55 husqvarna not starting when hot
DIR By: 55huskyowner

I have owned Husqvarna for many years. I have a 55 chainsaw that
I cut wood with and a 55 rancher my son uses. I also have a
straight shaft Husqvarna weed eater. I am having trouble with
all three of these starting when they are hot. I have never had
this trouble. The funny thing is all three just started this at
the same time. So today I bought 93 octane with synthetic
husqvarna oil mix. They are doing the same thing with the new
gas. Could it be the synthetic oil causing the problem??

IMO no.
Do you guys have winter blend gas in pumps still? With the
weird year I wonder on this at places.
Have you tried open the L side up a 1/4 turn?

Not sure but something is up for sure. All three doing the same
thing rules out the saws or weedeater. Do you know where I can
buy non synthetic oil mix

Husky oil is semi synthetic
I run 100% synthetic oils.
Poulan oil in black bottle was husky dino oil. If you can find
it. I used it till 2004 or so till I went 100% synthetic

So maybe it is the gas and not the oil causing my problems

I doubt that it is the oil or the gas causing your problems.
It could be that your equipment is getting older and could use a
retuning of the carburetor. That is why Cut4fun suggested that
you turn the L screw on the carb 1/4 turn ccw. That will
richen up the mixture a little at the low rpm range. When 2
stroke engines run on the lean side they get hot and if too hot
it will cause problems. So try and adjust the carb and see if
that helps.

Could just be the hot weather. Not sure where you are located,
but from the date of your first post, that was when we in the
Northeast got our first dose of 90 degree temps for the summer.
The fact that it happened "all of a sudden" to 3 units kind of
eliminates the machines themselves. Every time the temps jump up
to 90 like that we get a whole bunch of hot start complaints of
all kinds of stuff. There really isn't much we can do. Had the
same problem myself last week on one of my own saws. In fact it
was also a 55. Took several pulls to get it going. Setting the
high idle helps. Big difference with these little air cooled
engines when the cooling air is 90 vs say 50 degrees.

I have seen some vapor locking of the fuel in very hot weather
on some of my saws. Never thought to consider that hot
weather could be the issue here.
+1 Spike.
