New 365 wont start with decompression valve in

[Stubby]

The old 365 was 65cc, then the special came along (70.7cc), the current x-torq version is also 70.7cc

The special also had the bottom end of a 372 so slightly over engineered saw that would go on for ever ....

my one is 365 xtorq 70.7 cc and like i said you be pulling for a month of sundays if you use the decomp valve i now use it with out and start 2nd or 3rd pull and its no harder to start on pull effort to a ms181

Thats the way to go then !

the decompression buttons 'work to well' and there is barely enough compression left for the saw to fire.. thus it takes alot more effort.

 

stock 365/372's do not have uber high compression to start with...

 

just dont use the decomp, the starter assemblies are plenty strong enough to take the extra force. not a fix, but its just one of those things

have dealers tried sorting it out?

i did not speak to fr jones, but have they heard about it

365s tend to have around 145psi when run in and reckon that using the decomp is taking this down too low for combustion.

 

Some larger saws do run on a lower compression than their smaller cousins - just use the saw without the decomp:thumbup:

My guess would be the de-comp buttons are not poping out when it fires . Could be a faulty batch of de-comps ? My 10 year old 372 XP pops it out on the first cough on choke and you have to push it back in for the next pull .

 

Could be something along those lines. Our 3120 doesn't pop the decompression valve but still fires and runs ok though, thank GodI ! I wouldn't want to have to start it without the decomp valve!

I have 2 new 365's and neither like the decompression switch.

Bet its to do with the eu regs making saws 'weaker' in our eyes, that whats said bout a faulty batch

Recently brought a 372 and they said if I had problems with the decompression valve they would change free off charge so it could well be a problem huqvarna know about
