Good to see you, John. How is business?
Here is one thing I have confirmed, main jet sizes stamped on the jets, can NOT be trusted. They must be measured to properly tune. Here are a couple examples of what I discovered.
1.. Two main jets from the sealed carbs, one stamped 76 and the other 84, measured as .032". How can that be?
2.. Cleaning jets by spraying cleaner through them, then blowing them out is NOT good enough, deposits still remain in the jets which restrict fuel delivery and atomization. Performance problems will remain with partially clogged jets.
As you know some BBK suppliers send out main jets with the 100 BBK, most send out a jet stamped 90 or 95. With the numbers being misleading at best, how much harm is the buyer causing to their new upgrade from either a too rich or too lean of a setup WITHOUT measuring and custom tuning?
I am writing a report, but I have a dilemma. Should I make it available to anyone or to tuners / repair shops only?
