RPM- Iddle issues
1970 C10 p/u 350 5.7L with a performance cam, edelbrock 600cfm carb, Timing set at 12 BTDC.
My issues is this: In park idle is runs about 900 rpms. I let it warm up to optimal operating temp and once I shift to reverse the rpms dramatically drop to 300 or so for a bit before it comes up to 500. Once I get going it runs well. BUT when I come to a stop light the RPMs drop to about 300 and the truck sounds like it wants to stall before it kicks itself back up to 500 rpms. I have checked timing, vacuum leaks, accelerator pump, jets, springs, spark plugs/wires and so on. I am at a loss as to what I need to do next. PLEASE someone help. ![]() ![]() ![]() ![]() ![]() ![]() |
