Cold Start

[Gary S.]

For the last 40+ years ours has always started hard when cold and when cold I mean 15 degrees F and below. I run 10w in it and hook up the battery charger about 1/2 hour before using. Our loboy which is only used for mowing, starts hard when it in the 40's and only then when the throttle is all the way back. I think it's something to do with the Zenith carb or that it's smarter than me and dosen't want to go out!

Well after the tune up I still had trouble starting the tractor. I thought I flooded the tractor so I removed the air intake to the carb to let the gas evaporate. While I had it open I operated the choke from the pull only to find out it was not operating the choke. I manually fliiped over the choke and it started great. I think this has been the root of my cold weather startup problem. I did get the tuneup done that I have been wanting to do as a result.

Sounds like you're on the right track!

I have had the same problem over the years with sevrial cubs. I found that they all ran well in warm weather but in cold weather it was a lot different. The problem was low compression. The compression in a good cub engine should be around 120 to 135 lbs when cranking with the starter. In the engines i had that were hard starting the compression was 80 lbs in all cylinders. The higher the compression the quicker the starts in cold weather. I some cases the engine needed a valve jb. in others it was a complete overhaul.
