Hi Zute
Djam also makes a point.
The strange thermostat bypass these D2s have may have a bearing on you.The motor needs to be operating at over 1500rpm to open the relief valve to fully open the circuit(CORRECT ME IF I HAVE IT WRONG FELLOW BRAINS TRUSTS!!!)
If you are going slow and doing it tough you may be copping overheating from the above.
GOODLUCK,there is good AULRO help in the Alice
