Just went outside to take pics of the fleet, and I decided to attempt to cold start the roper rt16 in moto mower clothes and the moto mower 6020 (repowered with a 6.5 Briggs clone) just for fun.

Usually the moto mower is a quick starter, just some choke and away, not the case today.

The roper, I picked up this fall, and haven't had much time to even think about it. It rolled over slowly...

Any suggestions to make for easier starting? I'm sure all members could benefit from this thread...

Try to channel hot/warm air to the carb. In winter I often use a hot air gun for starting the JD 3120.

If you have 30W oil, get some heat on them.

Depends on why its hard starting. Sometimes when its cold the engine gets hard to turn over, thats most likely the oil your using or a battery. If its cranking and cranking until it starts and thats your hard starting issue then try and richen up your mixture settings and make sure your able to get full choke, I have seem some choke cables not adjusted right cause a 3/4 choke issue and that can make it hard to get enough fuel on the cold days to get it going.

It's a slow to turn over cold start, I do think it's because of the cold oil...

I always give things a quick squirt of carb cleaner to insure a no fuss start when it's cold.

I had some of that cheap Wallmart Hi-Tec non detergent 30 wt in my snow blower.Temps dropped to around 20F and it would Not crank over even with the 110v electric starter.Pulled the dipstick and the oil was so thick I could hardly pull the dipstick out of the darn thing.Oil jelled up to the consistency of cold roofing tar.

 

I had to bring it in the house for a few hours till it warmed up enough to get it to crank over. After starting it I let it warm up for 10-15 minutes and shut it off and drained the oil and put some good part synthetic10w 30 in it. The Hi Mileage Castrol in the Green jug is part synthetic and doesn't get as thick as conventional oil in cold temps. I would of put good 15w 40 full synthetic in it if it wasn't $9 a quart.

 

Still a little stiff to crank over when it's really cold with the recoil starter but it's ALOT better.

 

I've been having alot of problems with Ethanol Gas jelling up in small engine float bowls.The water separates from the ethanol in the float bowls and makes a sticky gelatin like substance that clogs jets.Might have to try a bit of gas line antifreeze and a little 2 stroke oil in my blower gas.

A little heat on the block or oil filter helps. In low temps I set a halogen light next to it for about half an hour. Seems to help some.

with the wind chill you are likely about -30F today. Magnetic block heater would be the easiest if you have no warm indoor shop. Plug in for a hour and should be good. We are in a current cold spell so be careful you don't ruin your starter just to see how it starts... Tiger Torch directing hot air at engine block for 15 minutes would also make it easy to start,,you could even use a small propane torch with piece of tubing to direct heat. Don't put flame on engine for obvious reason,,,don't want to cook the paint..

I've used the propane torch to help start  engines. I don' t light the torch. Hold it so it blows propane gas into the carb. This feeds vaporized gas directly into the engine and if there is spark it will fire. Don't stand directly in front of the carb throat in case you get a back fire. It has never happened to me but back fires do happen.

I used to use a dipstick oil heater in a CC 1650 that hated starting in the cold.  It worked well.  

 

The Kat's model says to use it in 4" of oil.  Mine wasn't a Kat's.  I never checked how far it went in the oil.  I never had a problem with it.

  Uh, jazz, windchill only affects living things. If the wind is blowing on something warm and mechanical it will cool off faster but will be no colder than the ambient temperature.

As stated above windchill only affects living things

Easy way is to tarp tractor and place a electric heater under tarp to warm engine up before starting

Also a good battery will help, small automotive battery best, small lawn and garden battery is ok for summer but not the winter

The more cold cranking amps the better for us up here in the Great White North

You can buy a magnetic heater that will stick to the block, put it on and plug it in about a half hour before you need to start.
