Tillotson HL series.

Would any Tillotson carb gurus know the specs of a HL-87C carb?

Thanks.

Its a Mcculloch chainsaw carb. You might wanna google that carb with Mcculloch in there and see what results you get.

Your other thread seemed to answer that...
19mm to 20.2mm isn't going to make much difference in running, FWIW

I was getting confused between throttle bore diameter and the venturi diameters. I was measuring the throttle bore section of the carb thinking this was the venturi diameter. Now that I'm thinking about it, I've probably passed up a few HL carbs that I thought were to big.

Most saws with this type of carb have something with a 7/8 bore and 5/8 venturi.
You can tune them to run a clone but they are so close to same as what was on it in the first place I am not sure its worth the trouble.
Old too so it probably needs a rebuild.

RK-88 is probably the right kit.

check the throttle shaft odds are if the saw was used up the carb is too and the shaft is worn out.
