Hello,
I've got an 066 that has been getting progressively harder to start with some serious yank-back on the handle, like can't hold the handle/bruised knuckles kind of hard.
I've read some other threads with similar sounding issues, particularily this one:
https://www.arboristsite.com/commun...l-038-hard-to-pull.131853/page-2#post-4188286
with likely flooding issues, and this one:
https://www.arboristsite.com/commun...er-rope-like-last-084-post.44726/#post-604258
(leaky needle valve in carb for also flooding issues?).
So I thought this might not be too bad to fix, and have pulled the carb off entirely - however, it is still really hard to pull even with the carb completely detatched!
I have also removed the muffler - no help there.
When I unscrew the spark plug, it turns over easy - as soon as I have the spark plug back in, even just finger tight, it is hard to pull.
So what is going on here - am I fighting some sort of vacuum force in the piston that having the spark plug out alleviates?
This 066 does not have a decomp valve, just a bolt in there - should I consider getting one? Would it even help?
Thanks!
