We need lots more information. What do you mean by "hit"? Exactly what have you tried, and exactly what happened?

Hit as it run like 2sec. I have adjusted the distributor some and it dont change any thing. I have have adjusted the carb some. I have checked the spark and it is has a very strong blue arc across the plugs.

First pull out the front plug, run that piston up to the top (TDC) on compression. Then pull off your distributor cap and point cover. See if the points have just opened.
If they have, turn the engine back about 5 degrees and hold the coil wire close to a good ground. Then rotate the rotor back and forth, breaking and closing the points. See if you're getting a good blue spark. It should jump about a half and inch.
If you have all that, you have a fuel/carb problem

sounds like a gas issue to me. make sure carb bowl is full of gas and that the float opens had this happen made me crazy till I discovered that the float was't opening!!!!

The carb has been rebuilt two time throught this site! The only thing thing that i have not replaced that I know may be it it the intake. But I have sprayed starting luid around the intake and it does not act as if it has a crack in it.

Do you by chance mean that it starts but as soon as you let off of start button it dies?
Does the tractor have a resistor in the coil circuit with a wire from coil end to start solenoid? (12 Volt coil "External Resistor Required")
If so your resistor is probably open. The resistor reduces 12 Volts to 6 Volts at coil. When start solenoid is activated it applies 12 volts to coil for hotter starting spark. When you start it goes on 12 volts, but let off starter and defective resistor is not supplying run current to the coil.

Sounds like it's choking out. Have you checked the air inlet all the way from the air cleaner to the carb? Might be plugged somewere.

I dont have the air cleaner hooked up and the resistor has 11.8 volts on both sides.

If it is hooked into the distributor, and the points are closed, it should read in the 6 to 8 volt area. But if the points are open, or it is disconnected from the wire, it will read pretty close to the same on both ends. A bad resistor will heat and open up in the short time it is "running" but I would think it would show a no spark when static tested as well. I would just bypass it for a trial to see if it is the cause. Just thinking out loud. JimN

Had that happen on my 450. Drove me nuts till I found a broken wire.

was the tractor running before the tune up or did it break down and you are trying to get it going? as it has a lot of new parts in it, i;d do some background checking before throwing more parts at it. with the air cleaner off, give er a shot of ether and see if she starts. if so, look to a fuel problem, does the carb flood some with the choke on? if so look to ignition.
at this point i would run a jumper wire from the battery + to the coil + if 12v neg ground, effectively bypassing the starting and ignition switch "hot wiring" use an alligator clip so you can disconnect the wire if it starts. see if it will start and run with the hot wire.
pull a plug and check for spark when cranking it over. if you have good spark, squirt a couple pumps of motor oil in each cylinder, crank the engine a couple of times to spread the oil around, then replace the plugs, give er a shot of ether and see if it starts. the oil will help raise the compression if the rings are dry.

i just got my 130 running after sitting for 10 years carb was stopped up rebuilt cranking would pop but never start even tried cranking manually nothing towed in 4th 100 yds fired up runs great,think was not cranking fast enough to draw gas or was drawing too much from elec system.
Do use the choke. Try starting fluid. Do pull it off using another tractor with yours in high and the pulling tractor in low. Sometimes these gasoline engines can be hard to start the first time after a long set up and or major parts rebuild/replacement. Do these things only after you are certain you have spark to the plugs.
You need to pull off a plug wire and have someone make an attempt to start the engine. Hold the plug wire 1/4" away from a good ground or the plug to see if you're getting fire to the plugs.
If you're not getting a hot spark to the plugs run some 320 wet or dry through the new points. Make sure your plug wires are in the correct firing order on the cap. Should be 1-5-3-6-2-4 Hal
