Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Hi Alistair

What are the valve seats like, are they still up level with the chamber and still capable of being recut or lapped.
How much are you asking for them.

I assume they are both front cylinders.

Im in Australia

Thanks

Eric

alistair

they are fairly greasy and dirty.
i will give them a clean up and inspection on the valve area and let you know.
do you have an email address i could send further photos to? its easier than this website.

Hi Alistair

My email is ericsinaus@yahoo.com.au

Are there 2 different sets of barrels (4) because a pair the fins are complete and in the other photo one of them looks like the fins on the head are all broken.

Can you give me your Phone number so I can call you. to get this clear.

Thanks

Eric

alistair

cheers .

Hi Alistair,
Quote... its easier than this website.
Have you tried the new attachments process yet? It is a lot easier and quicker than the old one.
There are two ways to attach photos now, both can upload ten photos in one go.
