Is the Central Hobbies nose ring for a YS 175CDI supposed to be a snug fit on the engine? The one I just got from Central Hobbies has about a 1/32 inch gap all around the engine.

I don't know about Central parts and it might warrant a call to them, but I never had a nose ring that had a gap around it and the engine.

jkruger,

The 175 has the same diameter as the previous engine versions, it seems you have an nose ring wich is out of tolerance.

Talked to Central Hobbies and they recognized the problem. Has something to do with the YS soft mount and its requirement for a nose ring. The fix is to replace the rubber gasket with small fuel tubing. Central Hobbies is sending me a modified nose ring at no cost. That is service.

It has to be firm, I will sugest to fill the fuel tubing with RTV, that will give the necessary support.
I support your statement about Central Hobbies, on top of the best HS for sure.
