Hello - I have an old two-cycle Jacobsen 9” Edge-R-Trim with the 321 engine. It is in great shape and receives regular use. I began to notice fuel leaking from the float bowl and found the threads in the Walbro LMB carburetor body where the bolt that holds the float bowl on were very corroded and essentially stripped out. I tried drilling it out and installing a heli-coil, but this didn’t work. I don’t believe the LMB carburetors are made any longer (at least I can't find any), but is there an equivalent carburetor I could purchase? On the right side, above the LMB, is the number 172. On the left side, there is the number 273.
Thank you.
