Brand New EVERYTHING - Misfire on 3&4 - HELP

[racer86]

Morning All, hope you're well and staying safe.

 

Firstly, I wanted to thank you all for your help, advice, suggestions and moral support during this miserable issue! YOU ARE LEGENDS! 

 

I got the manifold back from the machine shop yesterday and put it together last night: New BMW gaskets and a dab of sealant for good measure: 

 

 

 

 

Now I've not driven it, but I can confirm having started it and ran it up this morning IT RUNS PERFECTLY!!!!!  I've changed a few things like the timing, points gap, brake booster hoses, posh BMW gaskets and the machining etc. but ultimately I think IT WAS A VACUUM LEAK as expected and it was just a case of hunting it down.  

 

I can't wait to get it back on the road now and have a blast!  Thanks again all. I am OVER THE MOON!
