A Solid TellTale Stream Without Exhaust! I had to see what the telltale project was like. This was an easy project and will have ?A Great Advantage?! I?m really sold on the solid stream w/o exhaust mixed-in or showing. The previous owner of the 55 HP cover (on this 1970, 35 HP Chrysler) probably had a telltale. After drilling the approx 5/16? hole (on the closest side) I discovered or remembered one in the ?C? in Chrysler on the opposite side. I think I have less stiffness looking to my left. LOL JOW
