There are several vacuum brake set ups for Q-jet. As long as cold starts lean out well and secondaries open clean, all good. Old carb had primary secondary, new is all on the secondary. I like vac advance controlled by intake signal. I find that backing off dist. past ping does the job fine.
I have used manual retard control in the past, Mallory I think. Just the ticket if you get some weak gas.

Steve, Just curious as to what background you have that enables you to do so many different things. I am jealous

Steve's knowledge base is pretty impressive. What truly amazes me his abilities to diagnose problems, work out a solution and then fix it in an incredible short period of time. It'd take me a week to do what he does in a day.

Could someone help me with this item? This actually is a picture from Steve's engine, but I have one just like it on mine. Mine is empty and I would like to fill it with something but I don't know what it goes to. Is it part of the Power Steering or Brakes or something else?

The Chevrolet Motor Home Chassis Service Guide calls for Power steering fluid, GM part no.1050017 or equivalent.

Thanks. I sort of thought it had to be power steering but I didn't know for sure. That is something lacking in the owner's manual. The dipstick is dry except for one little drop on the very bottom. This old motorhome is not going to be roadworthy until next summer, after I duplicate Steve's projects. However I doubt I'll be able to do it in 46 days!!!

The answer to the question on my training - I was a computer programmer so I can work things through in my mind until I get an idea
No pics today as it was all about the road test and tuning. jim83itasca is helping me out with some techie stuff in the Tech forum.
I tuned the base timing as stock 4 degrees today - found that I could just see the pointer on the top of the engine and so used #1 cylinder.
Was going to go for a drive but it wouldn't even move off the lot - engine dies as soon as you give it throttle. I checked the vacuum advance (getting 18-20# of vacuum at idle)and it was 10 degrees so that gave me 14 degrees.
So I slowly rotated the distributor giving it more advance and pickup was a lot cleaner so took it out onto the road. There was slight hesitation as you got onto the gas - the transition from idle to power, but when on the power it performed well.
So then I tried the secondaries.
As soon they opened, the engine died for about half a second and then took off like a scalded cat - only problem was that it sounded like a bucket of nails there was so much pinging. So I pulled over and retarded the timing a fraction and tried again.
This time the hesitation from idle to power had increased but there was no pinging under WOT. Still the hesitation when the secondaries opened.
So I'm thinking that the mechanical advance is not coming in soon enough - the weights look pretty wimpy and the springs quite strong and so I'm guessing that it was set up for a regular car (350) where 3500-4000 rpm would be normal whereas the 454 never really gets past 3000 rpm.
So tomorrow I may swap the weights over from the old distributor and try them until I can order a new set more appropriate for this setup.
Ah, the trials and tribulations of working on non-computer stuff
