Update on the 123: Still no progress!

[cubby123]

Well, I have worked a lil more on the cub daily and she just won't go. I am pretty sure that it's a carb issue and electrical because when I put gas in the carb she wont fire but will puff out white smoke. I am completely stumped if that's not it.

Hey cubby! I read thru your other post on your issues. Have you checked that float yet?? If you have fuel freely flowing thru the carb (as you stated in your other post) there is a problem in your carb. (float, stuck needle valve?) Also, your last post in your original thread says that it sounds like the engine is running while your turning it over, but won't continue when you let off the key. That could be a timing issue or a stuck valve issue?

Check out that carb & float! Check your compression (borrow if you don't have one). I'm a bit analytical and will sometimes bury myself in the details, you know, miss the forest because of the trees! I was having trouble getting my Chevelle tuned and a buddy told me, "It's only a gasoline engine. You have fuel delivery, spark, and timing. What's so hard?"

Good luck and give us some details on what you've been doing.

White smoke is good... It means that you're on the right track.

If it were mine I would take the high speed needle out of the carb, make sure the holes in it and the passage through the middle of it are clear, then put it back in.

If your plug is getting wet you're getting too much gas, so just to make it run, try turning the needle "in".

From what you say, If you're getting fire to the plug, I'm really thinking that you're a little out of time.

98% of all carburetor problems are electrical.

Sam, I couldn't agree more.

If it won't even fire when you squirt gas into the carb, it's not a carb problem. The tractor should catch and run for half a second and then die if you squirt gas in the carb. It sounds like you either have crappy spark, low compression, or the timing's way off. It doesn't take too much of a timing variation to make these things difficult to start.

Ok,I willtry timing it. Whe you say timing do you mean timing the points? I'm still learning these "phrases" LOL. I can be a lil slow.

Dude, you've got an ignition problem.
Take the carb off.....have someone crank it over, and give it a light squirt of ether, direct in to the intake port.
If you're ignition is working at all, it'll fire.
Try yanking the motor, and bolting it down to a bench with lagbolts, through a 2x4 on each side to give the oil pan room.
That way, you can check everything much easier.
Just use jumper cables to a battery.

Well I took the engine apart again after i replaced the rod I never got it honed or got new rings so I am going to get it honed for free from a guy I know I just gotta buy new rings and also I gotta buy new gaskets for all around. After I put it back together I will set it up on the bench and try it out

Also I found out the relief valve is rusted shut so there's another thing I gotta do but she should be ready to plow snow by winter.
