Thanks for the update, @71_GT ! I think you got all the bases covered. If you got your 20min break in completed successfully, you're probably good. You'll fee even better if you drain the oil, watch it closely for glitter, and cut open the filter to see if there's debris inside. If you pass that test I'd say your in the clear!
Almost spoke too soon. Noticed backfire out carb when hitting gas from idle. Finally tried to take it down driveway but it had no power to even take off and constantly backfiring. Spent 2 days pulling my hair out and asking for help. Engine builder said I was off one tooth on timing. I changed to every tooth I could find and nothing worked. The day I picked up the engine he told me he put a cam with 351 firing order and gave me a tag with new firing order. At my wits end, I took some friendly advice to try the 302 firing order and it sure seems to have fixed it. Now it idles on 10 degrees timing where previously the only way it would idle was.about 30 degrees.
Hmmm...so he lied about the firing order. Don't be surprised of your sparkplugs are fouled. You really need to know what the total timing is, and use initial for quick reference...
I am and I’ll ask this while I’m at it. I’m on totally mechanical timing my 4412 Holley doesn’t have a ported vacuum. I’m thinking of running vacuum advance off the manifold. Anyone with thoughts?
