Champion 3000 Watt Generator, Hard Starting when Cold - Page 7

 It WILL be easier to start - but only marginally. Won't make the
difference the OP is experiencing.  Won't make any more difference
than the leaning effect of using E10 gasoline instead of pure gas.

Now, using summer rated E10 will affect starting more than using E10
winter or pure summer gas. I suspect the carb is too lean for E10 to
start properly, and he may have a slow initial fill on the carb float
bowl too.

 
   I have learned that the winter blend of gasoline has a different RVP (Reid
Vapor Pressure) compared to summer.  The Winter blend has a higher evaporation
rate.

   Since I filled the generator's gas tank with the summer blend,  it's
evaporation rate is lower.  Perhaps this is why after several pulls on the
recoil starter,  when I wait a few minutes, then the generator starts.

     CONCLUSION:

   The fumes that form in the combustion chamber take more time to occur due
to the slower evaporation rate of the summer blend gasoline,  in addition to
the cold temperature (cold reduces evaporation rate).

  Be sure to let us all know  -  your results  -  
- when you have tested it with the winter gasoline.

Hi John T.

    I don't think I am going to bother going through the trouble
of draining the gas tank (summer blend gas), which is over half full.
Note: It isn't easy removing the hose from the fuel filter in order to drain
the tank.  I am not going to run the generator again until milder
weather (coming soon).

     I have learned from everyone's responses.  I have a better
understanding of why it is hard to start when cold.  If I actually need (power
outage) to use the generator when it is very cold,  I am prepared.  

   Once again,  Thanks to everyone for your tips,  John

I wanna Add;

1) Gas is Oxygenated (they call it), with Alcohol
   So, I say the Gas we get is only good for a month and couple of months y
our  
   pushing it. So, fresh Gas always starts way Better!

2) Try an old Propane torch unlit (Don't lite it), take the defuser off the
  
   Propane torch end, put the torch end directly in the carburetor as far i
n as  
   you can and open the valve wide open (Two Cycle Diesel Starting Trick),  
turn  
   the Torch off when you see icing on the torch end and immediately pull
  
   start.  
   Should start no problem first pull☺
    
   Forget the Starting fluid and this won't work on your car because, the  
  
   Propane torch won't give enough fuel (The Car engine is too Big)

3) Water collects at the Bottom of any fuel Tank during the Cold Winter.
   Especially since Alcohol has been induced into our Gas.
   The Water in the Service Station Tank(s) ends up in your Tank
   Cause, Alcohol makes Water molecules adhere to the Gas and run right thr
ough  
   the Station's filters and we just got rid of all their water and paid em
!  
   Cars Also have Fuel filters which get most of the water but Alcohol make
s  
   Water molecules adhere to the Gas and the Rest just gets ran  
   through the engine, with a little hard starting, sputter and a miss  
you don't even notice.
