I have put my 272 Y block back together after a rebuild, only to come to break-in and she won't start. Just seems like a timing problem. As I don't know too much I'd thought I'd try the collective knowledge of you y blockers.

Now regards to ignition/timing, I have a new cam, valve springs, timing set, crank dampener and MSD distributor and coil and new leads and plugs.

Bit of insight-

I set #1 piston at TDC compression stroke and counted 12 pins between timing chain marks. The new dampener's timing marks also correspond to #1 TDC. So at this stage I'm looking good. I marked where I wanted #1 lead on my dizzy cap, transferred it down and dropped the dizzy in with the rotor pointing a #1. I then cranked the engine by hand until piston #1 was at compression TDC and checked rotor was still pointing at #1. All good.

After checking a few thinks I tried to start the engine... I threw a tiny bit of fuel in the carby and cranked her over. Nothing- kept cranking until fuel was fully primed in carby. I then left it for 15mim to think and tried again, still nothing but a couple of coughs.

I'm not sure if it has anything to do with the new MSD dizzy and coil or something I have done wrong.

Any help would be appreciated. Thanks, Dan.
