After a complete tune-up and adjusting the SU's on my stock '72 I am now experiencing a backfiring sound coming out of my exhaust when I decelerate (cruising at 40mph, let off the gas & leave it in gear). The carbs appear to have the proper air/fuel mixture as per the tip of raising the valve 1/16th of an inch to hear a slight RPM increase and then return to normal. Vacuum tests are showing great results (steady needle 'in the green') and I have steady power under load without a backfire. Idle is steady at ~750RPM and the SU's are synchronized. If I lean the SU's out anymore than I have right now the car boggs down during acceleration. Any suggestions on what to…

I'm putting my L28 back together after replacing the rings, bearings, valve stem seals, etc. The engine had two bad rod bearings which is why I pulled it apart. I had removed four of the cam towers to get my valve spring compressor into position. I kept track of where they went for reassembly. I've got the towers back on and the cam in place. I left the towers loose while I slipped the cam into position. I can tighten all the towers, except the back one (#5). If I tighten #5, the cam wont rotate. If I leave it loose and tighten the 4 others, the cam rotates smoothly. I played with feeler gauges and found that if I put a .04 feeler gauge under the #5 tower and tighten it, …

Bought a timing Gun and found out theres no timing mark on my 77 280Z > . Am I missing something and where is the engine ground to connect the Black Clip of the timing Gun to? Was told my timing is 4 degress and it should be 10 according to the smog guy. It's 6 degress off. Motor is L28 build date 10/76 4 speed. I'm hopping getting the timing right will let me pass smog. The Hydrocarbons are 2,000 when it's only allowed 150. Below is a copy of my failed smog test. The Smog guy "said" the catalytic converter is fine. I dont knowhow he camt that conclusion since all he did was stick a sensor up it's pipe. Please help if u can. Thyanx ~Z~

Question : can I seal my vacuum hose leading to the bad brake booster and effectively re-tune my carbs? my Z ran good with my self installed Z therapy carbs.... before the booster failed...now I hear air leak when applying breaks (diaphragm maybe)...also idle drops to stall when braking... I tried adjusting the carbs to remedy the situation to get the car in for booster replacement and now I've got a non-starter. I've reset my carbs with mixture knobs all the way up and back down 2.5 turns and get nothing better than bogging from the throttle application until engine reaches 2,200 rpm. (runs great above) but no response from the throttle under that...just bogging. …

We have been working on rebuilding a 1973 240z which we recently purchased and came across another puzzle that I was hoping someone else had experience with. We recently got the car running and took it for a test drive. After driving about five miles we stopped for anoint half an hour and then took off again. Almost immediately the car would buck and shudder any time we tried to accelerate. For a short time it would idle but then shudder and die under acceleration. We ended up towing it home. My initial thought was that the fuel filter was bad. We added some gas to the tank (just in case) and put some Heet in the tank. We then pulled the fuel filter. It did not look dirt…

I'm trying to remove the A/C belt. I have loosened the tension pulley, but the bolt just keeps backing out and the tension will not release. The bolt I loosened is pictured. Am I loosening the right bolt? I've tried tightening it, but it didn't seem to have an effect, maybe just tighter. Ideas? Thanks

Today, my Z started making snap, crackle, pop noise out of the exhaust. It's spewing a lot of exhaust as well. This is my first Z car and I'm a newbie when it comes to mechanics. All I know is that the car has the stock engine with twin carbs the previous owner installed and I'm not sure who's the manufacture or model. Also it won't idle in neutral as well. When I take my foot off the throttle it, it loses RPM and dies on me. I'm just wondering what's wrong and I want my Z purring again! Having such a beautiful car and having not working properly really bums me out. I hate having to hear my car sound like Rice Krispies! I like staring at it, but I'd love to drive it! I k…
