Hey all,
My Bronco sits too long as I have 9 cars I routinely work on and try to drive. I have a 670 Truck Avenger on my 74 with a 302.
When I started it up it would idle and rev up but then want to die while parked. I think I figured out the problem.
The Truck Avenger has two check balls in each metering block to prevent flooding at high inclines. When the carb sits too long and with today's terrible gas, these stick closed shutting off the main and secondary jets. To confirm this, I pulled the metering blocks off and shook them. You should hear the balls rattling around. Both the primary and secondary metering blocks had no rattling.
I simply pulled out the jets and shot carb spray through the passages until it finally sprayed through to the venturi port on the other side. Be sure both shoot through OK. Now they rattle.
Just something you all may already be aware of but if not, hope this helps if you are having problems.![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
