Tinkering with the Scrambler

Stealing away some time, I've gotten small things done on the scrambler.  The oil tank has been cleaned and re-filtered.  However, the paint washed off in a small section on the face of the tank.  There is evidence that it might have been re sprayed with aerosol cans in the past.  I've tried my hand at brush painting it with moderate success.  
There were a few observations to note while preparing the oil delivery and return.  On the feed line was a brass shut off which didn't make much sense to me. I've found that most of the time the ball check valve works just fine.  And on those occasions when it wet sumps,when the oil is cold and heavy, it might not be a bad thing.  Just drain it out.   
When Floyd had parked his MAC in the basement for several years it had wet sumped. I wonder if having the crankcase full of oil helped preserve it while being dormant for so long.  Anyways, in the case of the scrambler, the ball valve was missing both the spring and ball. That would explain the brass valve!  The ball seat was quite beveled and and I recalled that when working on the MSS years ago that Ed G mention that the seat needs to have a somewhat sharp face to work properly.  So to the lathe for a quick refacing.

While pulling the old lines from the fittings, I noticed that the clamps were stamped 'CHENEY 00 made in England'  could this be an original clamp?

1967 Velocette Scrambler Project Continued

Trying to fight off the winter blahs I got back into the Scrambler's reassembly.  With a bit of motivation and positive forward progress maybe we'll hear it this spring. All of the major bits have been serviced (Forks, Engine, gearbox, magneto). So it should be a simple put together?


 While getting back into the dry build, one chore will be making new cables for all of the controls. It was apparent pretty quickly upon mounting the carb that the routing for the throttle and choke cable
have an issue.  The previous carb was a concentric with no choke and the original was a 10TT9. The Monobloc seemed to be a good compromise between the two, other than the routing of the cables.



However both the cruxiform rubber support block and the rear tank tabs interfere with giving the cables a clear shot out of the carb; the choke having the worst of it.  The initial thought is to modify a new support block and dremel off a corner of the tank support.  Hmm, we'll see how it goes.  What would you do?

1967 Velocette Scrambler air box (detailed photos)

Ed G asked if I could set a few pictures of the scrambler air filter construction on the blog, so here they be. It is an interesting construction, seems Veloce' was using two standard air boxes and then sandwiching them together. I've included in some of the pictures the 1963 MSS airbox filter.
