Are you running the Torquemaster with one of the packs which Hobbico sells or a 12v pack?

If so, RUN, do not walk, and get higher VOLTAGE packs ( or make one up ).

I use 14.8v racing packs on my regular torque master, and others at my field use the same starter with 18v packs to turn over engines up to 1.80

With my High Torque Torquemaster and higher voltage packs I have no problems starting up 50CC engines.
