Correct Piston..Finally!

Thanks guys! I’ll look into it as time permits

Got everything put back together and went to see if the engine would at least turn over. When I tried to hook up the battery it sparked so bad I couldn’t even hook up the second terminal. I’ve never had that happen before. Double checked my wiring connections, everything seemed correct and tight.

The only thing is I put on a new key switch that is a 5 prong instead of a 4. Is it possible that’s the cause?

The switch you have is for a magneto coil ignition and with key off goes to ground to kill the ignition .
There are as many different configurations in 4/5/7 blade as there is makes and models of tractors out there , but they all look the same on the outside. One of the dealers I am sure can help you out getting the right one for your tractor .

Alright… put the old key switch back in and it works. Now we’re back to engine turning like a cyclone but it won’t fire, even with starting fluid. Has spark. Correct pistons this time…

One of the most problematic parts is the condenser. I've seen them work then out of the blue they don't. I've even put in an old one and they fire right up. That's why it's always easier to have it mounted on the coil. The last few I've replaced I put on a transdenser from Dave Kirk http://kirkengines.com and have no problem at all. Just my observation Vivala.

Would it be possible that it was damaged when the engine was Eli g moved around during the rebuild? I was as gentle as I could be but without a proper work bench it could have still gotten k Ickes around a good bit

When you put it back together, were you careful about the timing? To start, the engine needs:
1. Compression
2. Air/gas vapour mix
3. Spark at the right time

No 2 can be ruled out because of the starting fluid.

You can easily check for spark by pulling the spark plug out and touch it's sleeve to a metal part of the engine so it gets good ground, then crank the engine. You should see a healthy spark on both plugs.

So that leaves two things out: compression and timing. If the spark plug doesn't spark at the right time you get no detonation. Same if you don't have compression. If you don't have a compression gauge, you can do the "thumb compression test." Pull the spark plug out and press your thumb hard on the spark plug hole; open throttle to max and crank engine. It should easily push your thumb away. If not, or if it feels weak, your got no compression on that cylinder.

As for timing, hopefully you used the service manual for your engine to make sure timing is correct, when you assembled engine again.

When you say "turning like a cyclone " I assume you mean fast and free.
I assume that you did not remove the cam shaft, crank or points . If so, timing should not be an issue .
Did you use some oil in the cylinder and on rings during assembly ?
Did you make sure ring grooves were clean and ring don't stick in the grooves when when squeezed in with ring compressor ?
Did you check heads for flat? repeated on and off of heads can warp them if not done properly .
Did you check for compression , or leak down test after reassembling and before tins went back on ?

Sorry about all the questions , but not watching you put it together just trying to get a clearer picture .

Anything is possible but I feel you missed a step in assembly . Answer the question I left you and that will give us a clear picture .

The only thing I haven’t done is check for compression
