Chainsaw Repair

Rk24HS Tillotson kits most of them.

The HT was built using the HS metering parts and pump parts,same carb kit applied.

HT-12 uses a different kit again. Dont recall using that on in the  1 3 5 7 thinking needles were different when I was doing them, one you mentioned. Just a WAG

It does list a 084 though too.  But not the carb 1 3 5 7 etc
