OMG WTF, if it's not one thing it's another Options

so we've been battling a tuning issue which is being discussed in another thread, so I don't want to muddy the waters with another issue, hence the new post.

So, i'm sneaking up on this carb tuning issue and get the car idling to do the carb tune stuff and I notice this shxt...

I get the car started, rev it to 2-3K for a little bit until it establishes idle at about 1,200.

so I get out to start fooling with the carbs and notice it's not smoking with white smoke like it was the last time. Outside temp was about 50, now outside temp is 64ish.

It's freak'n spitting out oil. There is a spray pattern out the tailpipe about 12' long.

When we filled the oil I instructed 4 qts but not sure if son put in the whole 5 qt Mobil One container in. Also, on initial run he thought it was a little low, on oil, so we put in another 1/2 qt.

Engine has been sticking a (measuring) really high ever since.

Has a piston ring gone south??

Is the oil overfill causing this issue?

Why did this just start happening?

Good job - making progress.

So the 32mm venturis are on the big side to get good driveability and snappy throttle response. They will work . . . but here’s what you need to know. With that large of a Venturi throttle response is going to suck (did you catch that pun?). If you quickly blip open the throttle. It’s going to go lean and will stumble or possible random smidge of a backfire. As you seek to tune the idle don’t get distracted by blipping the throttle and seeking a perfectly smooth transition, ain’t gonna happen with 32s.

You should still be able to get to a smooth idle and a decent transition if you open the throttle smoothly and a little more slowly than just flipping between idle and wide open throttle.

There are a few tricks that can help ease the situation by trying to increase the quantity of fuel that the accelerator pumps release but that is more like the Jedi master class. Don’t get distracted by the quest for smooth seamless transition to fast throttle blips.

yes I got it, and yes it sucks. everything you've said is exactly what's going on.

carbs are all snyc'd on all four corners, with that said I wish I had not cheaped on the snail gauge and got the pricey one.
