Just wanted to add Aux Venturi 4.5 Needle valve 2.0 Choke 36

Again I want to thank all of you contributing to my Weber education and hopefully I will pass. Here are the specs I have gathered so far: Main jets F16 Emulsion tube 145 jet 160 air jet Idle jet 60F8 Pump jet 45 As indicated these came off a running car and were synchronized on it and I have not altered that. The car had significantly more HP than the stock 240Z they are on now. The 240Z has 6 into 2 headers with a twice pipe exhaust, 280ZX distributor and if it matters an electric fuel pump. Is anything else needed to look at...?

I still have not made it out to the garage to pull off the jets and determine what they are, busy closing up the cottage for the season and will get back to the car in a few days. I will post the specs and would appreciate any feedback at that time.

Whiteheads, I know them well, dealt with them off and on from their startup but in this instance I would like to take a run at doing it myself first. The carbs came directly off a running car (L28)but as mentioned about 50 % more HP than this L24 so I was told that the jets etc would likely be too large. If it doesn't work out with me doing them nothing lost.

Sure, I will pull the rest of the jets. The car will not idle currently and feathering the throttle is required to keep it going. I have not driven the car with the current engine but I did test the engine with SUs before installing it. The 280z engine let go with a scattered #3 piston so I am essentially starting from a zero knowledge base on Webers and the current settings of the Webers. Thank you for the question so I will get to the carbs for that information.

I removed a high compression 280z engine which was probably in the low 200 HP range and transferred some of the parts. I replaced it with a stock 1972 240z L24 and the modifications are a ZX distributor, 6 into 2 header and triple Weber 45's from the engine I removed. My question is around the Webers. They were obviously set up for the hotter engine and I have bolted them onto the L24 and thought someone may have a "stock" configuration in respect to main jets, choke tubes, idle jet, air corrector jet etc. Current main jet is a 145. I have not had any experience with Webers but hope to be able to set this car up myself buying the correct parts.

After reading this thread I realize what I thought was a head gasket is very likely a manifold gasket on my 240. There is a very audible "ticking" and it increases as the car is revved. My question to anyone who has experienced this....will one of the effects also be a loss in compression. The car starts on the first turn, revs reasonably freely (noisy ticking aside) but when driving lacks acceleration or response.

I am curious if any other model year Civic wiper motor has been used. I have been looking for a wrecked 1991 Civic for months now without success. How about a 90 or 92/93 etc? Anyone used a different model year other than the 94 mentioned? Len
