Use to have one. Was my first gas engine, the "i" version, rear carb. It would spit fuel into the radio compartment till I installed a bugle with the foam filter. Solved that problem. Then it started to get really hard to crank because it was not drawing fuel. Sent it into Cactus and they found the isolation block was leaking so the pump would not work. Found out later this is a common problem with the early versions. Maybe they have improved the design. I would still rate the engine as good with good power. Very solid casting on the case. Would I buy another one for a special project?-probably so.
