4 stroke starts but won't run
Hi guys,
I've been out of the hobby for a few years, back in flying electrics a year or so back, and now it's time to resurrect my higher performance nitro engined aircraft.
Apart from some gumming up, they seem to be OK, but one of my Magnum 90 four strokes won't run. It starts readily, runs for less than a second and quits.
I've tried flushing the tank with methanol, then flushing with fuel, made up a batch of new fuel, and changed the glo plug twice, but exactly the same problem. Other engines are running well on the same fuel.
I'm thinking that it may be the fuel system because due to space constraints, and CoG, I have a main tank and a header tank. The problem is that accessing the header is not easy, so I want to exhaust other options, if any, first.
Any ideas on what to look for/at??
