Bama -

What you've got is an H originally setup to run on distillate (hence the small gas tank for starting)

I've fired up several H's and M's that have been sitting idle for several years. Here's how I've done it:

1 - Check the crankcase oil level. If it's down, or the oil looks questionable, drop the old oil and replace with fresh. Also put in a new oil filter.

2 - Remove the spark plugs and shoot an ounce or so of motor oil (several squirts from a hand oiler) into each jug. Leave the plugs out for now.

3 - Connect the battery and try cranking. If you are lucky the motor will spin. Crank it until oil pressure shows on the gage, then crank it another 30 seconds or so to distribute oil up into the valve gear in the head. Keep an eye on the starter - let it rest if it starts warming up!

4 - While you're cranking, listen for the mag impulse coupling to "snap". If it snaps - great! If it doesn't, take it off, clean it, oil it up and put it back on.

5 - Remove the sediment bowl and clean it out.

6 - Dump a couple gallons of fresh gas into the large tank. Open the fuel shutoff a moment to make sure fuel flows, and to flush out any crud.

7 - Replace the sediment bowl (use a new gasket on it - the old one is guaranteed to leak!) Now open the drain cock on the carburetor, then open the valve at the sediment bowl. Again if you are lucky you'll get some gas draining from the carb. If not, you're gonna have to open the carb to clean it or fix a stuck float.

8 - Finally replace the spark plugs. Set the governor at 1/2, pull the choke and crank her up. If you're having a good day you'll be rewarded with a running H.

9 - If it fires up, don't let it run more than a minute or two until you've filled the cooling system with water.

Good luck! ...Bob M

PS - Before you do anything, check for wasp nests up under the hood, in the clutch housing, behind the radiator, etc. Otherwise you may be in for a NASTY surprise! (I've been there a couple of times...)
