Smoke testers are real nice for finding vacuum and vapor line leaks.

Hi, don't you test for intake leaks with spray carb cleaner ?
that's the common way to find intake leaks on a running engine.
  Or listen with a listening hose, that's very effective too.

I have found as many as 8 to 10 tiny air intake leaks from TB, to plenum, to
intake runner boots, to the the heads.

one MUST chase down any and all intake leaks, no matter how small, if they
want the engine to do everything right.
