RE: mvvs 58 limited edition
Hi Pe, season greetings to you.
My engine has developed another problem in that it has a misfire, it was running good then the prop came loose so I landed, when I retrieved the plane the prop was quite loose on the crankshaft but after a while I went to tighten it up but it had gone snug so I screwed the nut back on and tightened all nuts and bolts, I had another flight and all was ok. Now the next time I flew it (different day) I was in about 5-6 minutes of the flight when the engine went rich or so I thought in the mid range alright at top and bottom but anywhere in between very rich so I took the cowl off and tried to retune but to no avail now it's getting worse because the top is misfireing as well now. I can see that there's a woodruff key sticking out between hub and crankshaft housing locating the hub, is this normal as I don't recall seeing it before but then I never looked that close before.
Your thoughts/advice would be appreciated.
Steve
