Have you tried squeezing the bulb at WOT, maybe a weak fuel pump.
Lines might be blocked, has it got a fuel filter as well?

Maybe a vacuum leak but typically it doesn't just happen when you open it up, it would run like a dog at idle. Idle would be lower if vacuum were an issue.Have had the carbs out and put a kit in them?

Re: no power at wot

do you mean rebuild the carbs?

Re: no power at wot

You said carbs are clean. Carbs are clean when they are cleaned and a new kit put in.

High speed jets may be clogged

i'm gonna clean the carbs. I am also going to check for air in the line, If there was air in the line, would't all speeds be effected?
