Hi All I am having this issue with a Thermoquad but assume that the method for addressing it is similar for any carb using metering rods. I have done some searching (maybe just not hitting the right keywords) and have not seen much on this topic. If there is a thread I have missed, please...

Hi All I have a Thermoquad (made from two parts carbs). When building the one good carb, I used the 1 1/2 throttle plate as it was in far better condition that the 1 3/8 plate. Not paying attention, I used the 1 3/8 bowl on this combination (Looking back at this, both carbs had miss-matched...

Hi All I put this jet/ rod calculator together to help me better figure what affect a given rod or jet change on a thermoquad may yield. Primary calculations are relative to the jet/rod area difference. I know it is common to substitute Edelbrock rods for "stock" metering rods, at this time I...

Is this brass float built right? It seems like the hump on the brass float should face up towards the top plate. I have only ever delt with nitrophyl floats.

Hi All I have ran an electric fuel pump in my car since about 15 minutes after the engine was fired for the first time. The reason was that the mechanical pump that was on the engine had a faulty diaphragm and pumped about 1/2 gallon worth of gas into the engine. When this happened i figured...

Anyone using a 3/8 fuel inlet in stead of the 5/16 one? If so where did you get the parts from ex. Napa, Summit,tubes n hoses. I see I can get stuff on the internet but would really like to not have to pay shipping on a 4 dollar part. The carb side of the fitting is a 5/8 -20 with Banjo seal.

Is any one using a vented gas cap on thier olders cars. i have heard of people using them but have yet to see one or find what cap they are using. I have a 74 duster and id like get rid of the charcole canister and that extra vent line.

I am getting ready to install an electric fuel pump on my 74 duster. The instuctions for the pump strongly recomend a oil pressure shutoff switch. I guess this is so if the car stops running while the igniton is on the fuel pump will shut off. Is it worth it and what do you do about your stock...
