I hope everyone had a great weekend. For the wife and I we did something we don't normally do, stayed home the entire weekend. We will usually either go to dinner or get take-out one night of the weekend and breakfast on Sunday is pretty much a given. However, with the winter snow warning for the entire weekend the wife just wanted to stay home and relax although she did promise me some kick-*** meals, so I was all in.
Friday night I started out by wheeling the snowblower out to the shop to work on it. It ran good for the first part of the previous storm but then mid-way through it started hunting again and wouldn't idle at all. I thought for certain I had more **** in the fuel bowl but once I got it removed the bowl was clean as could be.
I thought the smaller pilot circuit must be plugged with something from when the bowl had debris in it last week but after working on it for a bit the kids come by and I was anxious to see my grandson so I closed up shop and headed in the house.
Fortunately, we didn't get any snow Friday night but we were expecting 5-9 inches between Saturday afternoon and Sunday morning. The wife made me an awesome breakfast on Saturday and then she wanted to be left alone to do her housework. I took the hint and headed to the shop to pick up where I left off Friday night on the snowblower. I hate these damn tamperproof carburetors that are the norm these days. I realize they do it for EPA reasons, but they can be a PITA to work on. I finally got the pilot jet out and cleaned the pilot circuit thoroughly then she purred like a kitten again. I also took that time to replace the fuel filter under the fuel tank and removed the recoil starter housing to replace the fraying pull rope.
I used the last of the 5.5 size pull rope from my spool with about 16 inches to spare, so I had to order some more afterwards.
It is always better to replace these pull ropes before they break to prevent the spring from blowing apart inside the housing. I caught mine just in time as I don't think it was long for this life.
I clamped the pulley to the housing after pulling the rope out of the pulley, then cut the knots off to allow them to pull through the pulley and handle.
After a double knot on each end I melted the ends after cutting.....
and pulled the knots into the corresponding pockets.
I also added one more revolution to the spring as it felt a bit weak at the last couple of inches. Completed and ready to reinstall.
After reinstalling the recoil starter, I fired it up, checked, double checked and then triple checked that the machine would idle down and rev up to full throttle without hesitation or any hunting. Mission accomplished. I then thought I'd check the RPM and it was a little low. These are designed to run at 3600 RPM and mine was just over 3100 so I bumped it up to slightly over 3400 RPM.
I had originally figured that I would swap the modified skids out when the others wore through after all, I had just flipped the skids at the beginning of this season. However, my curiosity was getting the better of me and I had to see if they would work.
The problem revealed itself as a bit of a design oversight. When I cut the steel blocks last week and welded them to the worn side of each skid, I used a pocket rule for the height and kind of eyeballed it.
Well, when I went to install them I quickly realized that I hadn't allocated enough room for the nut nor a socket in which to tighten the nut. No worries, nothing a quick trip to the mill couldn't take care of.
I clamped the skid in the mill vise and found center of the 5/16" slotted hole and cut a recess approx. .200" deep.
I then grabbed a 1/2" socket and after measuring it, I grabbed a .750" diameter end mill and enlarged the recess to the .200" depth.
This will allow the nut to be installed and the socket to fit without removing so much material that it negates the thicker skid.
Cleaned and deburred. Ready for installation.
After placing the center scraper bar on a piece of cardboard, I installed the skids on either side of the auger chute and adjusted to light contact with the concrete. Tightened the carriage bolts down and it is now ready for snow.
These skids still have a good side so I bagged them up in the hopes that this mod will work for a long duration, then I'll perform the same modification to this set of skids.
Thanks for looking.
