Hi Guys,
since I'm slowly running out of Ideas I would like to invite you to my guessing game:
1. The Car:
77 Clubman Estate fitted with a A+ 1293 engine - big valve Head but std. Metro cooper Cam. Fitted with a Bosch Alternator, 123 Ignition and A+ Starter. Also it has a 1275GT Speedo with Tachometer. I'm running a 123 Ignition with a Bosch Blue coil, NGK Sparkplugs and "High performance Leads".
The car is running on a Single HIF44.
2. The Problem:
The car runs fine most of the time. BUT when I hit around 4.000RPM and hold it on that RPM on the Motorway it starts to stutter. The Problem dissappears on full throttle.
Also it takes a while after starting the Car, before the Tachometer starts working. Under hard axceleration the Needle wobbles around quite a bit.
3. What have I changed so far:
- Ignition Coil, switched the 123 Dizzy with a fresh Standard Lucas 91 Carb-Cooper one (65MD-something) same result.
- new HIF44 Carb with new Fuel Filter
- new Sparkplugs and Leads
- new Alternator
I'M GUESSING now something electrical?!?!
I'm happy for any suggestion
Cheers from Germany
Marc
