Questions & Answers

This is supposed to be a replacement for my Tecumseh carburetor, but the needle is longer than the original and when the new seat is installed, the float is jammed tight with no lever action.
Sandi for model number HM80-155316P asked on 2019-12-13
Hi Sandi, Thank you for your question. This should be the correct part based on your model number. Here are some installation instructions that a customer posted on our website that you may reference to see if this resolves this issue. "Removed, cleaned, and disassembled carburetor. You will need to use compressed air and a blower nozzle to remove the old float needle seat. Just apply air pressure to the fuel inlet fitting. BE CAREFUL to hold the carburetor away from your body when you do this because the seat comes out with enough force to damage an eye if it were to strike your eye. Replaced old float, needle, and seat. Be sure to press new neoprene seat all the way to the bottom of the bore it seats into. A pin punch that fits inside the bore is a good tool for this. Just press with your fingers, not with a hammer! Assemble the float, the needle, and the float hinge pin. Turn the carburetor upside down, and adjust the float so the top of the float (bottom when upside down) is parallel (but not even) with the top of carburetor fuel bowl. Carefully bend the float tang that presses on the needle to achieve this position. DO NOT PRESS THE NEEDLE AGAINST SEAT! Use only the weight of the float to press needle against seat. Reassemble the carburetor using the new gaskets and o-rings from the kit. To replace the primer bulb, you will have to pry out the retainer ring holding it in place. The retainer has teeth facing outward to keep it in place, so it requires a little force to remove it. Be careful not to score the walls of the primer bore with your screwdriver. Press the new the primer bulb into place using a socket that will fit in the the primer bore. Be sure to press it all the way to the bottom of the bore. Reattach the carburetor and linkages. NOTE: It is a good idea to take a picture of the carburetor linkage before you remove the carburetor, so you have a reference to assist you with correctly reassembling the linkages." If this does not help, and the part will still not work, you may have a defective part or the wrong part was sent you. If you placed the order with us, please provide us with your order number and we would be happy to help you with this. We hope this helps. Thank you and have a great day!

  • Ethanol required repairs
    The ethanol fuels ruined the rubber seals and plugged up the carburetor, I ordered parts that were listed in stock but had issues due to the Covid-19 impacts and waited 3 weeks for shipment and one item ended up being out of stock. Great customer support just impacts due to Government shut downs.
