Ok, have had a number of mechanics look at this, replaced the carb (got new), fuel filter (got new), new fuel, new prop, took exaust out of system with bypass to see if back pressure was issue, compression is not perfect, ranges from 75 - 110. Runs perfect in neutral and reverse, she bogs and stalls in forward. Checked the tranny, looked ok, but am thinking that must be problem. Next thought is to detach the shaft to eliminate that issue and see if it bogs just shifting - ANY OTHER IDEAS ??
