Two Stage Snowblower Issue

610 158 December 25, 2017 at 05:02 PM
The issuse I'm having is that every year I have to swap out the spark plug or it will not start. This particular season i have replaced the spark plug twice within a 1 1\2 - 2 week span. Suggestions on what is causing this?

Wrong gap or fuel too rich or oil leaking into cylinder?

if you still have a spark plug please post a picture.
Before every season, I use wirebrush to clean spark plug(s).
At this point, I am using 10+ years oem spark plugs on my power toys.

Here's a picture of the used spark that was installed about 2 weeks ago. The gap size is correct. I don't if you can tell from the image the spark is completely blackened.

I assume this is a four stroke engine. Have you tuned the Carburetor at all? Is it using oil?

How old is the snowblower?
I had issues with a snowblower where I had to clean the carb regularly and the thing would never start easily, idle properly and most importantly didn't have much power. I got tired of stripping the carb down so I did some reading - found out that the carbs are junk and put a new one on for about $14. Starts, idles and runs like a champ. That was a couple of years ago and zero problems since. It's like a new machine only it is better than it was when new.

it's about 5+ years old....I just went ahead and ordered a new carb, but I will probably keep the old one & clean it up just incase.

Appreciate everyone's help with this matter.Applause

you can buy {you model here} carburetor rebuild kit.
also your carburetor may need to be adjusted

Rebuild kit on these is a mistake / waste of time and why on earth would you put the time into something that's replaceable (with a better unit) for about $14?
The whole problem with a lot of the originals is that they are junk - heck, many are plastic! Mine had been stripped, cleaned and adjusted several times. Waste of time.

depends on make / model and skills
in some cases, you just need to put a new diaphragm similar to this one https://www.ebay.com/p/Tecumseh-C...2688776472

you can change it without removing carburetor from engine.

if you are replacing carburetor you also need to have a new gasket, since old one will crack and / or may not have proper seal.

Most of the carbs come with replacement gaskets at least mine did. The carbs that I'm calling junk wear out. You can't fix a wobbly shaft with a rebuild kit. You can't fix a design fault with a rebuild kit. Nobody in their right mind rebuilds junk.
