Slant 6 won’t start after 4 months

Did you remove the distributor? If so then it sounds like you need to restab it.. so you need to find TDC compression stroke.. you can use your finger or..well, with one person you can still use your finger on a slant LOL but otherwise I like to hook up a compression tester and it doesn't take much just finding that compression stroke when you push that button it still gives a little tiny puff and tells you Yep this is the compression stroke. I work 99.9% solo mostly. Then pull the cap off the distributor and see which way the rotor is pointing in relation to number one terminal on the cap
That’s gotta be it. I did remove the distributor! I’ll try re setting timing tomorrow
