Tractor will not start with use of starting fluid. Once started it will run, but not accelerate smoothly. It will not restart after being shut down without use of fluid. I have cleaned and installed carb kit. Gas tank is gravity flow and clean with a good supply of gas running down to carb. Float bowl fills. Can hand chock across carb intake and there is a lot of suckion. Compression in all cylinders is between 120-130#. Put new plugs in and hand chocked and tried to start. Nothing. Pulled plug and it was dry. Carb is an updraft Marvel. It seems there is just no gas getting into engine, even though there is gas in carb. All carb passages have had a cleaning wire run through them and then flushed with spray can of carb cleaner. I'm lost!

Thanks for all comments. Spark hot at all plugs, new coil. Carb has had a rebuild kit installer. Atomizer from main needle valve is new. Fuel intake screen is new. Points have been filed. 12v system, engine turns over strong. With engine at idle, sprayed WD-40 around every gasket and did not detect any leaks. Have not checked timing. I am still mystified as to why I cannot wet the plugs by hand chocking. I feel that I am not getting any gas into the engine.

When you cleaned the carb before rebuilding it, did you soak it overnight in a bucket of carb cleaner? It really needs to be supper clean and you can't do that with a spray can of carb cleaner.I repeat my question from my previous post. Did you make sure the pressure balance tube was clear? It's connected to one of the little holes exposed when you split the carburetor and is in the web area of the fuel bowl and the other end is in the air horn. Another way to see if that's your problem is to cut a piece out of the large carb gasket near the front of the fuel bowl. (This will vent the bowl, though not correctly.)If the engine starts, then that's your problem.

The other possibility is that your float setting is too low and you can't get fuel out of the carb through the metering jet. Usually the problem with these M-S carbs is that the float is set too high and the carb floods.

Another thing you can do is to sqirt some gas into the carb while you crank the engine over. If it starts, then you know the carb is the problem.

Hope this helps.

If you haven't done this, pull gas line from carb and check filter in elbow where the line goes into carb. If that is ok, open sediment valve and let gas run and see if it runs in strong stream for a minute or more (catch gas in good gas can). Not sure anyone mentioned, or if you mentioned, checking all the filters but this will provide that check.

If you have fuel in the float bowl and it seems like no fuel is getting to the cylinders, let me ask you this. In the carb air horn, there is a little hole near the choke that is the pressure balance tube for the carb. It vents the fuel bowl to the front of the carb, and since it is downstream of the air filter, makes the carb mixture ratio be insensitive to air cleaner restriction.( THis is called a carb with pressure balanced design.) If this tube is blocked, the it's hard for the metering jets to pull fuel out of the unvented fuel bowl. Find the hole and make sure that it is clear.It's a small drilled hole that internally connects to another passage that runs to a spot above the fuel bowl. Some people that have had this problem cut a notch out of the gasket to provide a vent and others drill a small hole in the top part of the casting over the fuel bowl. I recommend you don't do that but rather get the pressure balance tube clear.

The other comments about spark and timing are also true. In fact, I always recommend you check the spark FIRST, when you have a "no start" condition. If you have a fat, bluish spark, then check the timing statically. If the timing is correct then check the fuel delivery to the carb and if that's OK then suspect a problen with a dirty carb. I would estimate that 90% of the "no starts" are ignition system related, especially with 6V systems. Make the checks systematically and write the results down for further review and analysis. Change one thing at a time and record the results so you 'll know the root cause of your difficulty. If you change a bunch of stuff and get a start, you'll never learn the nuances of these old machines and you'll always spend more than you hvae to to correct a problem.

Hope this helps you.

Since the plug you pulled was dry (not sure how many you pulled), it does sound as if you are not getting fuel to the cylinders. But just for grins, have you checked the spark? Didn't see you mention that. Pull plug wire and ground, or hold almost to ground, using screwdriver, or better yet use one of the spark dongles that connect to the wire and to the plug and show the spark, if any. See if you have blue spark. If not, that might be first thing to check. If so, pull carb again and look at main jet, the one with many fine holes alternating around the sides. You have to pull it with 3/8 deep socket. Those holes get clogged, and because it is not easy to pull without proper socket, sometimes people leave it. Squirt carb cleaner into it and make sure it comes out of all the holes. Hope that helps.

what are your setting on the carburator? I'd start with idle mixture(small one) at 1 full turn out and Main (large one) at 1 or 1 1/4 full turn out. Next, I'd check for a good spark at coil, if good, check at individual plug wire end.
Does she turn over strong? 12 v or 6 V.?
I'd check the time screen inside of the carb (where fuel line enter carb) possibly blocked?
Are manifold to engine and manifold to carb. gaskets and bolts good and tight?
I'd also take a peak at points-make sure they are clean and filed. Also timing. I had a 6v'er get off timing and would start super difficult and then would NOT start after warm.
I'm sure I missed a bunch--but the next guys will help us both out. Good Luck, Mark
