Hi, just bought an old white snowblower 8HP with Tecumseh motor. I need to find the part number before ordering a new carb because this one is leaking gaz. My motor number and serial: HM80-155006 SER33160D (NOT SURE ABOUT THE *D*) FLOAT STYLE carb My carb have idle mixture screw and the main mixture screw under the bowl. Let me know if you need more info or maybe a photo to get the part number to find my replacement part. Thank you.
