Riddle me this: What would 18 psi do to a set of DCOE weber carbs

[LeonV]

I'd guess the loose manifold bolts had opened up an air leak. Glad you got it fixed!

May have found another reason 

I swapped out the hypo jets I have been running with standard 60F9 

and the problem completely vanished 

upon cold start the engine felt smooth and ran very well.  She is back to her old self 

When I torn apart the hypo jet it was badly gunked up with varnish on the small tube that resides inside the jet housing 

I have them soaking in some carb cleaner now.  But that may have been an issue 

 

[LeonV]

Why do your carbs have so much varnish in them? What fuel do you use?

[Zedyone_kenobi]

It sat for 4 months while I worked on the roadster 

that's all I could figure 

Usually chevron 93 

so its weirdit's weird
