Cylinders washed need help

[Ryanbrown36]

I’ve recently completed my Sbc swap and just threw a new carb on it and it fired right up but was running a little rich, I went out yesterday to adjust the carb and I couldn’t get it to start after leaning it out (it was also very cold out) so played around with it and put it back to where it was set at before and didn't want to start and I now smell gas on the dipstick, I’m guessing I’ve cranked for maybe a little over 1 minute total (probably giving more gas than I should be but wasn’t thinking and I’m new to all this) how worried should I be, and what can I do now to fix this. Thanks

The easy solution is change the oil. But it’s subjective. I can’t imagine it dumped that much gas past the rings.
But did you pull some plugs and confirm that it was grossly flooded?
Also gasoline evaporates, so even if you have some gas in the oil, it will effectively disappear.

I didn’t at the time but I just pulled #1 plug and this is how it looks. I honestly don’t think there could’ve been much that got past either but it’s basically it a fresh motor and don’t want to do any damage.

It is possible to wash rings out of a new engine. Way rich, although probably no damage has been done yet need to fix whatever is causing it. Hard to see what carb is on it Carter?

It’s a Holley 600 cfm street warrior, when it first ran the accelerator pump was way off but did run fine just high idle, if I lean it out and set the accelerator pump and idle to a factory setting would you recommend trying to start it or are there other steps first?

check fuel level/float/ idle mixture, running. Should be fuel just below opening, side of bowl. Accelerator pump only works during acceleration. Idle mix screws adjust after float level. Gradually lean them out until RPM drop then out 1/8th to 1/4 turn. May need to go back and forth or side to side a couple times.

I already set the float height like how you said and did the mixture screws, I will adjust more like you are saying when it runs again. Do I need to do anything about the cylinder wash or do I just need to get it running again and tune from there?

Change the oil if you're concerned.

From the specs in your other thread it's probably gonna want a lot of idle timing. Make sure the vacuum advance is hooked to manifold vacuum.

I square up the transfer slot and adjust idle speed with the rear secondary screw from underneath. Sometimes it's a straight screw and sometimes it's an allen head. After adjusting the mixture screws you may have to go back and readjust. I shoot for highest vacuum using a gauge. Base setting on a 2 corner idle is 1.5 turns out.
