Had some problem past weekend with the Onan B43G engine surging and eventually a few back fires and died. Cleaned and re-gapped the points at 16 and cleaned and tightened up the carb. Ran good after that so mowed today and after about an hour it started doing the same thing. It starts and runs with the choke out but even then it surges. I did install an electric fuel pump last year but have never had an issue with that so I think I can rule that out.
Can anyone offer any ideas/suggestions as to what to look at next?
