Hi there. I am having some issues with my polini thor 100. I've done about 30 hours on it since acquiring it second hand, previous amount of hours were unknown.
Brief history:
Was prone to fuel starving (presumably) if not primed correctly. Had been flying a revo 2 26m wing which wasn't too demanding on the motor so this never starved, then a 24m gtx which had no issues, started flying an itv wing and I had a load of problems, mainly maintenance issues all of which are now remidied with a carb rebuild, new gearbox gaskets and some bearings.
Went for the first flight on 6 months and the motor cut out just after climbing altitude, the motor had been up for 20mins.
Can someone advise me on how the fuel system should be setup, there's a kink just before the prime bulb which may be the root of my problem, is there any reason to not replace the fuel lines to the same thick gauge that's used above the prime bulb? There appears to be thin tubing, then thick tubing after the bulb. Also is the high point a problem? Air often seems to get trapped in their however this may be due to restricted fuel flow because of the kink.
Any help or pictures of setups would be greatly appreciated, thanks.
