Jason Moyle Racing

Hi Andy...welcome aboard!

Car looks cool...fair bit of work gone into that...top effort.

If the chokes are still the std issue 36mm then the F16 tube and 145 mains should be fine. I'd back off the air corrector jets tho...155 will make it rich at the top end of the power band...id try 175's to start with.

The idles @ 55F8 could be too rich too...tho it depends on the idle screw positions.

Start by turning all the idle screws in, counting each half a turn. Then turn them all back out 1-1/2 turns each and fire up the engine. Turn one idle 1/2 turn back in and note the idle..if it goes up do the others the same...you will no doubt need to reduce or increase the idle speed while doing this if it races away or trys to stall. The aim is to get all the idle screws roughly in the same place within a window of 1-1/2 turns out each...if best idle is on less than 1 turn out the idle jets are too rich...more than 2 turns out and they're too lean.

When you drive on part throttle your driving on the idle jets...too rich or too lean and the response to gentle throttle use will be pants. It sounds to me like it's too rich...50F8's could be a better option or even 45 F8 or F9.

You also need to make sure the carbs are balanced...either use a proper balance airflow measure or a bit of heater hose and listen too the middle 2 trumpets...the "hiss" needs to be the same...again idle speed will need tweeking while doing this.

Check your timing off the correct mark...it's not the v groove or raised square boss...get number 1 piston to true tdc and look for the little dimple in the flywheel...thats the tdc mark...set the timing light to 8 degrees and line up the dimples with the arrow in the gearbox case timing hole...don't use the front pulley as they twist on the rubber damper with age putting the timing mark out.

Have a go at that first.

What filters are normally used?...if it's foam socks throw them away. Also...you'll need a shield in front of the carbs...direct air being forced into them upsets the signal to the auxiliary venturi and buggers up any settings at speed that may be fine at idle or on a rolling road.
