Default New Forged 416 LSA how long before ring wash?

I have a newly built 416 LSA, All stock compression, with ID1050x, BTR cam.. I started it for about 40 seconds.. I noticed the fuel smell, I have a stock tune on the computer..Car sonded great.. but shut it off and I never retried.. I started looking up the fuel smell and noticed Fuel wash as a issue...I know LSA have oil squirters, so that helps with washing.. What are the odds I screwed it up with 40secs, I actually taped the start up so know exact time

Im going to change the oil, the oil didnt reek of gas, but Im taking no changes and have a tune scheduled.

Thanks for the help

Don't trip.... take it out with proper tune and make some boost. Those rings will seat themselves. Obviously don't run it with a crappy tune.

In a case like that with no tune, but it starts and idles ok if you have a wideband and an adjustable fuel pressure regulator you can turn the fuel pressure down real quick to get it idling at stoich. You will not want to drive it like that, but you can at least let it warm up and check for leaks etc before you start tuning.

Idling ring wash is not so worrysome. Its when you wind it up and the rings start to wiggle around under load that does em in. One good rip can do it, it doesnt take much.

I have the tune coming.. Im not risking it until I get that tune.. Im going to change the oil(doesnt smell like gas but want to make sure) and maybe squirt a little oil in each cylinder.
