Well-known member
I kindly ask for your advice/help in either setting up my Weber 38 or find a new carburetor that will better suit my application.
As everyone else, I'm trying to get the most out of my car.
This is my current setup....
- 67 mustang with a 200 .030 over and block height is .010
- Clifford 272 cam advanced 6*.
- Vintage inline Aluminum Head, no porting performed, Freshly installed this past month
- Weber 38 DGES carb - 50 Idle jet, 160 Main Jet, 210 Air correction jet. Idle speed 3/4 turns in (verified visually that the transition holes are not exposed and no vacuum at 830 RPM idle) idle air mixture screws out 1.65 turns each
- Tremec 5 speed manual transmission 9" organic clutch
- DSII Distributor recurved locally- Initial timing 22*, Mechanical advance 20* with total approximately 41-42* without vacuum advance. All in at 2550 RPM. I plan on purchasing a new distributor from Bill in the near future that will have a better curve.
- MSD 6AL2 Ignition Module
- 1.65 Yellar Terra roller rockers,
- clifford dual header and exhaust
- Rear end is 3.20
The car runs great at idle and above 2000 RPM pulls hard.
The issue is the car fall on its face at WOT from 0 MPH or anytime i go WOT below 1500 RPM. Not sure if its a cam issue, timing or jetting.
any help is greatly appreciated.
