BG86-C issues

[95custmz]

I had similar problems with my blower. It ran a little rich, therefore, I was cleaning the muffler once a year. But once I did the muffler mod, adjusted carb, and changed the spark plug I have not had problems with it. I believe the correct spark plug for yours is NGK CMR6H or the equivalent.

Sounds rich to me but I am on a tablet with cheap built in speakers. I would pressure and vacuum test, if it were me to make sure there isn't a leak. Optional, if you want to. But that is the only reason I could think of for the high speed changing. Unless, you haven't rebuilt or cleaned the carb yet. If you haven't, I would definitely open the carb and clean it with spray carb cleaner.

Also, how old is the fuel you are putting in it?

I do need to at least clean the carb. I was considering the 16$ eBay carb to just replace it. The muffler is pretty bad shape should I change it or will it make a difference? I'm using trufuel and it's not very old.

What kind of muffler mod did you do? Mine is all rusted up from who know what the person before me did

A lot of muffler rust because there aren't stain less steel. Just rip the cat out or punch a hole in it. I bought one of those ebay chinese carbs for my EB802 but I am not terrible impressed with it. It does work but the internal screen was not placed properly in the carb body, which would have allowed dirt into the carb. Also, a lot of flash internal. Which could break of, maybe, and create a big problem. I cleaned the factory carb, bought the small d tool and am putting it back on. The gaskets and diaphrams were good.

Alright I'll stick with original carb and just clean it real well. I may play around with the muffler and open it up a slight bit for giggles

I soaked the whole muffler in carb cleaner overnight to clean off carbon build up. I removed baffle and opened up the muffler opening at the cylinder exhaust port with a router bit to let the engine breathe better. You will need to adjust the carb as the air/fuel ratio will change once you do the mod.

Great I'll try that out on my next days off. Worst thing would be I have to buy another muffler if I screw it up somehow .

Let us know how it works out.

 

[LonestarStihl]

I will for sure. I'm kinda having fun with it. It'll still blow alright right now. But it's not running well and I can tell it's not putting out all it's got

You'll be amazed at what a muff mod will do. The EPA has such strict regulations these days. With a little bit of tinkering, you can get your chainsaw, blower, motorcycle, etc. to run extremely better with a better flowing air filter (K&N), muff mod, carb adj., timing, etc.

Yeh I found the tool to take the limiter caps off on eBay. I haven't become that intense yet but I'm sure I'll get there

Just wait till backhoelover gets ahold of you. I have never seen so many carb tools in my life!
