snowblower primer problem ?

6 posts in this topic

i have snowblower with a rubber push type primer. you know, push the primer 3-4 times, pull the rope and snowblower starts. the last 2 times i tried to start my s.b. the primer would not push/pump---it felt like it was plugged or somethimg as when i tried to push it, it was just tight (?) felt like nothing was releasing out of the back side. it was like pushing on a balloon or tennis ball. i got out my little propane heater and directed heat towards s.b. for 4-5 minutes and then i could push primer and hear/feel gas going out and snowblower starts. after i blow snow, i check primer and it works. after it sits in attached garage overnite, it acts like its plugged or froze shut until i warm it up with heat. it is older s.b. but has always run with out problem. any advice as to why the primer will not work or what i can do to make sure it works when i need it.

Water in the gas line is what comes to my mind. Could try running heet in the gas for a tank or so and see if it helps.

Roop I have to agree with upnorth that it sounds like water in the line unless you have been able to run a tank of gas through the tank since the problem started. It you have maybe open the gas cap when you are done just to see if it is some how creating a vacuum. It might be time to run some tune up in a can grin

its not a gas cap vacuum problem--checked that already. did think of water but thought w/ 10% ethanal i wouldn't have a water problem.

i will try to run some kind of cleaner thru it.

also, sometimes when primer has been pushed in, it will not readily expand again. it comes out very slow or if i massage it, it will slowly come back. thank you for your replys

My old Simplicity was lousy right from the get go but thank goodness it was never really needed. I have a Ariens at the cabin and the bulb works great.

On the side of the carburator there is a small vent hole for the float bowl. The vent hole gets plugged with ice, dust, whatever, and it can cause a whole bunch of issues. You are experiencing one of those. Another common one it causes is the carb freezes up and will not run without the choke on. Nasty little deal! Your heater (?!) in the vicinity happened to get enough heat in the area to thaw it out. I guess I would suggest that you spray off the outside of your carb with the sheild off, find the hole, and clean it out. I would caution against having any heat source that close to gasoline. Especially a propane heater. Please be safe.

    • I hunt zone 1.  Very interesting to see those numbers.  From what I have seen the herd is showing signs of rebound in our neighborhood.  We're a ways off from being able to tolerate hunters choice, but we're seeing deer again finally.  I agree the herd is in better shape than 2-3 years ago when many people saw no deer and no signs of deer.     So what does it all mean?  I suspect the widespread pain of the glut in major swaths of zone 1 for the dark years has woke some up to the idea of passing does.  There was certainly more opportunity with fewer bucks-only zones and larger doe tag numbers in certain DPAs.    What will be interesting is how the DNR responds to more deer on the landscape up here but fewer does being shot.  We had two doe tags in our group this year and we proudly tossed them in the fire, unfilled, at the end of season.

    • I have this problem from time to time but not often.  Sometimes there are little bubbles on the bottom of the transducer and sometimes the ducer isn't below the ice, sometimes it just takes 5 or 10 minutes of sitting in the hole before it starts to pick up the jig.  Other times it works flawlessly.

    • I hate to break your bubble, but your vote and other Trump voters in Minnesota were wasted votes the same as you say those who voted 3rd party were wasted.
