Agree some with those saying "the more I read, the more confused.....".

One of my Weber books , by PatBraden, have tables of e-tubes and tuning preference.

In one table F7 is said to be lean, in another "richer low end"...

Well; I run F11 in my IDF's on the 347. If I read GAZ64's table correct, this would be rather unusable (cylinder size 250- 325 ccm). But, my engine is running well, ableit a little rich (A/F 10,5- 12,5) on RPM range from 3000- 7500.

In all tables I have senn F11 is placed in the "normal use" group.

F2 I find under "Alcohol usage".... So, very rich, then?

If someone steps up and says "You should use F..", I'd go and buy a set . If then engine runs smoother and with more correct A/F than ever, I would really appreciate & look up to this person, indeed.

Anyone wants to make some definte conclusions on E-tubes?????
