That's $25 after freight. Yep, decent price for that carb. You'll need the seal o-ring for the compensator end. If your saw does NOT use the compenstor, just put on the standard metering cover from your old carb.
Just for consideration - for a few $$ more you can get a brand new walbro WT194-1. The 426 is only adjustible within a limited range (usually o.k. for most simple muffler mods, but I have had two that I couldn't richen unough without re-jetting). The WT194 is adjustible across the entire range... The WT194 does NOT have the compensating end, but you just take it off your existing carb if you need it.
And Ultra - the answer is YES - as soon as the post picks up (even they can't get here today!).
