Initial start question

[navyflyer72]

OK, Finally after 4 years the engine has been started, but when we started it initially the starter cranked nice and fast and after a few turns of the key and a few jabs at the gas pedal it came to life. But I have a question. After the 20 minute break in the warm engine is hard to start and requires about 10-15 seconds of cranking with a bunch of short stomps on the gas. It seems like it needs more gas to start? And the starter is slower to crank on the warm engine. Initial timing was set at 33 degrees, and even going back about 3 degrees made no difference. I was wondering if not having the electric choke hooked up yet would make much difference. The engine is a 327, that has had a lot of work done to the heads for flow, new internals, balanced and blueprinted, blocked and decked, crank cut .010, bored .060 over, compression is only at 9.5:1, Edelbrock air gap intake with Demon 650, MSD HEI and 6AL with an MSD coil. Fuel pump is an Edelbrock electric pump and an Aeromotive filter. Any ideas to get a smoother start??? Also ideas when to get a keyed hot wire for the electric choke? Thanks ... Oh, yeah she sounds REALLY nice with the 2.5 inch Magna flow exhaust, I love the sound.

Your initial timing should only be about 16* the rest should be in the mechanical advance to get you to approx. 36*- your full advance around 2800 RPM. If you are at 36* initial combined with a warm engine, it will create more cylinder pressure and be harder to crank over. Make sure you don't have the vacuum advance (if you are you using any, and you should) hooked up to a vacuum source while setting the timing. Also, now that the cam is broken in, set the timing at an idle RPM. If you set it at a "break-in" RPM (2k) you will be into the mechanical advance.
