Enya 61 max. rpm's ??
 

Hi everyone , I have a Enya 61 that just doesnt seem to go to full throttle when opened all the way up. I have tried a 11x7 , a 12x8 ,13x8 , and a 12x6 prop. The throttle barrel is opening all the way and it has plenty of tank pressure with no restrictions in the fuel line or the muffler pressure line. Rpm's with the 13x8 is 5200 and with the other prop configurations its max is 5800 with the 11x7. Any info on the engine would be appreciated. I have tried various needle settings and it has not increased by more than 100 rpm's even when running lean. Idle is great and so is transition. Isn't top end suppose to be around 8000-10000 on this engine? Thanks
