Chevy TBI injector spray
Chevy TBI injector spray
(OP)
I believe I am have problems with the injectors in my Chevy TBI on a 5.7L.
It is very hard to see the spray pattern by just shining a light at the injector.
I was woundering if I could use my timing light to see the spray pattern?
Any hints on how to do so if it is a useful technique.
One thing I did notice was the the sides of the port and butterfly were wet to the point of running.
Is that normal?

RE: Chevy TBI injector spray
You need a timing light with an advance control and to see the second injector you need to put the pick up lead on another wire other than #1.
So now another question, does anyone know of a site that has photos of good and bad spray patterns?

This site has some practical information.
