Though your compression may be good, it won't be long before your friend just says no!, forget it, I can't do it anymore.

I can appreciate what you're saying, I really do.

Yeah that's a lot of miles, but those are some of the most well maintained miles on the planet. I have changed the oil and filter faithfully every 3000 miles since day one- several times I did go more than several hundred miles over 3000...rarely more than a thousand. In all those years and miles- if you divide 345K by 3k, you get 115 oil changes-my records show I've done 99.

As a dealer service adviser for many different makes over the years, I have seen my share of high-mileage cars. The common thread for all of them was a fastidious maintenance history. The service records for this truck fill a one inch binder.

I get what you're saying about the motor being worn- for most vehicles. This truck is not in the category of "most vehicles" though.

In reading all these responses, I am starting to conclude that this thing just needs to be handed over to a Weber carb specialist for some fine tuning. The factory mechanical pump is not providing too much pressure or not enough volume...the Weber just needs some tweaking. It remains in the "out of the box" state of tune.

A couple of hours of labor by somebody who really knows these carbs will work wonders for it, I have come to believe...

P.S. You guys are an extremely helpful bunch, and I truly appreciate all of your inputs.
