346xp - fuel problem?

[Dilz]

Had a 346 sat around for a while. 

 

It worked ok but some times would bog down on high revs and needed feathering to get back up to speed -  eventually just refused to do much at all, but often would start fine and idle nicely only to die shortly after putting on some revs. 

 

I've cleaned and adjusted the carb, and still had problems, a bit better but still useless (checked the cylinder and all looks fine - no scoring) 

 

then i noticed that what i think ( ) is the impulse line not sitting right.

 

Got this sat on better - so now the saw runs great  - but only when the saw is at a 45 degree angle to the side. 

 

Revs drop off on idle and it bogs down a bit when on full throttle when its in a normal position - had to leave it for now as got other things to do. 

 

Now wondering if it could be an issue with the fuel filter or something else... Wont have time until next weekend to look at it.  

 

Thanks in advance for any tips.

Just do a pressure and vacuum test and if OK, work through the fuel system.

The 45 degree angle sort of makes it sound like there is crap in the gauze carb strainer and at an angle it clears the issue. It is also possible the fuel line is holed and at 45 degrees, the hole is submerged in fuel thus sealing it.

The 346 has a weak clutch side seal and the inlet manifold can split and cause issues - that's just how it rolls!
