Help with Timing, Vacuum and Backfire - 289c.i.

Did you try a compression test?

That should show whether or not you are the valves are seated... It would be difficult to look at it and know, unless something was severely bent... or if you were to have lost a valve lock.

Am I to assume that you are running a hydraulic cam? If that is the case, double check those adjustments... After running the engine for a minute or so, you should be able to spin the pushrods on valves that are seated with your fingers. If you can't, back it off a 1/4 turn and try again...

As to your English, I'd try to answer you in Spanish... but it has been so long since I spoke it (about 10 years), I'd end up embarrassing myself and unknowingly insult you...

LOL!!!

By the way, what the heck is going on down there? Looks like the entire South American economy is taking off... Is it going to be for real this time, or another boom and bust?

The compression test that I do after the re-assembly was Ok, if I remember Ok, all cylinder were around 125' +/- 5% (this, the 5% I remember well).
The cam is a Hydraulic one, so Im gona try with the valves/lifters finger test on saturday.

About the southamerican economy, it is true, it seams as is taking of, but I think is just another ballon efect. Let see in a couple of months.

Are you sure that your Spanish is worst than my English? I'm not.
LOL
Thanks again.
