Good afternoon,

on behalf of my AME (who has already made some enquiries to members on this list) I have a question:

Number four cylinder was 50/80, exhaust valve leak suspected. When checking the cylinder, the exhaust valve guide was turning.  He suggested he didn't think it was supposed to. Apparently he checked with George Coy and Walt Lannon (thanks) who both think that if a new cylinder is needed, then a M-14 cylinder will drop right in (apologies if I have this wrong). I cannot confirm this with Doug or Jill - both away.

In short, why is the valve guide turning? can I replace the valve guide or do I have to replace the cylinder?  If the cylinder, will an M-14 one do? Apparently, Doug had no HS6A ones available.  The plane is in Canada so not keen on shipping cylinders back and forth across the border unless I have no choice.

Input gratefully appreciated as my AME has stalled.

Thanks,

Phil Nicholson

The cylinders have the same basic dimensions, but are not the same. As I mentioned I have a few used cylinders here, but are very old. Perhaps someone on the list can provide a good cylinder for a Housai.

Good afternoon,



on behalf of my AME (who has already made some enquiries to members on this list) I have a question:

Apparently he checked with George Coy and Walt Lannon (thanks) who both think that if a new cylinder is needed, then a M-14 cylinder will drop right in (apologies if I have this wrong).

In short, why is the valve guide turning? can I replace the valve guide or do I have to replace the cylinder?  If the cylinder, will an M-14 one do? Apparently, Doug had no HS6A ones available.  The plane is in Canada so not keen on shipping cylinders back and forth across the border unless I have no choice.

Agree with George. They are not interchangeable.

Give Allen Barrett at Barrett Precision Engines  a call.  He may made be able to fix that cylinder for you.  His  number is 918-835-1089 and you can see the web site at www.bpaengines.com.

  

 He may be able to machine a valve guide.  Very down to earth guy and  really knows engines.

Phillip;

  

 You definitely have this wrong.   I did not suggest that an M14  cylinder would be an acceptable alternate.  I simply suggested that Jill,  or George Coy, may have access to a spare Huosai cylinder.
