same gap as standard. unless the plug makers states differently.
Also what do you mean by High compression?

Atm I don´t know my engine compression and will be the next step to see on my car. I am running too rich with a single hs4 and really dont know the problem.
High Compression was 160lb when I once had done it

When I had my MED 1380 set up on the rolling road by Peter Baldwin I was advised to run standard BP6ES and standard gaps if using a normal electronic ignition system. He said only open up the gaps if using a megajolt type setup.
Thanks a lot for the advice, so I will use champion N9Yc or NGK BP6ES

You should find the NGK BP6ES will be better.
Electronic ignition is not as fussy about plug gaps, 0.035" should be fine.
What makes you say it running rich ?

This allows me to say it is far too rich

If it is running really rich then possible issues on HS4 are:
- main jet not returning fully up when choke pushed in
- float chamber needle jet not sealing off
- incorrect main jet level
- worn needle (swing type)
- incorrect or modified needle
- badly clogged air filter

hard to tell as you cant see the important bits. need to see the sparking end and the ceramic.
that is just a picture of a dirty spark plug. Sorry.

I can check it out again if you want to, and also was thinking of buying some new ones, but would like to do some twerking on my carb to get it perfect
