Hello, as my build gets closer to completion I have been doing a ton of research. I have never personally owned a vehicle with a carb so a lot is new to me. My main concern is how critical is it to break the cam in on the first run. Reason I ask is because I have never had an engine built before and have never timed one or set up a carburetor. I am seeing where people are saying its absolutely critical to run the engine immediately to 2000 rpm for 30 minutes to properly break in the flat tappet cam. I'm just hoping I can get the engine running properly quick enough to do the break in run. Thoughts?
