Os FS 120 Surpass (pumped)
One of our club members has an OS FS 120 Surpass (pump). It runs great in straight and level flight , but when he goes inverted the motor begins to cut in and out until he flips it back over then it runs great again. We have checked the lines for kinks and splits.

RE: Os FS 120 Surpass (pumped)
It sounds like you're using a short lenth (as in normal) 2 stoke glow plug and that never a good idea.
Try an OS F-type.
The only other plug i'd say worth the time of day and works A-OK on a 4-stoke is an Enya Nr.3
