got my new 4-tec in yesterday and ran the first tank of fuel through it and man i am not beleiving how poorly it performed its
hard to believe that it will run alot better
after break in it was so sluggish but i know it was because i am breaking it in can't

be done with break in today.

Tip. If you take off the glowplug and turn the flywheel by hand a couple of turns you should feel no resistance when the piston reach the top position. If you feel resistance it´s only to continue breaking in. This is the only way to know when the engine is fully breaked in.
