Hi I have a j d 318 that surges.I was told to take off the intake & carb & to clean the carb & take the manifold apart & clean it & put Moto Seal gasket maker between the 2 sections of the manifold & that would stop the surging. Has anybody heard of this fix. thanks for your input. tom

Yup...I don't own the Onan eng...have heard of this routine...But< I would first try a quicker resolve...Remove the big bolt on carb bowl, drain the fuel, poke a wire straight in to ensure main jet is clear...Reinstall bolt...Test run...while spraying carb cleaner , carefully, on intake manifold, looking for change in eng RPM...if no change, then manifolds two halves are still sealed...If still surging,, will need to remove carb and overhaul it...
