Smoking

[DianneB]

I just did the engine on my '67 Dream - honed cylinders and new rings - and it was doing the same thing initially.

The rings I got were not bevelled so there is no top/bottom.

I was advised (by a race engine builder) to run a tank of gas/oil mix for the break-in and the mixture was also excessively rich so it was pretty smokey.

By the time the first tank of gas was burned I had the mixture sorted and it is running just fine now.

I have been around engines my whole life and never heard of "glazing the cylinders" from a rich mixture so my advice is to fix your mixture problem and give the engine a reasonable break-in time before worrying about smoke.

Thanks, that`s exactly my plan. Tim is right I guess, too, the super rich mixture can wash the oil off the cylinders and may lead to excessive wear that is manifested in glazing. But i think that requires a bit more time of usage than letting run the engine for a couple of hours total in the garage. Now I have to figure why my mix is so rich. I suspect the needle jet holder and needle pair, I read some posts here and it is still not clear to me how these two have to be positioned to each other. Also, when I rebuilt the carbs I got them soaked in carb cleaner and forgot them there for a couple of days, and the stuff dissolved off a bit of stuff other than dirt that may be the problem too.

What rings did you get?

Don't remember specifically but think they were after-market replacements.

Usually rings even after market for these engines have a top with LITTLE/SMALL letters/numbers.
The top ring is usually silver and the second black then the oil ring.
The first has a small cut back on the top and the next one a larger cut back on the bottom.
Did you look for numbers/letters?. ..............lm
