Are Husqvarna's coldblooded?

[dolittle]

My manual says Zama and of course I know nothing about engines.  There are 3 holes in the side for idle and carb adjustment which is done at the factory.  The idle has a t slot but the L and H are tamper resistant.  Something new.

The final carb adjustment should be done by the dealer. Different areas of the country with different elevations require different settings. Some dealers are better than others at setting up new saws. The limiter caps are designed to intimidate homeowners away from messing with the adjustments, they are not 'set and sealed at the factory'.

I have been able to adjust the settings so it does not bog down or stall but it still has some hesitation.  I am somewhat disappointed with it and the dealer has been very good to deal with so I am returning it and getting a 346xpg and staying with the 18" bar.  He only has the 346xp in stock so it will take a week to get the xpg.  Thanks for all the help you guys have given me.  I am hoping I can absorb some of the knowledge on this site.

Yes and yes (IMO)  ;D

:D :D .....and yes again - the best 50cc saw out there, all things considered...... 8) 8)

..and the heated handles of the xpg are nice....

Does the saw have a small (aprox. 3/4"x3/4") metal plate that is used to block off air between the cylinder head and the carb?

I have an 262XP and an 575xpg both of these saws have this plate.

When it is hot the plate is left blocking a hole that has to be punched out of the top cover between the cylinder head spark plug area and the carb area.

When it is cold you remove the plate and slide it into another slot by the engine then hot air from the head warms the carb.

Your owners manual should describe this operation under the heading COLD WEATHER OPERATION...or a similar title. 

The plate works like a flap on a auto air cleaner only it in not automatic: you have to take it out at the beginning of winter and replace it when warmer weather returns.

My 575xpg is cold blooded but it improves somewhat with this setting.

All new saws that might pass EPA specs are going to be cold blooded, lean as they can be and still run.   Steve
