The dashpot is simply a damper which slows the rise of piston and causes a temporary rise in air velocity in the venturi which in turn results in a temporary rich condition or accelerator pump affect. The normal throttle stops adjust how far open the butterfly is at idle but there is still a stop for the piston and adjustment of the needle height. There will be something that adjusts the position of the piston and needle at idle so if it wont idle its either that adjustment or the enrichment device. I installed an electronic fuel pump, changed the spark plugs, oil and filter, changed all the fuel filters (the one in the sump had broken up and the sump was filled with debris), and when I turned the key it started right up.īut it seems like it is running very rich and like I said blowing out black soot and smoke.How much oil should go in there Presumably too much will not allow the piston to rise properly Thanks.Īt idle the piston shouldnt lift at all and therefore the diaphragm has no effect. It turned over but wouldnt start and I heard no ticking coming from the fuel pump. I brought it to a local restorer who worked on the body only but then went out of business this year so I took the car home. When I bought the car 6 cars ago from a local person who had it just sitting in his yard with no hopes of restoring it, it took forever to start and ran very choppy. They should not be split, although I think that would cause weakness not soot.

The diaphragms are the rubber things you see when you undo the four screws and lift the top from each carb.

John, would it say in the manual where the diaphragms are and how to check and replace them This car is new to me and Im learning things on the fly here That would make sense that there is something else serious going on causing the thick, black, sooty smoke because when I turned the idle mixture trim screw nothing happened.Īre both tailpipes equally black If you have the ignition on but the engine not running do the carbs drip fuel Assuming the car ran until it was laid up, its unlikely to be float height trouble. The idle screw on the side of the carb seems to be there to compensate for new engines which may not idle as required with the stock setting. Later cars used the B1AR needle.Others needles are available such as the B1AF ( original fitment for the TR6 ) which will give a quite lean mixture, and the B2Y which is a bit richer. However.there are ways of getting around this - 1 ) fit a different needle.Įarly 68 cars used the B1E which was quite rich at higher air flows.

Have you checkedreplaced the diaphragms Automatic idle speed is 650 rpm with the selector in Neutral.Ĭars with the Strombergs fitted are much more common Stateside and you will find enough info.ĬD 2 was fitted to cope with the emissions regulations and was designed to be set-up at the factory and not tampered with by owners, so adjustment of the mixture is not possible. Its an automatic and one book I have says to set the idle speed at 500 and another says 650.

See Datsun page for full details on rebuilding and conversions from flat top to round top conversion kits. The air pistons are checked for equal weight drop times within the carb body assembly.Ĭompare the amount of NEW parts, the amount of labor in testing that is included also the finished is next to NONE. See the Micropolishing page for details on the Micropolishing process. This includes the suction chamber air piston slides which are very important for NEW factory operation.
