===================================

If you failed to prop the throttle open, and the engine was dry, the
compression will be WAY LOW. You may have damaged the igniter too when
you cranked with the wires disconnected. Have you listened to the fuel
pump, and tried a bit of starting fluid to see if it will fire up even
for a second?

Soooo, find out WHY its so low!

Start with a leak-down test. If there are components leaking that
shouldnt you can find them easily with some smart listening.

Leakdown testers are available for under $100 and I just saw one very
cheap at Harbor Freight in their recent sale flyer. If you do ANY engine
work this tool will save you LOTS of guesswork.
