Thanks! I will give this a shot and see how it goes.

I just got one from my dealership for a reasonable price

Hey there, I did a bit of maintenance on my BG 86 a couple days ago. It's been running a fair amount lately for snow removal purposes and I didn't get a chance to do fall maintenance. Cleaned out the carb (ultrasonic cleaner), cleaned/burned off spark plug (a little black) and checked gap...

I am curious if it may cause an off-balance in force in the flywheel and cause it to spin slower or faster than spec which may cause extra wear on particular parts. But just a theory. =)

Looks like the engine number is 5X65MU

Okay, looks like it wasn't anything major. I cleaned the original carburetor again with a wire, carb cleaner, and compressed air and that seemed to do the trick. The mower is running again. So the culprit was a clogged carb, clogged gas cap, and non-functional ignition coil. One interesting...

The last spark plug had black carbon build-up on it, if that info is useful. Will check engine number

Yeah, I have taken the fuel filter out a couple times wiped it off and blown it out. Not sure if it has some sort of clogging on the screen but fuel does run through it so I don't think it's an issue.

Yeah, it's in tank. I didn't use carb cleaner but used air on it. It's a plastic filter you think using carb cleaner is a good idea? It was replaced spring of this year.

So I am trying to get my 159cc Columbia (MTD built) mower to run but have been having problems diagnosing the issue. The mower starts but then bogs down and cuts out. Usually within seconds of starting if not right away. Once out of several test starts it ran maybe 4 seconds then choked up and...

Thanks for reply! I don't think it's worth repair with so many variables in what the problem could be in the engine versus time and parts cost. When I tried turning the engine over gas would simply leak through the system into the muffler. Same issue with a new carb.

Well, the blower has spark and the fuel system is now pretty good (changed fuel lines, tested tank pressure, changed carb, changed fuel filter) but... there is no compression whatsoever. I thought I was going to give up on this machine before... Haha! Maybe now is the time? At least I'm...

Thanks for the advice. I tried it out. Don't know how I missed this but the carb is not the only problem (but was one of them)... Oh, boy.

The machine is back to its old habits. Despite increasing the idle speed slightly (which did make a difference in how it ran overall) it will still have trouble revving back up after 15-20 minutes use once I idle it. It either cuts out in idle or bogs down when throttled up and then cuts out...

I cleaned this out about 2 months ago and haven't been running it as heavily in the summer. Might be worth burning the muffler out and re-cleaning the spark arrestor screen before heavier usage begins come summer.

So I opened up the machine and looked into the lines and connections and didn't find anything unusual. Wasn't quite sure if I was interpreting your explanation correctly so I have attached some photos for clarification. The one photo shows the carb with top and bottom attachment points. The...

Yes, installed a new kit on the carb. From my research one should set the lever flush with carburetor surface so I did that. However, I did not follow any specs specifically for this machine regarding that setting. So you are saying the idle speed should be slightly increased to run richer...

Yes, the unit has a remote primer. Could be the cause. Will look into it tomorrow and let you know the results.

Hi there, More issues with this unit. Trying to learn to fix things on this equipment as I go. Any help or advice would be appreciated. Well after rebuilding the carb, tuning it, and installing a new spark plug I am having a new issue: the unit seems to run fine after warming it up. I put it...

Thanks for advice on carb adjustments. I don't think that was the issue. Once I changed the spark plug things ran a lot better. I adjusted the carb appropriately and it runs decent. My concern, however, is that the last spark plug was oil fouled so there must be an underlying problem. Would...

Hi there, I am trying to figure out what is going wrong with my 125b leaf blower. Any advice would be appreciated. I was running it fine on Husqvarna 50:1 mix (I just mix the small bottle with 5 l gas as recommended) with premium fuel (stabilizer added to can right on pumping) and then I added...
