[NSRCA-discussion] Engine problem

[William C. Harden]

I suggest that you buy a replacement head because that is the only item you
need.  In the future, if you have a stripped glow plug thread in the head
then simply replace the head and avoid this kind of problem.  The heli coil
method works, but it is better in my opinion to have a new head.  A new head
really doesn't cost that much.

General engine problem

I have a YS91AC that runs fine but leaks fuel around the glow plug.

It appears that the plug is not square to the head casting so the 

copper gasket does not completely seal the joint. 

 

Before I take the problem to my machinist son-in-law are there 

any suggestions as to how I might resolve the problem?

 

History:

Bought engine at deep discount with damaged threads and had 

Clarence Lee install helicoil insert. The first owner was full scale 

engine mechanic so I expect the problem was from the factory.

 

New YS110 is listed at $329, new head-cylinder/sleeve about $150.

My personal threshold is not to spend more than 1/3 the price of a 

new replacement in repair parts. 

Ideas?
