Yes but you need to limit the vac advance to 10°btc and get the mechanical advance to 20 to 24° and all in by 3000 rpm

Thanks. Is that hard to do. Or should i just get get a new one without the vacuum advance on it.  They are not cheap though

[454Man]

Not hard I let my little girl 11year old do it last time
