I loaded up my Bolens 850 and Trac-Vac on my "new" (to me) trailer yesterday to head over to do some leaf pickup. However, it took longer than I anticipated, so I loaded everything back up and hauled it back to my house last night. I left the tractor on the trailer overnight so I could head out first thing in the morning today to finish the job. However, when I hauled my setup back over to his house today to finish the job, for some reason the old Bolens wouldn't start! It was very frustrating since I JUST had it running all day yesterday with no problems. Granted, it was a bit colder out today than it was yesterday, but not by much. It struggled to get in the 30's today and most of the day it was around 27 degrees out whereas yesterday it got to a high of around 35 degrees.
But in any event, I pulled the throttle out about 1/3 and had the choke on full to try and start it. At first, it tried to fire right up and started running very slowly with the choke on. I pushed the choke in halfway as it was trying to run and it continued on for about 10 seconds or so until it finally died. I tried cranking it with half choke for a bit and it didn't sound like it wanted to do anything. So, I pulled the choke out all the way again and tried cranking it over and it sputtered for a bit and tried to start again, but it ran for about 10-15 seconds on half choke again and it sounded like it was dying again, so I pulled the choke out all the way again for a sec and then tried pushing it in and the engine just didn't want to run, so it died on me again. When I went to crank it over again, I couldn't get anything out of it at all. I was cranking it over for a good 20 minutes (off and on again of course and I never cranked it for longer than 15-20 seconds at a time). I tried full choke, half choke, and no choke and nothing seemed to make a difference. I finally gave up and did some trim work with my push mower (which I thankfully brought over) and did what I could for today and then left to go back home.
But, here is the strangest part of all. After I get back home and start to unload the trailer, I figure I'll try starting the Bolens 850 one last time as I didn't want to have to push it off the trailer by hand. I cranked it over a bit and still nothing, it didn't even sound like it wanted to start. So, I grabbed a can of carb cleaner spray to try spraying in the intake just to see if that would make any difference. A little spritz of carb cleaner later and with the choke on full, it started right up no problem! I let it idle for a few minutes and drove it right off the trailer. So why the heck didn't it want to run earlier? Was the carb flooded perhaps from choking it too long or something? Is there maybe an issue with my fuel line where it's not quite getting enough gas to start it when it is so cold out? I never had any issues with it starting when it was warmer out over the summer. Any other ideas? I just want to be sure this isn't going to be an ongoing problem as winter approaches and I want to use it to plough driveways with.
