Hi B_S,

Firstly a big warm welcome to the ODK Forums.

You have a late 1975 built Model 45 with either a HK25 or H4 power plant fitted.

Now I know you've read a bit about the Kirby engine and I also do not hold it in high regard either, but in saying that if it runs ok then I'd hang on to it until something more terminal happens. I had an original HK30 on my 20 inch machine until it went pear shape and then I replaced it with a much later model Briggs which isn't that good vibration wise either. I am going to replace it with a current I/C Briggs or Honda if one becomes available cheap enough.

I notice you have the engine removed atm and while you have this situation I would have a really good look at the engine mounting rails and inspect closely for any fatigue fractures. I will say that with it being a 14 inch machine it will probably have none but then again it's good to check while you've got the power plant removed.

If you are in the unfortunate situation that you do then it is imperative that this issue be rectified before going any further.

Let me know how the rails are before we proceed any further.

Cheers,
BB.
