I have a Ramrod 1150 with a Kaw. engine. This only happens when I'm running my tiller or trencher (hydraulic) and it's over say 80 degrees. The motor will begin to starve for fuel and die. Choking will not keep it running. Fuel line runs across hyd. filter and return line, and I moved it as factory suggested, also replaced fuel lines and filter. Kaw service tech dissassembled the carb and found no probs. This only happens when I've run it a bit with a hyd. attachment. If I wait a few mins. it will start and run again for awhile. There seems to be very little fuel in the filter when this occurs. Factory of course says they've not heard of this prob. RRhhiiight. I have seen a post here about it. Any suggestions besides getting rid of this machine? I've owned three and think they're great when they aren't broken down.
