Good day all,
I’m bringing this thread back from the dead. The last post above, was posted nearly five years ago by my now late Father, Rick. I now have possession of his 289 Cobra and have spent far too long getting it back in fighting condition. I have spent approximately 4 weeks fighting this car to get it to fire. 3 years of stale ethanol-laden gasoline did a number on the Webers he describes above. I’ve been working closely with Mike from Pierce Manifolds in Gilroy, CA to get everything fully cleaned and dialed. According to what I read above, it sounds like I have some micro tuning to do with relation to the float heights. I have the floats currently sitting at 6mm but have not measured fuel levels in the bowls. I’m 1.5-2 turns out on the idle mixture screws and getting carb backfires on most, if not all cylinders.
Once I have those equal across all four bowls I’ll move onto the ignition gremlins I’m fighting. Thank you to all of you who have contributed to this and other threads. This has been and continues to be one of the friendliest car forums I have come across.
