Running at half choke is a typical condition until the engine is fully up to temperature. If you are driving it less than a mile or so, it will not warm up enough to push in the choke.

Pete, Many (if not most) owner drivers replace the original cast iron pistons with aluminum pistons. This reduces the rotational weight of the engine and increases the original engine power by about 10%. Modern rings and wrist pins also reduce friction to increase power while reducing wear.

Most oil pumps cannot produce enough pressure due to wear on the flat plate that supports the gears. You can make the plate flat again to renew pressure by sanding or grinding. Just make sure it is smooth and flat when finished.

Does it turn over with the priming cups open?

A hand crank for a large series straight 8 engine is totally unnecessary. Jog the starter or pry on the ring gear to set timing etc. Just don't ever try to start it with a hand crank unless you want a hernia...

Graphite only...

Pull the string packing and measure it to determine the annular space size you need. Wrap the packing around the same size shaft or wood dowel and angle cut packing rings to fit tightly end to end on the pump shaft. Pre-lube with waterproof marine grease and insert three rings with cuts 120 degrees apart. pump packing | McMaster-Carr

I suggest you first check your freeze plugs for leaks.

Great parts cars or speedster makings... Looks like 1923 models?

Andrew, Perhaps a previous owner replaced it with a more common badge. McLaughlin badges are much harder to find.

Torque settings are also dependent on new or old (reused) fasteners. Reused fasteners are already stretched and will often fail before reaching their originally specified torque settings. Torque is also affected by weather the fastener is lubricated or not. Many old bolts do not have a raised machined mating surface that would qualify as a fastener for specific torque settings.

Check for a rusted-out cotter pin or disconnected valve.

Unless the switch is just to activate via a solenoid as above, the switch should be rated to exceed the 6V amp load. 6V systems require double the amps of 12V systems.

I have a Frigidaire fridge in my man cave at the Buick Barn. It still works too.

Take it easy Dave. Just kick back and watch the forum for photos and videos like the rest of us... Get well soon...

Dan, As far as I know, there are no plans or kits to replace the wood in these cars. Unless you are a skilled wood worker with all the shop tools needed to do compount curves, finger joints, etc..., you will be challenged beyond your limits. If the wood is good enough for patterns, you still have a chance to make it happen. Otherwise I suggest you find a GM body builder that has done other GM cars. Good luck,

I believe you guys are overthinking this process. Feel each rocker to find the ones no longer under tension. Or, you can watch the valves open and close as a helper jogs the starter. Adjust the loose ones and mark the adjusted ones with chalk as you continue to jog the engine and adjust until all rockers are marked as adjusted. Double check with an old (beat up) feeler gage with the engine running to verify they are correctly adjusted.

This is a much better response for for someone who didn't include the year and model in their post. Your change in the Technical section is a bit harsh by using all caps in red with a exclamation point. "REQUIRED: Year, make, model, and technical issue in the title!" You already have a reputation with me & many of my forum friends of being too harsh. So, I suggest you slow your roll by substituting a few words like please and thank you.

30 years ago I used crushed pea gravel, hot water & Drano drain cleaner. I took my 29 Buick tank outside and shook it for about 20 minutes in all directions. Dumped it out, dried it and put Bill Hirsh's tank sealer in it. That Buick is still on the road with no issues. Just 3 years ago I took my 12 Buick Roadster tank to a friend who put water & ceramic abrasives in it and put it on his shaker table overnight. I had to solder a few pin holes before putting Red Kote tank sealer in it. ALCOHOL RESISTANT GAS TANK SEALER GALLON | Aircraft Spruce Damon Industries Red-Kote Gas Tank Liner (damonq.com)

Yes, thanks... Mark

Dave, I called Rand and no luck. He only makes the float bowl covers for Marvel carbs. Any chance you could send photos and dimensions so I can cast my own in aluminum? Thanks, Mark

Like this one?

Got a photo??
