  • G23lh problems

    My g23lh will not start for the absolute life of me. New gaskets up top, rebuilt and cleaned carb, new spark plug and fresh gas. It has compression but I get no ignition whether bump starting or pull. Any help appreciated.

    For no spark, Check your magneto to flywheel gap. Check your plug gap, also, pull off the stock kill switch wiring <- it’s been known to ground out.

        Sorry I forgot to mention. Brand new spark is firing correctly. Flywheel and magneto are spaced correctly. Leading me to believe it’s a bottom end problem

          So I put a little gas into the cylinder and got a couple fires out of it. After that went straight back to bogging and died again. The only thing I haven’t checked is the crank seals and bearings. Could that be my problem?! Also my carb has a single adjustment needle. Couldn’t find anything on tuning that although obviously left is rich right is lean. Played around with it with no results.

            Its obviously not getting fuel. Try buying a new carb and matching gaskets. A 167 is a good upgrade carb.

                  I put 2 different spare carbs I had that both fit but I ended up with the same problem regardless of tuning.

                    You may have an air leak. Try a new 167 carb and all new gaskets all around. Get genuine walbro carb, not ebay or clones. Order from DDM or ADA Racing.

                    This is the best HP carb for an lh.
