I took the carb off again as I’ve played with so many adjustments. The transfer slots on primary’s and secondary’s are covered. I opened the back one 3 1/2 turns to get .020 and the primary I opened the idle screw 5 1/2 turns to make x pose the transfer slots. The air bleed screw under the air clean...

Transfer slots are fine and secondary blade adjustments
This carb was brand new and had problems with it running rich sent it to mark and he did some work to it but it still runs rich at idle and the previous carb did same thing on this motor

I’m going to take 2 degrees of timing out at 3300 rpm
As not sure 40 degrees timing will cause denoation on 94 octane pump gas . At 40 degrees it is not as rich at idle.
By srewing in the air bleed creates a stumble if u hammer the throttle

I just went from ngk6 to ngk7 as the 6s were totally black

It’s idling at 1200 rpm
It has a electric fan, water pump and radiator but electric fan isn’t turned until after a pass
Msd 6al plug gap .035 NGk 7

Car won’t run at 1/2 turn out, runs best where it is also screw them in anymore it will stumble

I couldn’t see. What the purpose of the gasket was as the tin plate blocks all the ports anyways.
Jw told me to use the gasket and if I put in one of there billet supports then you didn’t need the gasket. I guess I’m still learning how the flow gets to the reverse piston

I have a jw pg and my question is I’m rebuilding it and curious on the gasket to use on the rear governor . Little info on tranny it has a pro brake and the rear govenor support is the stock cast one. So first install gasket then tin plate and then govenor support. The over haul kit has two gaskets ...

I have a 422 ci sbc with AFR 235 heads Cam is 106 lsa 271-280 750 lift, super victor ported , 950 dominator , 11.28 Cr headers are equal length 1 3/4 tubes with 3 inch on pump gas 94 octane . On the dyno made 659 hp. We tried 1 7/8 headers x 3.5 made 1 more foot pounds of torque . Don’t see a proble...

Update Sent torque into get checked, he phoned me back and told me torque was fine but found silver metal filings in the torque . I hauled the tranny out to the bench and first I did was inspect the input shaft. Right away I noticed on the input shaft on the end by the oil hole closest to the torque...

Carb has jet extensions and yes converter not right

Just started working on the car and was going check resistance on wires and check rotor and cap when I was pulling the rotor off the distubtor moved some . I said to myself hum grap the distubtor and tried turning and it moved . The clamp to hold it down has to be all the on the distubtor and it was...

Does the motor seem to be making rpm faster now since the rebuild, if so you may be revin thru the power band too fast making for the ET loss , but that being said your mile per drop has me concerned. Did your fire up the freshened up motor with oiled up cylinder walls , or dry They should have bee...

Yes I do
