Yes.
The smoke generator produces a very low pressure.
So I will try connecting the air pressure (starting at a very low setting) to the vacuum system directly and see what I get.
But not sure if it will replicate the sound though since it's created by a vacuum.
And it's time to replace the ignition switch. The last one lasted almost six years,which I understand is very good for the new ones.

You mean missing grease on fiber part of points / shaft?
Remembering, yes, that can make loud noise.
One good drop of oil inside the center of the dizzy-shaft can also be a good thing.
Vacuum hoses around and to air filter? |

I hadn't thought of that possibly being the problem.
While I'm pretty regular at adding a drop of oil on the dizzy shaft, it doesn't hurt to add a few more. So I did, but no change with the squeal. Thanks for the idea!
I have also wiggled all the vacuum hoses many times and smoke tested them, so I'm pretty sure they're not leaking.
Now another issue popped up this week...
When I would turn the key to the start position, the dash lights would come on, but no click, no crank, no nothing. But every five to ten tries, it would finally crank and start up normally.
Since the ignition switch is about six years old, I replaced it with a new one that I had bought at the same time as the one I removed.
But the same no-start issue remains, with it taking numerous turns of the key before starting.
Is it possible the lock cylinder needs to be replaced?
Or am I missing something else?

hey kent,
i’ve only got the obvious.
battery voltage?
amp draw on the battery when trying to start?
hope you sort it out, and get back on the road in that sweet bus.

not starting? is it cranking and not starting or is it not cranking,check the starter for power at the s terminal while someone turns the key to the start position,chech all connections including grounds ,if no power going to the s terminal ,check the circuit back to the ignition switch,

Same result with a fresh switch says there's a loose or dirty connection somewhere in the chain, time for some wiring terminal fiddling.
The distributor squeak is often from the point rubbing block, but can also come from the bushings in rare cases. But the way the squeal drops off for s split second when you crack the throttle says to me it's vacuum. Maybe connect your shop vac to the manifold/S boot (throttle open) and pull a real vacuum on it to try and make it squeal, then you can listen with a tube to isolate and dribble non flammable liquids (water?) on suspect spots to listen for a change.

Could the starting issue be the ground cable?

Battery ground cable, that is. It was an issue on my 71 that took a while to realize.

Yes it could, one single broken link in the chain can cause a no start, each end of each main cable as well as the transmission strap, and all the connections on the starter can be an issue if any single one is dirty or loose.
And no "looking at them" either, physically unbolt it, shine it up if there's any white or grey stuff and reassemble with a fresh blob of grease spread around over all the parts that touch each other as you assemble.

Hopefully a quick one...
Taking my case to the machinist this week to have the bores checked and for cleaning...
Is it best / polite to take it to them with the case halves bolted together for checking the bores? All the fasteners, or just the six main bearing bolts?
Type 4 case - thanks!

The six main bolts (properly torqued) are all you need.

Whatythe difference between an H30/31 and a 34pict-3? I have seen both of them mentioned for 1600 bus engines.
Excuse my ignorance.

30/31 is used on single port engines, 34 on dual port engines. '68-'70 Bus engines were single port. '71 Bus was dual port.
The bottom flange of the 30/31 where the carb mounts to the manifold is smaller. There are differences in the vacuum ports also.

Once again you nailed it, BusDaddy.
I went thru and cleaned/tightened all the connections, and it started right up.
So I replaced a good ignition switch with another good ignition switch.

Thanks Tom.
I also checked the voltage which was a little low, so stuck the charger on for a few hours.

Finally getting to the point with my rebuild where I seriously have to look at sourcing some main engine bearings.
One of the sets I've come across - which looks on first glance to be better quality, but who knows - is advertised as having oversized thrust, but there isn't a number on it.
My assumption (yes, I know, root of all f*ck ups) is that this means an oversized thrust surface, as opposed to a bearing which is wider (fore-aft?) than standard to take up excess endplay.
Am I on the right lines?
