[Mr. Potato Head]

I'm still trying to get my Webers adjusted after only one year of shooting in the dark. If anyone's running Webers out there I'd sure appreciate a little info. The engine is running very rich with minimal backfiring. There’s a noticeable hesitation between the idle and primary circuits. If I hold the throttle at 2700-3000, the transition point, the engine stumbles and burbles. Anywhere in the RPM range at full throttle, no problem, hold on, typical Webers they always run great wide open.

Here's what I'm running under the Webers:
289/347 stroker
10 to 1 compression
Dart Heads
2.02 intake 1.60 Exhaust
1.6 Rocker ratio

Cam; Isky 279/280-1
Intake duration 270
Open 27
Close 63
Exhaust duration 270
Open 63
Close 27
Intake lift 470
Exhaust lift 470
Lobe center 108
Overlap 54
Cam advance 0
Timing 20

On top:
4 weber 48 IDAs
Chokes 37mm
Idle Jet holders 55F10
Idle air jets 60
Main jets 170
Pump jets 40
Emulsion tubes F5
Air correctors 155
3 progression holes drilled

If anyone can suggest a few changes or give me there set up I’s sur appreciate it!


Thanks,
