Edelbrock 1407 issue

Basics, basics.
- Did it ever run well?
- New?
- Check float level, should be 7/16"
- check for acc pump shot: engine off but carb full of fuel; operate the linkage while looking for a fuel squirt into each pri bore
- check that met rod pistons & rods are in place. When re-fitting pistons, tighten covers so that pistons are captured, but you can see them. Run engine, in gear idling, if auto. Pistons should stay DOWN. If they move, you need a softer step up spring. Move to neutral & blip the throttle, pistons should pop up & hit the covers.
- does the engine have a 'hot' cam? This could expose too much transfer slot. Refer to the Edel handbook for fixes.
