valve springs!

could they wear out from just sitting in my shed for a year ?

Personally
I'd go BP7ES or EY if you can get them (non resistor)
Get the dizzy graphed for no vacuum if thats how your running it (Shultz auto electrics in willetton will do this)
Make sure the coil is right for the rest of the system (mine had the wrong coil on it once and it wouldn't rev... not enough fat spark)
Get the fuel pressure reg and gauge in there to make sure your fuel requirements are set


Then rev the tits off it

wrong springs? wrong installed height?
restrictive exhaust?
or any of the other stuff above
what did you pay the tuner to do? HE should be telling YOU whats wrong!

1) do a compression test ,if the comps down you can F#ck around all you like and get nowhere
dazza

try putting your foo further down, you get scared by it dont you LOL!

thanks dattoman_1000 ill get on to that dizzy guy :) and get them plugs n coil :)

what did you pay the tuner to do? HE should be telling YOU whats wrong yes i rang him and he said coz i had my shift light set to 5500rmp he only tuned it to that rpm and it was fine but i only had it set to that coz it would back fire so he isn't too helpfull and he charged me for cleaning the webbers after i told him there rebuilt so no help there and i will look for someone else to tune next time

the exorst is 2.5inch but one extractor had to be dented to go around the steering idler arm but wonce again was like this on andys setup and reved fine

and wrong springs? wrong installed height? i expect all this to be fine has this is how andy ran it

So the only things that has changed from andys setup to your setup is how and how much feul you get to the motor and how the motor is getting spark. Get those 2 areas checked out and should be smiling all the way.

and the rebuilt webber im hoping the guy didn't change the jets or choke's :?

edit ; you tube
heard the car in action last week , cars mainly reving between 4000-5000

Jordy, I honestly believe the problem is the spark plugs. The R for resistor means they were decreasing the voltage for the spark, which was probably being washed out by the fuel. Not your fault, as that's what was recommended to you by the 'tuner'. I second the NGK BP7ES or EY plugs. I'd also recommend you take the resistor plugs back to the 'tuner' & stick them up his .... Honestly from what you've said, he doesn't know the A series engine. Sounds like the guy in Newcastle who rang my engine builder friend saying the VW motor my friend built only made 44 hp at the rear wheels. As identical engines have been dyno'd at 120 hp at the rear wheels, questions were asked. Turns out the dyno operator only rev'ed it to 4000,not the 6000 that it should have been rev'ed to. The operators response was that he is only legally allowed to rev it to 4000 without the owners permission. Maybe the 'tuner' in your case thought that was all you wanted it rev'ed to. if the engine blows up & the operator has rev'ed it higher than you've told him he can,he is liable for any repairs.
