In the final stretches of this job. The change from random construction to finished work is always fun. There's still a bit of work to be done, but I can see the end, rather the splishin and spashin behind the boat.
Awesome. glad to see the end is finally near......

I have been waiting for this post for sometime now. I felt a little bit of relief after launching and a bunch after recovering the boat. We are having some issue with the engine I think I have a fuel delivery problem and we did some diagnostic to it on the water but I need a fuel pressure check to begin with. Other wise it went out and came back in under its own power. We just don't have anything over half throttle. Like as soon as the 4bbl kicks in the engine speed decreases. As soon as I back out it comes back up to speed. All work for another day I wasn't real impressed with the carb rebuild this go around so it could be a carb issue also. But we did't sink, it ran, and the deck layout worked out real well. All positive in that light and for a shake down it could've went better but it could've been way worse.

Your carb needs work as the secondary jets are probably plugged

Sounds like timing to me did you check to be sure it's advancing properly?

Guessing "Had" is have right?

You could do it, not that hard
Had was the correct tense. The guy who rebuilt it has never let me down until this time. He's been building carbs as long as I've been alive. For some reason though this carb has just been trash.

I'll get it figured out. Timing was a issue, I forgot about the base running plug thing for setting the EST distributor. It was the 1st run since being layed up for 6 years there was bound to some problems. Is only ever ran on muffs in the driveway until last week. You can't tell much until it's in the water.

FWIW, I rebuilt a carb, set it on the shelf in the garage for about a month, insects built a nest in the vent tubes on both bowls and filled the carb with enough dirt that it wouldnt run right when filled with fuel.

I but it was sealed in a plastic bag to avoid those issues. I'm kinda hoping the fuel pump is just weak or there's something in a fuel line somewhere. The thing idles buttery smooth. It'll be something stupid in sure.

It's in the secondary jets/metering
This is a rochester q-jet BTW it only has one bowl. Secondary jets are all clear. What I did find was there was a catch in the doors for the secondaries that I corrected when I reassembled the carb. I also lightened up the tension on the secondaries a bunch. Also there is a dash pot that restricts the actuation of the secondaries under a certain condition. I'd love to know what it is for. I've got to replace the drive plate there's a noise that I believe is the sound of a cracked drive plate.

The dash pot keeps the secondaries from opening under high vacuum (light load). When vacuum is reduced under high load it releases

If you plan on keeping the QJ, I highly recommend getting Cliff Ruggles' book and Doug Roe's book.

And you are right, there is only one bowl, but there are secondary wells that are fed from the bowl through two tiny holes, which can get clogged.

All that is clear. I think the problem was up top with the air doors for the secondaries. The gasket for the air horn was fouling the movement. A quick trim with a razor blade and its all smoove again.

The newest addition to the ongoing project. Should make egress to/from the boat easier.

Yeah I have $360 for the thing. I made a highly technical contour gage to decide if this had enough meat to make it fit the boat. Just got to get the spacing and level right.

I think this is going to be how it sits on the boat. I got the deck coped to the transom hopefully have this thing ready by Friday for some time on the water.
