I am flying a very common Fury Extreme set-up:
YS80 STII
Hatori SB-16
9252
401/9253
Futaba 8UHP
GV1
etc.
The problem I have is that after each flight I notice there is a tremendous amount of fuel that puddles (actual it completely covers) on the bottom plate of the helicopter. I use to just pass it off as acceptable because I have run the engine rich for quite some time for break-in purposes. I have recently leaned it out some but definitely not to the point where the smoke trail disappears. Not even close to that.
I recently switched from Magnum 30% to the new Curtis 30%. I went out to start the machine yesterday and it would not even idle. This is the first time I have ever had starting and idling problems. I noticed fuel dripping from around the outside of the cylinder head fins and collecting on the bottom plate. It really appears to me that I am losing a lot of unburned fuel. This machine has never really been all that good on "gas mileage". The engine has probably 3 gallons through it so it isn't a matter of it being worn out.
I would say that my next step is probably to pull the engine and check for anything unusual in and around the carb. I need to pull the engine anyway because my optical pick-up on the GV1 doesn't work and I want to convert over to magnetic.
I am running a header tank just like most of us do. I changed the glo-plug (Enya 3) and it didn't help.
Any assistance would be greatly appreciated. If I need to take some pictures of the machine I can do that.
Thanks
