First off,Thanks for all your help guys.With some coaching from Steve from ZT.I got it right.She runs as smooth as silk.I had the choke cable set to high.that was causing a mis-adjustment in my carbs.Then I had my collector pipe, were it connectes to the exhaust pipe welded...no more popping!!!yahoo..So to every one that put in 2 cents worth..Thank ya,Thank ya,Thank ya..Now how about this one?I have a fuel smell in side the car.I see no leaks.That I can see.So fire away with your opinions.....oh ya, I see alot of different settings for spark plugs NGK,s that is.Im going with BPR6ES.Set at .40 ???????

I smelled fuel in my car until one day working on something else I had the hood up and turned the key so the fuel pump kicked on and noticed fuel squirting out of a fuel rail to carb 1/4" hose. FWIW.

Ya Mike,I thought it might be a leak to.But I have checked every place I can and see no leaks at all.After more driving today, it seems to be the carbs.But it runs so good at this setting, I dont think that it is.And when I lean it up it starts to sputter.hmmm

Is the fuel smell with a full tank of gas?

i have FI so its different, but i just want to point out that i had a huge fuel smell also. and could not for the life of me find the leak. it was on the fuel rail. one of the hose clamps were lose and fuel would come out and puddle on my heat sheild.. and the only reason i found this out was i had my gf turn on the key while i looked at the engine, and when the fuel pump kicked on i saw it barely drizzle out like it was very small, but because it puddled i got the bad smell.

The cause of the fuel smell in my S30 was a old perished vent hose from the tank to the filler tube. It had gone where the hose enters the rear deck which is covered by the rear internal plastic light cover.

Pull the rear interior hatch covers in the boot and check the lines and replace where necessary. Remember to use fuel rated hose as the vapour will eat normal hose.
