUNED FOR YOUR CONDITIONS
YOU ARE MORE THEN WELCOME TO CALL ME ANYTIME (YOU'RE NOT BUGGING ME)

AND IF I CAN AND I CAN REMEMBER,, I WILL HELP YOU
