Johnny wick Posted March 6, 2018 Share #229 Posted March 6, 2018 2.5 turns clockwise front and rear carb after cranking and running the engine for 1 min. I dont see no 1/16 inches of gas? Do you see it Link to comment https://www.classiczcars.com/topic/47304-1972-float-adjustment/?page=20#findComment-543947 Share on other sites More sharing options...
Mark Maras Posted March 7, 2018 Share #230 Posted March 7, 2018 Nope. I'm not surprised. Try shining a light down the nozzle and try to determine how far down the fuel is. You could also try using the small tube from an aerosol can like WD-40 and try using it like a dipstick to determine the depth. One way or another the distance from the float to the lid has got to be reduced.

This right here. The troubleshooting has just been going around and around in the same loop. If he had done this from the start he'd have had his car running well over a week ago. You guys are being real good sports stinking around, kudos. Carbs look nice and clean though, once you get this all sorted out... should run well!

Johnny wick Posted March 7, 2018 Share #232 Posted March 7, 2018 Ill have to lower it more car is still backfiring and sputtering under 4 turns clockwise. I really dont trust to pressure of this airtex 8012sx fuel pump. In the past when i the pressure was 4.3 psi the fuel filter was always full even after the engine was shut down.

Mark Maras Posted March 7, 2018 Share #233 Posted March 7, 2018 IGNORE the fuel filter. The fuel level is fine. Trust me. I've seen lots of them this way, including mine, which ran fine half full for decades. IGNORE the backfiring and sputtering. Until the floats are confirmed to be set properly, set your nozzles back to 2 1/2 turns down. RESIST the temptation to fine tune with the mixture screws until the floats are set. FOCUS on getting the float level 1/16" below the nozzle tops at 2 1/2 turns down. You can't compensate for a wrong float setting with the mixture screws. It doesn't work. If the fuel level is wrong, it won't be at the needle idle stage and will continue to be off throughout all RPMs. Link to comment https://www.classiczcars.com/topic/47304-1972-float-adjustment/?page=20#findComment-543958 Share on other sites More sharing options...
Johnny wick Posted March 7, 2018 Share #234 Posted March 7, 2018 Ill have to keep on adjusting the gap Link to comment https://www.classiczcars.com/topic/47304-1972-float-adjustment/?page=20#findComment-543967 Share on other sites More sharing options...
siteunseen Posted March 7, 2018 Share #235 Posted March 7, 2018 Has this car ever ran right? I can't remember hearing that from the owner and I've been on here since 2011. 1 Link to comment https://www.classiczcars.com/topic/47304-1972-float-adjustment/?page=20#findComment-543971 Share on other sites More sharing options...
240260280 Posted March 7, 2018 Share #236 Posted March 7, 2018 Panama is very hot so this car will have challenges most do not have... except maybe Texas, New Mexico, or Nevada in the summer.

Johnny wick Posted March 7, 2018 Share #237 Posted March 7, 2018 Thanks for your assumption. You are fully correct. 4 years of having purchased the car and still does not run as it needs to.

Johnny wick Posted March 7, 2018 Share #238 Posted March 7, 2018 Maybe ill need to pay a plane ticket to one of the experts in the us to see if they can get it running correctly at high rpm and under heavy traffic at idle.
