Coil is new as well. Was replacing everything on this at one point and just stopped because life happened and I didn't have time to deal with it.

martyrant:

I lost count of the number of time people suggested cleaning the carb (fuel system). I suggest you listen.

Stop saying this engine was rebuilt. Replacing an oil pan and gasket is not a rebuild. Unless you can find proof, or remember what was done, you need to quit saying it was rebuilt. Honestly, I don't know how you could not remember if a motor was just repaired or overhauled. Quite a difference in price. If you didn't pay $700 to $1000 it didn't get overhauled, it got repaired.

I watched your video. Your quite the fool. You held that governor nearly at WOT. Are you trying to blow up your engine??? The engine is governed, and it is only designed to run up to at 3600 RPM. After that, you have to replace key parts to make it run faster. You revved it far over 4000 RPM. Your lucky it didn't fly apart. Keep your dang finger off the throttle unless you know what your doing, or unless you want to see what shrapnel from a cast iron flywheel feels like stuck in your leg. Good grief. :bash2: :bash2:


You really just need to do some fuel system cleaning and general maintenance to this thing. Go ask your neighbor to help. Use the service manual. Disassemble and clean the carb AND fuel tank. Replace the fuel line, install fresh gas. Reset the governor, adjust the valves. Replace the spark plug and the plug wire. Tune the carb to run on the motor after installation, not just to "factory specs". The screw positions the book suggests are just for a starting point. The book states that. Set the timing and clean the points. Don't gap them, set the timing. The books tells you how. If your neighbor is a good mechanic, he should know all that though. I think you definitely need some assistance in fixing this.

Go do all that and post back. You've had more than enough "help" to get starting doing something.




twoton:

Do you know how to explain anything on your own? Or do you have to post a link to other sites and other threads to accomplish every explanation you give? Why don't you try actually explaining something without using someone else's information. On another note, you used a cubfaq link to explain how to set and adjust the governor, yet DelaCub gave a link to the Kohler manual AND the OP said he downloaded it! Why not give him a page number or reference the service manual instead of another site? The manual should be the first place anyone looks for information.


Hey J Mech, good to see you around still. I did pay $700 and I'm fairly certain it was rebuilt, but like I said, I didn't do it, I wasn't standing there watching the guy, and it was done by a reputable small engine repair shop run by one man who is still in business. I'm sure if I cared enough to go bother him he'd remember what he did, but it's been several years and I figure at this point it's my problem and not his. Sorry saying it was rebuilt seems to have rubbed a few people the wrong way.

I did admit I'm not the best with this, so yes, I can be a fool at times and after reading through the manual I did notice that it was governed at 3600 and it was a bad idea.

Pulled the carb today and it looked like it was done when the engine was as far as I can tell, there was no gunk build up, seals looked new... Little gunk in the bottom, but it's the least I've ever seen pulling carbs (granted I've pulled like 4-5 and remember, I am a fool when it comes to this stuff). I did notice when I pulled it that the main needle wasn't set where it really should have been (I didn't bottom it out apparently, didn't want to break it after reading the manual).

Anyways, can see where this has gone, thanks to everyone who helped so far--I'll figure it out on my own from here.

I don't know if it's been mentioned or not but I would pull the gas tank and flush it real good. Pull the petcock out of the bottom of the tank and make sure the screen is not plugged up with crud. I had a similar issue with my 149 but the screen was torn and the top of the petcock valve was plugged full of debris. Just another place to look because it sounds like a fuel issue to me as well. One other thing as well is to make sure there is no gasket remnants stuck on the carb or the mounting face of the engine. That will cause issues as well. BTDT :bigthink:

Anyone going to actually tell this guy something he needs to do to try and fix it? Or is everyone just going to post links and their wild guesses?

Why don't you guys give him a list of things to do to diagnose, or fix it.....

There was not a darn thing wrong with my post, Jon. You seem to take the fun from the forum time and time again. Actually, my first post was a lot more helpful then your first post. I surly can tell you that I don't have the time you have to sit and try to help everyone out. My first post suggests a carb issue, and lo-and behold, we're on to that. Don't underestimate me.

That's a good one to remember.:beerchug:

Ok..... but in post #8 DeltaCub posted a link to the Kohler manual from the Kohler website, and the OP had already downloaded it. Why do you need to link to it again? Did you read the thread before posting?

J-Mech 06-06-2017 07:36 PM

You know what.... I'm just going to apologize to all. I was in a bad mood the other day. Lack of sleep I guess. I'm not making any excuses, just stating facts. Something about this thread rubbed me the wrong way, and I should have just passed on it. So, I'm sorry I jumped on you guys. You were all just trying to help. :beerchug:

twoton 06-06-2017 09:15 PM

You know, I was just worried that I had offended Ms DeltaCub by jumping in on the conversation.

So if I did, I'm sorry. You were doing a great job.:beerchug:
