Hello Bax!

Have a couple of question about my FS 70 Ultimate engine.

I can´t get it to run good. It´s very unstable. I´ll try the proceedure you explained here: http://www.rcuniverse.com/forum/m_28...tm.htm#2881118

Question 1: There is som air bubbles in the tube from the pump to the carb. Not much and not all the time. How much is acceptable?
Question 2: There is som oil coming out of the pump air inlet - the line named D in the manual. The manual says that if there is a noticeable amount of oil coming out, send it in. Is some ok, or is the pump leak.

The engine have had a gallon of fuel. Is it worth wasting fuel - or should I just send it in?

Thanx
