Chainsaw Repair

I worked on this guy's old Dolmar over the winter.  It had a Tillotson HK-21C carb in it.  The carb gave me fits.  I eventually got things running, but it wasn't up to my standards.  This guy is an old friend.  So, I sent it out the door and ordered a spare carb.  I told him if it got to where he couldn't stand it, bring it back and I'd drop that new carb in.  Email comes in about 2-weeks later: Back-ordered.,.we'll have it in a couple of weeks.  Back and forth this goes from January until today: Item is discontinued.  We can't get you a replacement.  But we can hook you up with a Walbro HDA-22 at a discount price of $127.50.  It goes without saying I didn't bite on that hook.

I don't understand why a company would operate like that. 

I won't name the company in here, but will provide in a pm. 

In the meantime if you run into one of these old HK-21C carbs, let me know, please.  Thanks.

just out of curiosity what is the model of the saw? i am curious to see what comes up through dolmar for a carb. The HK-21C immediately comes up as NLA through my distributor so i dont understand why they would even take your money on that one

Info from member 166 brother.

Till HK carbs are very temperamental the plastic module body that houses the metering lever is prone to warping pressure check the carb while dipping in a can of fuel look for body leaks

part #s till carb 112 150 002 module body # 112 150 450 alternate carb Bing 48B102 #114 152 000


module body in stock $13.00 + S&H

It was a Dolmar 112.  And the leaking plastic piece holding the metering valve fits the symptoms. 

Thanks for all the info. 

Right off the bat I notice the 23 is smaller 13.49mm Venturi compared to the 22     16.66mm Venturi

 The IPL shows the HDA 22 being $127 though, like you were told.  http://wem.walbro.com/walbro/product2.asp?Series=HDA&partnum=HDA-22-1
