Need a little help, and I have searched but not coming up with good results.
I have had my new BMW factory engine for about 800 miles now, and am starting to stretch its legs a bit.
Unfortunately, the car still seems to run out of steam around 4500 rpm. I have checked the Weber 32/36 carburetor, and both the main and secondary valve are opening, but the secondary seems to be coming on at the very tail end of the pedal travel, is this normal?
I have a pertronix unit, with a 6A MSD ignition. The car otherwise is running great, nice and smooth...just a little disappointed with the acceleration.
Am I expecting too much, or should the car spin up the rpms with no problem?
Thanks in advance for any advice.
