Re: Flathead low intake vacuum
Try a squirt of starting fluid (ether) in the carb while cranking. If the engine fires on that it should keep running on gas. If you get it running, drizzle some MMO in the carb while jazzing the throttle to keep it going. Run it up and down for 20 minutes or so. Then run your compression check again. It could be considerably better. Remember to leave all of the plugs removed and block the throttle full open to get the truest reading.
