Reprofiling the Cam on a 29

Unknown

I had a couple of interesting emails from a fellow '29 owner that I

thought were worth sharing. I am hoping he will join us on this list, but

until then I'll just post a few excerpts:



<< I have just installed a rebuilt engine in my '29. In the process I had

the camshaft re-profiled, and the difference is impressive, to say the least.

I can now climb hills in top gear which previously I had to change down to

second, and the fuel consumption has improved from 14 m.p.g. to 17.5, so I am

more than pleased. >>



This news excited me enough to ask for some more info:



<< I am using the original carburettor, but have reduced the jet size to

allow for the fact that modern fuel has less specific gravity than the 1929

grade. Experiment by soldering 5 amp fuse wire onto the ourside of the Jet,

folded back into the jet orifice. (Both high speed and intermediate jets, and

you can also fit an adjusting needle under the low speed jet. Before I did

this I was getting only 10 m.p.g. with the original cam. >>



What do you think of that? The best mileage my car has ever achieved was

11 mpg, and more often it is nearer 9. It admittedly has certain mechanical

problems such as leaky valves and a stretched timing chain so fixing all of

that and doing the cam would seem to offer the promise of a real improvement.
