Have a new gx 390 and its only done around 80-90 hours since arriving, its a pull start and used to fire up immediately even if you gave it half a lazy pull, Now it needs 4-5 attempts to get her going in the morning, once fired up she's great, ran very low on gearbox oil 2 days ago due to bubble stuck on top of sight glass giving the appearance she was full, now i only check thru filler cap, worried this may have had a detrimental effect, any info would be great
