Guys thanks for all the comments. I have had to order a separate primer plate gasket as these are different to the normal Briggs and Stratton Primer Plate Gaskets. The engine still starts first pull with a quantum gasket but I�d prefer to have the right part in place for starting longevity. I must admit these are a strong engine and perform really well after a good service.

I still have an issue with the Rocker cover after I reset the valves. It is still leaking oil ever so slowly and I can�t work out why. The cover is nice and straight with no kinks. I sealed in all up nicely with RTV silicon which has always worked perfectly on the OHC Honda�s I have worked on previously.

AVB mentioned the 2 bolts under the rocker arms. I checked these and they are tight.

I let the RTV go tacky (2-3 mins) before I joint it to the engine as per the instructions but it still leaks. Both contact areas where cleaned and dried with turps, so I am a bit stuffed as to why it wont stop leaking! I have fairly good eye sight and to me the OHV cover is not bent out of shape!

Would love any suggestions!

Peter
