A new pull start utilizes a one-way bearing encased in a large 14mm hex for increased durability.The F4.6 is the Powerplant responsible for the immense speeds and raw torque in the savage x 4.6, and now it's available to fit into any savage or big-block monster truck! It features all the race tuning you could ever want in a big-block monster truck engine, fantastic good looks and plenty of attitude! With 2.9 Horsepower on tap, it really is true that there's no replacement for displacement! With 8-port race tuning, you get a huge power band through the entire rev range, All the way up to 32, 000rpm! The composite 7.5mm carb is heat-resistant for consistent tuning as the engine warms up.

Extremely impressed with this motor! And why shouldn't I be! HPI produces durable H O motors at a great price. I installed this .28 power plant in my 2 nd Savage that I recently purchased with a blown motor. Let's just say when truck hits 2 nd gear.... It pops a wheelie! Couldn't be happier

I put this engine on my savage 25. When trying to break the engine in it would go right to full throttle. Checked all linkage and checked engine, carb, and gas tank for air leaks. Everything checked fine. I swapped the carburetor with the one from my old 3.5 engine and was able to get it to idle through a tank of gas for initial break in. I can only return entire engine and carb together I guess. I don’t want to do this since its not available anymore. Not sure how to get in touch with anyone since the return process seems automated, so maybe someone will see this and help me out. Maybe not
