49 farmall starting trouble

49 h is turning over but not starting. Has eight volt battery so charging is trouble. Tried for a while and battery is low now. Flushed tank put new fuel filter. Tried some starting spray and got. A bit but no full run. Sat for about eight months. Also once it tried to start the starter whirled any suggestions?
 
I'd try a couple of easy things first. Pull the plug on your carb and see if gas will run for a minute or so. If it flows you don't have a pluged fuel line. You could still have a carb problem from sitting and jets gettng plugged up. Pull a spark plug, turn over th engine and see if you have spark. You could have corroded points from sitting. If neither of things finds an issue you could have bigger problems. You do need to have a battery with enough power to turn the tractor and fire the plugs. A weak battery often can't do both.
 
agree with charlie - after sitting for 8 months, it's a given that you should clean up the points, just becuase. Just touch them up with some very fine sandpaper - nothing crazy, just enough to kind of "wipe them off".

Also pull each plug, clean it off, and make sure you're getting a good spark to each.

Though it does sound more like a carb issue.

First of all - fuel filters are generally not needed and only introduce another weak link. If it can be removed from the picture easily enough, i'd do that. If not - just be sure fuel's flowing through good.

I'd pull the carb off, take it apart and give it a thorough cleaning - clean out all the little passageways. Then start fresh from there and see what happens.

With a known good spark in all cylinders, and a clean carb - most likely it'll fire up.

Tip cleaners work well for tiny passages (sold in packs for use on torches - any home depot has them)
 
Seems to me if you got it running on starting spray it's either a fuel delivery and/or a carb problem. Keep in mind H's have a gravity fuel flow system with no pump. A filter in the line will usually cause excessive flow resistance. There should be a glass cup used as a filter at the exit of the fuel tank. Anything more than that will cause problems. As stated, remove the plug at the bottom of the carb bowl and you should have full flow our of the hole. Once you have good fuel flow, take the carb off and give it a good cleaning. It doesn't seem like it is the porblem but taking the distributor cap off, LIGHTLY sanding the points and resetting the gap cannot hurt a thing. Be sure the inside of the cap is dry before reinstalling it. Goo Luck.
 
Clean the points with some 320 wet or dry until shiny. If you have a distributor your battery voltage may be too low for your ignition. Try a fully charged battery. Hal
 
Thanks everyone for your suggestions. Much appreciated. 1st the fuel filter I was speaking of is the glass bowl and not an additional one, second the battery is an 8 volt, not sure why, and I don't have a charger for it, they are hard to find. I was considering going back to a six (bought the tractor with the 8 already there) because I can charge the six. Any thoughts on that?
Today I checked the fuel, nd there is fuel to the carb , it leaked from there last night, so fuel gets to it but not sure why it's leaking. Cleaned the plug wireS, but the points don't look like the ones in my manual, so not sure where to clean them.

The battery. Is getting low but the weird thing is it cranks and just sounds like it is ready to belch and start when the starter clicks and then souns like it is spinning real fast like a freewheel then kind of. Clunks to a stop, then trying to start from there I can't get the starter to turn. Doest sounds to.o. Good huh?
 
Do you have a magneto or a distributor. You need battery voltage for a distributor. A magneto doesn't require battery voltage. Post a picture of what you have. Loosen the bolts on the starter and see if the bendix drive retracts.
It may be stuck in the ring gear on your flywheel. Find a friend that works on engines and get him to help you getting your tractor started. Hal
