Changed dissy cap rotor and plugs but giving like an over boost effect at high revs however also under load.
Also checked Timing and is 12 Degrees BTDC.
Had new Grp A Head gasket few weeks ago and head checked and skimmed.

Any ideas on this one?

 

Any ideas people? Please

 

more info - spec, when it happens, what does boost gague do etc.

 

get it set up by an expert

 

Cossiecrew, to be honest plan is too. But i'd at least like to have her running half decent before it goes any where.

In regards to spec.

Exhaust and filter only guys.

 

Rick i'd say a little hard to explain to be honest. She has had the amal valve D/C'ed may connect that back up tomorrow .

 

Right ok
1 - 3 psi
2 - 9 psi
3 - 9 psi
4 - 9 psi

Fuming is an understatement. Just had the head put back on.
Was skimmed, torque down correctly, pressure tested. Valves were not removed when the company skimmed head.

Can my Felpro be re used as it has only done 50 miles or so or would you say new gasket.

It can only be a valve problem?
