I attended Husqvarnas annual service update school recently. with over 30 techs the 562 was a non issue, for the technical rep from NC it was the white elephant of the day, (he was waiting for lashing on the 562 that never came) Troubleshooting, then proceed as is, in most cases swap out the carb. Done deal everybody goes away happy.
The other side of the coin lets chase our tails and not know nothing about nothing and find an excuse. This is no different than vac and pressure testing a saw, something most fail miserably at or even fail to do.
Work orders with 10+ hours($750) for a saw worth $300, go learn something or beat your head with a hammer.
Yeah a new 46 will fix a bad 46, but hey you cant even get a 46 anymore so its 48 time.
