stacks stumble
Need help tuning hilborn stacks, car idles ok seems to have good response revs clean but when throttle is rapped it blows a cloud of smoke.
Took car for a road test and stand on it, it takes off and then lays over and dies then picks up and stumbles like a bad misfire.
I've tried riching/leaning with no luck.
Any advise on what to try would be appreciated.
