A TCL First? '67 Rolls Royce project thread...

taking care of some last details before it hits the road...

almost done putting in the new ebrake cable. definitely a curious design with pullies and pulley brackets that require complete disassembly to thread the cable through


alternator a voltage reg are still at the electrical shop. alternator checks out but something is fishy with the regulator. they claim theyll be done testing/fixing before the long weekend but we'll see how it pans out...

i think i have all the knowledge/tools to get the idle and ignition timing under control when we fire it up again though, and with the new ebrake cable itll be usable around town!


sorry for the lack of pictures, not a lot to see with the ebrake cable change... just imagine two small pullies in an impossibly small area, and lots of fiddly work under the dash to disconnect the cable from the ratchet mechanism

sure did, made it outside for a bit weather was definitely amazing!

as promised, a few pictures from jim of the brake pump overhaul. you can really see how nasty the rear one was inside...











and the carb and ignition tuning from this weekend.
a few of these will probably look familiar to brit car nuts whove tinkered on other SU units before... but it was all new/interesting to me, so i figured id snap pics as we went through it









chris working his SU voodoo... and the rpm meter on the fluke proved priceless, as this all would have been impossible without a way to judge rpm.



and the hot laps around the lot for a final checkout of the mixture tune.




all around excellent progress this weekend. weve got the carbs dialed in, ignition timing done, carbs synced up and the idle speed all set up. engine response and idle quality are all awesome, the brakes are stopping the car, and everything seems to work well.

one snag though is a bit of a mysterious intermittent high idle after either running at higher rpms or after a hard throttle stab. the idle will only come back down after a few good whacks of the throttle to really move the rpms around.
right now were thinking something in the advance mechanism of the distributor, as nothing with the carb linkage, carb syncing, idle stop, choke, or vacuum leak wise seemed to bear any fruit... linkage isnt bound up, the throttle bushings are solid so the plates arent mis-seating, and the linkage is against the idle stop the whole time.
i did some quick searching and seemed to find similar symptoms popping up on a couple other forums, and talked to one of our friends who runs a british car restoration shop down south of here and he seemed to lean toward the distributor as well.

as a result ive got a line in to a lucas distributor guy recommended by andy (or local brit car expert) and we'll see if we can get this one gone through for peace of mind anyway. car is drivable as-is but i dont want to beat on the trans getting it in and out of gear at really high rpms...
planning to have all the other little details for road-worthiness sorted this week (like the front bumper! ) then we can chase down this high idle nonsense and enjoy some summer drives
