the problem is you ran it in as per Ofna instructions.. Just a general rule. Never follow run in instructions from an engine manufacturer.. all they want is for your engine to blow within the first gallon so you have to buy another.. Let me guess they said to run rich on the block for 2 tanks or something.. ?
Massive...you got a PM!!
I would give a tip on the Hyper MSN, but some guys said the information that I got from OFNA directly was wrong and I'm tired of "know it all's" on this site who don't know it all!!
I replaced my carb with a OS 20e carb and it ran much more consistant and held a tune.
