What is the difference and your recomendation?
Thanks in advance.
Hi Guys. Back from the frozen tundra and into the 70 degree weather.
criss, you can break in the engine with whatever fuel you will be running. I think the directions have to cover every level of ability, and for a very novice RCer, it's probably safe. If you have any engine tuning experience, as long as the engine remains rich during the initial running stages it will be fine.
Right now I have to say the 2058 is the way to go. Gobs of power, smooth delivery, and a little quieter than the 2013. If you don't mind the bark of the 2013, it's a beast tho.
... 2013 isn't as smooth or mid-range type power like the 2058, just a lot of it when you pull the trigger and screaming top end. 2013 isn't legal at EFRA events or other European races.

I am not sure how accurate the HP ratings are but the Alpha Disc. states 2.7 HP and this one states 2.65 HP. I would imagine the 3 port would achieve a little better fuel mileage. Which I feel is the more important statistic in racing with reliability being next.
The 3 port has a ceramic bearing, and a lightened head, plus it's ABI which means basically blueprinted engine. The 2066 isn't my favorite pipe though, and it has the composite carb too. You really need to seal these carbs up and check all the orings. It's plastic so all the fittings and seals need to be inspected and sealed. This is a great engine though, one of my all time favorites.
You can get
great fuel economy out of this engine if you set it up right.

Cody ran a variation of the Worlds engine. Basically a 5 port with the new crank case material, but the porting and crank timing is slightly different than the Worlds engine. This was one of the engines we tested but didn't use in Pattaya.
