Luckily I did it in front of a few dozen others, and was called out by the good people in the audience. :)

I live-broadcasted my short block build two weeks ago for people that were interested in seeing how it all goes together. I was torquing the first main bearing nut when TomWesty (I think) called out three cam bearing shells behind the case all cleaned and ready to go. :silent:

What shortblock build?
Why are you building a short block?
Is it your own?
Is it a customer's, like NYCynthia's?
Is it a spare?

Mine.
I'm heading to Illinois this spring with the Colorado Rebuild. (JB Weld bearings, heli-coil-plugs, used camshaft…) I will have this new engine on standby until the week I leave for my trip and have that conversation with Buddy.
Yes.
No.
Yes.

Time for an update for my glacial-progress thread here.

Had a visit from Colin a couple months ago, we went over all my new engine parts and he set me on the right path for what I need to do to get my short block put together. And no, I haven't made much more progress on it, lol. We spent a few minutes wondering why my bus wasn't running right, and we found tight exhaust valves. This was a surprise to me, as Robbie and I had done the valves around 1,000 miles ago. Anyway, it idled nice, but we didn't drive it.

I took it out a few days later and the same problems crept up. Stalls when you take your foot off the gas. I said screw it and sent the carb to Volkzbitz.
This piece of art came back:
Image

I went to install it, and oops. Accel pump linkage hits the alternator. I didn't think to tell him I had an alternator when I sent it to him. So I send it back for the correct bracket and linkage. I get it back in the mail, crap, now I've lost my barrel clamp for the throttle cable. I've got quite a stash of random parts, maybe I have one somewhere. Finally find one attached to a heater box. As you can see, I'm also installing the correct throttle positioner pieces. I do a bit of research to see what hose goes where. Oh, one goes from the "altitude corrector" to the intake manifold. Hmmm, no tube anywhere on mine except for the brake booster. I knew it wouldn't be that easy. Back to the parts stash and find this, score. Now, can this be removed and installed without removing the engine or the center intake section?

Yes.

Please please please be very very very sure that the intake port surfaces and the intake manifold surfaces are magnificently clean in a truly outstanding way. You are using aluminum gaskets that are not forgiving of crud, dirt, old gasket material, etc.

I look forward to driving that bus if I ever ever ever decide to subject myself to eastern moisture ever again.

Any update on this build? I am ruminating on a 1776 build and Mexican fuel injection too. If you used it - how are you finding it?

That's IT. NO KARMANN GHIA FOR YOU.

You're traumatized. The bus engine saga did that to you.)

Traumatized? Yes of course! But not by wonderful, stable and predictable fuel injection! We may be turning the Ghia back into a daily drive and I think this can be done sympathetically and without hackery. Mexican fuel injection does not need much more space than current configuration. I would keep the '71 oil bath and HE/Muffler.

Another update for this stupid engine. I installed the beautiful carb, and I can't seem to get fuel to flow it. I replaced the fuel filter, and fuel is flowing out of the tank. It starts and runs when I dump a bit of fuel in the top of the carb but cranks forever otherwise. I've even taped off the top of the carb to try to get vacuum to help pull the fuel but no start.

If I can't get this thing started while there's few nice days remaining, I'm going to pull it all and do the Mexican FI over winter. I should've made an appointment with Colin this past summer

I followed it and forgot half my crank dowl pins. Oh to have an audience..

Andy - if you're anything like me then you'll benefit from a numbered checklist you write yourself for case assembly. Then find the time, space and patience to build and seal the case in one go, checking those steps off as you go. No interruptions.

Fill the carburetor bowl through the little vent pipe, using an eye dropper, about twenty repetitions should do it, but if you see fuel begin to drip into the throat, stop right there and try to start as immediately as you can after putting the air filter back on.

Did you rebuild the fuel pump, or have it rebuilt? Feel free to tap the carb lightly at the fuel inlet while it runs the fuel you put in the bowl.

And we do not have to ask you if the inlet to the pump comes from the tank, and the outlet from the pump goes to the carburetor. Old style pumps inlet is on bottom, outlet on top.

This is an old picture from when I got the bus so don't judge me on it, but it shows the fuel pump. The outlet is on the bottom and inlet in the top, it's always been that way. Is that correct for this pump?

That looks like the same new style pump I have used on several cars. In the top, out the bottom, just like humans take in and expel liquids.

Have you added gas with a dropper yet?

Did you check that the pump is pumping? You mention fuel flowing from the tank so I wasn't sure. You can remove fuel line from the carb, and with key off, turn engine with a wrench. Fuel should spurt out. Make sure you put the hose into a container! You appear to have an alternator style pump. You didn't accidentally leave the pushrod out? There are 2 pushrod lengths. A short one, 4" for alternator and a long 4.25" for generator. If you use the long one in the alt. pump it will damage it.
The alternator pumps cannot be rebuilt. There is also a chance that the pivot pin on the lower part of the pump has come out. If this is the case, you can fiddle it back in and peen the pump body to hold it in.
