I had this spate of problems too and tried everything I found on the net like the advice from freestyle3d as well as other members.
In my experience, here's what you need to check;
- Fuel tank does not leak.
In my case, I filled the tank with fuel, then closed all but one of the outlets and force injected more fuel using a syringe, to my surprise, I found fuel squirting out on the unused holes in the stopper. Try tumbling the tank a bit while doing this to check for all possibilities.
- Stiffer clunk line.
Following freestyle3d.com advice about doubling up the fuel line in the clunk, I did this mod but doubled up the fuel tubing not just from the nipple, but all the way to the middle of the entire length so the clunk is flexible, but gets stiffer as it goes to the nipple in the tank.
- Engine scoring
The above 2 worked for awhile, but after my recent flame-out (rolling inverted) I finally got down and took the engine down and checked the piston and cylinder for scoring. Sure enough, my piston and cylinder were severely scored so I overhauled the OS61WC.
I too have just bought a YS80 w/ 93 main gear and 11T pinion and after the holidays, I will probably try it already since I think the Freya needs more muscle anyway. |
