I have not adjusted the HSAB's (though on the carb they can be changed).

I guess this is trial and error as well?

Why not jet for each cylinder , dont have to run identical jets on the secs , same goes for primaries.

You ever heard a V8 on song , better than a 5 finger shuffle. :D

Get the pump shots dialed in right , correct P/S jetting , right plugs for the combo , correct spark lead , HSABs , right size carb..........................no need to faf around with timing.

Never thought I would so completely agree with you Adam. ;)

If you feel you have to use the high rpm retard could you not wire the 1st stage retard into a second tach switched via the shift light? , that way you can 'dial' in the retard @ any rpm.

The motor won't know whether you're in 1st 2nd or top , so if you think the retard is necesary @ a certain rpm then it won't hurt pulling timing out in any gear.

Just a thought.

You need to sort the HSABs first, then rejet for a flat A/F mix, then sort the idle bleeds if needed.
Choosing the right carb should have been your first choice ;)

What size Acc Pumps are being used, pump shot, squirter size, are they covering the the launch, before the main jets take over... do you have a spacer
All this is attributable to initial rich/lean holes in performance

Tis coming from you Steve , you ask me to check your plugs & give you a tuning window when running the gas , when the motor does'nt perform you argue i gave you the wrong jet spread & timing figure , how can you expect to run decent times with no purge solinoid? , i run good #s on the spray so must be doin something right ;) , maybe read you're own plugs next time out & see what you pick up.

The ONLY damage on the motor is a lifted land , caused by arming the gas in the water box , NOT a tuning issue , when you can pull a plug that looks like it came out the box then you're somewhere close. ;)

Every thing i post you argue the point , marbe sit back & have a think , did'nt realise my previous posting had to be in order , sorry , think were suffering from the same dillema goin by your previous post. ;)
