Again, just for the record, I've never denigrated the 22-cent mod, or even swapping OEM needles for replacements of proven merit.
The 22-cent mod raises the needle; so does an O-ring kluge. A different needle profile alters air-fuel mixture, as doubtless does grinding a needle by hand on a bench grinder. Now . . . where lies the innovation/discovery following these well-worn paths (influence mixture by raising needle/changing needle profile)?
By all means, try the modification under discussion, and report (with, one hopes, repeatable, quantifiable testing methods and data) your results. BTW, incidentally, the cam advance plays to decidedly MIXED reviews. Quantifiable maintenance consequences of the Thermo-Bob remain elusive (although the device performs as advertised, enhances coolant temperature stabilization and at a higher nominal operating temperature).
Innovators, thinking "outside the box," have brought forth useful discoveries. Re-inventing the wheel (as in, raising/re-profiing the needle) isn't one of them.
Then again, COLD FUSION was once "discovered" in Utah. Unfortunately, however, the phenomenon (cold fusion) has never been detected beyond Utah's borders!
