Help needed diagnosing Weber 40 IDA 3C problem
Hi Folks -
FWIW, except for Weber carbs, ported heads and cams with more aggressive acceleration ramps, the engine in my 914/6 is essentially built to ‘73 Carerra RS specs.
The engine ran fine, but suddenly began missing under operating conditions less than approximately 75% throttle. However it still pulls smoothly and strongly at WOT to redline.
Checked the idle jets. All are clear.
Driven only 369 miles since PPI and extensive servicing, including carb sync and idle & mixture adjustment by preeminent Porsche shop.
What should I check next? (Beside checking and possibly upgrading fuel & air filtration already on my radar)
Any help greatly appreciated.
