87 Saltaire engine stunting /dying at 3500rpm with full throttle

[lively]

what is your timing ?

Take the anti-syphon valve out of the fuel tank, replace it with a regular 90 and give it a try.

Adjusted timing and fuel mixture on carb and now much better. Still missing a little but so much better. Will check spark plug gaps also. Thank you guys. I thought the timing was right but was a little to advanced.
