Need help identifying a Command Eng
 

Hi all. I purchased a 1863 parts tractor that had a ch18s engine with a thrown rod. The deal also included a 2nd Command engine that had no blower housing to identify it. I took several photos of it and hope someone can tell me what HP engine it is. I was told it's a 25 HP. The engine had the ignition wires cut from what appears to be some sort of ignition module that I think went to 2- 2 terminal spark coils. I was reading on another thread about a ch25 having an ignition module. It has a 1 1/8" shaft but it's 3 1/4" long. The ch18 had a shaft length of 2 5/8".

Please see the attached photos.


The carburetor also has a accelerator pump on it as well.

Thanks!

I have been trying to get this unknown command engine to run. I took the spark coils off of the ch18 and put them on this engine. I also used the flywheel from the ch18 as well. I disassembled the carb and cleaned all the crud out of it. I used the blower housing from the 18 as well. When I first tried to start it, it would run briefly on carb cleaner. I had to wait a couple of days for a dipstick to arrive so the pulse fuel pump would work and get gas to the carb.


Today when I tried to start it, all it would do is backfire through both the exhaust and carb. It has a good spark and has 175 psi on one cylinder and 155 psi on the 2nd. I'm thinking I have a timing issue.


Can I use the spark coils and flywheel off the ch18 hp on this engine? Why did it run the other day and not today. I did have the anti backfire solenoid energized and on.


Thanks

I have a GT 3200 that has a 25 hp command and the carb does not have an accelerator pump, but I also have a 3225 with a 22 hp command that does have an accelerator pump on it. Bought both used but believe both have original engines. I see from the photos your are also missing the charging stator.

I used the stator and voltage reg. from the ch18.


I have a 3240 with a 22hp command. I'll have to look at it and see if it has the same carb with the accelerator pump on it. I know it doesn't have the large dipstick though.


Thanks!

Looked at pics again and agree that is a larger dip stick tube than what came on the 3200 series command engines.

If anyone is interested, I got the engine running today. My timing problem was caused by a sheared woodruff key because I did not tighten the flywheel bolt tight enough. My bad!

Engine runs really good. Very pleased.

Did you happen to figure out how many horsepower the command is?

No I did not.
