Hey everyone I have just bought another 70 and the young whipper snapper I bought it off threw a 32/36 weber on it with extractors he told me he had it jetted to

140-160 air jets

135 and 150 mains

but it still hates -3000rpm unless foot flat down. Now I know the weber is to big etc, I do have an aisan carb but this young fella has screwed around with most of the vacuum hoses so I wanted to leave that to a last resort.

I have found these jet setting for a kp61 4k with a weber does anyone know if this sounds good?

Just really wanted to try to get this clarified before I spend more money that won't get me anywhere

 

Idle Jet: 55

Primary main jet: 125

Secondary main jet: 150

Primary air corrector: 180

Secondary air corrector: 150

Have a look through here. Not sure if it will help, but may give some guidance
