Weber 40 DCOE

After setting the ignition timing with a strobe ( finding out I was only out by about 5 degrees retarded by guesswork. ) Without driving, I could tell that throttle response was sharper and the engine just sounded better.

Then I remembered that I had never cleaned the fuel filter elements in the carbs, so took them both out (quite a lot of crap near the top part of the screens). Didn't drive it till today, started out by being hesitant on acceleration and generally missing irregularly under throttle.

After 20 miles or so get back home and it's even worse now, spluttering, popping, terrible.

Switch off engine, remove bonnet and clearly see fuel pissing out of both trumpets of the front carb.

Sticking float? blocked jet somewhere? Any procedure for this anyone?

PS it's a Lotus twin Cam.

Thanks.

OK Chaps, thanks, job done. Seems that when I pulled the filters some st must have been dislodged and got into the needle valve.

Tops off, needles out, good wash and puff of air, sorted.

Thanks.
