Getting past the first tank of gas was the hardest part. Each tank of gas got a little smoother running and easier to start. The engine was nearly impossible turnover when it was brand new. I thought I was going to break the pull cord. By the third tank of gas it was running smoothly and the engine was apparently quite fast. Despite the difficulty breaking in the engine I would buy one of these engines again.

This traxxas engine is fast but tuning is difficult starting is difficult I gave it 3 stars because it seems to be a very difficult engine to run and for the amount of money people spend on these hobby rc vehicles the engines should be easier to use and less frustrating it is a fast engine with good power though and traxxas has decent customer service

2nd 3.3 engine .. thought first one blew up that wasn't the case. New fuel tank had to tighten screw inside cap or both Motors were puking fuel out the exhaust that way ....I recommend it

If you follow the breaking in procedure along with the tuning guidelines as written in the manual you'll have a tight strong engine with hours upon hours of use hassle free. I was at first hesitant to change over from the EZI start system however it won me over easily. I attempted a rebuild of my old engine with not much success, not to mention the cost in a rebuild (bearings, piston, liner and push rod, just the basics) Then reading through forums they nearly had me leaning towards other replacement engines and even contemplating a conversion to electric. With Traxxas exchange program new for old engine I'll be sticking with the Traxxas 3.3 Racing Engine.

The box was not factory sealed. And was hard to turn. After removing head & adjusting cylinder sleeve. It's a great running engine. Just taking my time breaking it in

It arrived a day early and has worked flawlessly. It was also cheaper than any other option.
