I thought that (CVCC) was during the '70s, with pretty much all cars switched over to unleaded and cats. They're listed for '89 Accords.

ok so i have moved it back to about 10 degrees instead of 14 where i had it before. and it does run much better especially on the highway. so compression on the whole engine is about 120 per cylinder and about 95 on the 6th cylinder with the tapping noise. tapping meaning its probably the valvs. so it idles at 700-800 rpm and under load is abot 550- 600 rpm, is this normal? and it has good power from about 0- 30mph and even better power on the highway, it cruises at about 2700-3000 rpms on the highway going 60mph varing on the roads hills. so do you know if the rpm are ok at that speed. i drive about 20miles to school so about half hour on the roador more depending on traffic.

It idles a bit high....you might check for a vacuum leak somewhere. The noise + lower compression could also be a worn camshaft lobe. I think that engine has hydraulic lifters but you may be able to snug them up a bit. You can also sometimes clean them by adding a cup of automatic transmission fluid to the oil, then run the car hard and change the oil out.

so would a cam kit be a good idea right now or not. pull the heads and change everything out, valves and all. im going to try that trany oil thing u talked about. what it there is alot of carbon build up on the pistons and the heads. then what. clean it myself or take it in, cause yesterday me and my uncle bought a 63 chevy c10 and the heads looked like some one put mud on the pistons and alover the spark plugs. really bad. ok so my truck now, the idle is lower at around 600 to 500 rpm at idle and under load about the same just lower , man it run really good at night with that cold air coming in, is that how its supose to run during the day??? really ballsy with just regular gas from chevron. ive tested all other ones and chevron seems to last me longer and better performance out of it? Hey thank alot for helping me out. really do appriciate it> Ben.

I had an 8o Accord and later an 85. Both were capable of running on leaded fuel in that they didn't have catalytic converters but the last year that Honda had a filler neck that would allow the leaded gas nozzle in was 1979.
I believe they changed the filler neck due to federal regulations kicking in. That's what the Honda service guy said - at the same time he was suggesting ways around it if I wanted to do that.
