[stephenf]

ive taken 1.8L and put 96mm big bore on, balanced pistons
a newer cam better tuned for the carbs,
44idf webbers, targa exhaust
complete rebuild
removed all heater boxes and dammed the ports

I did the same thing on the same engine. Started with 44s which ended up displaying similar symptoms. Changed to a good set of rebuilt 40s. Once I got them sync'd they were fine. You'll probably still have fumes and oil all over the place. See Georges comments in the 700 tech tips for what you can expect with carbs. My fuel mileage sucked too. Worse with the 44s. If you can afford it I'd recommend you go with aftermarket FI.

Thanks for the input but i made a mistake on my posting....I HAVE 40 IDF WEBBERS NOT 44 IDF'S AS EARLIER POSTED>>>>

I CHECKED THE JETS ON THE 40'S AND THEY ARE WHAT WEBBER RECOMMENDS FOR THAT CAR.....F11 EMULSION TUBE AND 1.15 MAIN JET; I ASSUMED ALL THE OTHER JETS WERE THE STANDARD SIZES FOR THAT SET UP.....AS I DISCUSSED WITH THE SELLER BEFORE I BOUGHT THEM WHAT TO USE

THE FUEL MIX MIGHT NOT BE PERFECT BUT THE PLUGS LOOK FINE AND THERE IS NO VISIBLE EXHAUST CLOUDS OR SMOKE
ADDITIONALLY- I PULLED THE PLUGS AND THEY LOOK PERFECT....LIGHT BROWN CONDITION NO PITTING OR DEPOSITS

BUT I STILL HAVE THE SMELL......WHAT DO YOU RECOMMEND

1. TAKE TO A SHOP AND HAVE THEM RUN SMOG MACHINE TEST TO DIAL IN PERFECT FUEL AIR MIX...REMEMBER I HAVE NO SMOG EQUIPMENT ON IT?? OR

2. WHERE THE OIL BREATHER TUBE RUNS OUT OF THE TOP OF THE OIL CAP....I ROUTED IT UNDER THE CAR ON THE DRIVERS SIDE.....SHOULD I RUN IT THROUGH THE CHARCOAL CANNISTER BEFORE IT EXITS/?

3. THE CAR RUNS STRONG ( FOR A 4 CYL) AND OCCASIONALLY HAS A POP SOUND FROM CARB....LIKE WHEN 1ST STARTING OUT...BUT HAVENT NOTICED AFTER RUNNING 5 MINS.....AND MY UNDERSTNDING IS IF ANYTHING THE POP IS BECAUSE ITS TO LEAN...

4. TIMING SEEMS GOOD....NO RUN ON AND NO POPS ON FULL ACCELLERATION

IT STINKS AND I HAVE TO KEEP MY WINDOW CLOSED....
GOT IDEARS???
