Ever since i bought my B20A which has some unknown spec cam regrinds its been loud as fuck in the cylinder head. pretty safe to say the valves needed adjusting so i pulled out the manual today and set them accordingly. but when i was done i started it up and fuck it ran like ass. Wouldn't idle so i turned it up to 1500rpm and it idled rough as fuck and it didnt make much power till like 4500rpm where it went hard to its limiter. (7k)
Do the specs need to be different for the different cams?
I was unhappy with the car so i waited till it cooeld down and got a bigger feeler blade and reset them to a bigger gap, Now Its quiet and makes really good power all through the rev range. All thats fine yet it idles at 1000rpm very unstably. sometimes it will stall.
Any ideas? were the valves set at a big gap when i got them for a reason?
