FX Engines K303 DLC .21 3-Port Off-Road Buggy Engine Combo w/2131 Pipe

Just got done with my break in process and just put a decent race tune on it.

First off the packaging and presentation is amazing, you can tell they really go the extra step with their products! I first started the engine after warming it up to 240 degrees and it idled really high, you will need to reset the idle gap to .50-.60mm before you fire up. Set the midrange to .10, and this will give you a pretty good baseline for the first and second tank. Might need to lean out the LS a bit until you get a decent idle. I’m about 8 tanks in and this engine rips, it’s got some really good power and sounds really deep with this pipe combo. Engine is running great now and I don’t have any complaints! Just what you expected from the man himself, Mr. Hudy.

I got this FX engine from a friend of mine who just had it serviced and re pinched with new bearings after he put approximately 4-5 gallons on it. It’s in my practice car and I just beat the holly poo outta this thing. Just cracked open the 9th gallon and she is still making great power and easy to keep a tune in it. Not the best mileage now as she is getting a little tired but still hitting 7:08 on the clock. Definitely has me re thinking my next purchase for a race engine.
