Hello. Just one question for now actually.

Ok, the origional service manual says that the timing should be 18 degrees. Is this with the vacume advanced connected or disconnected?

I've debated this with my dad (who is an old-school car kinda guy). Honda does NOT leave steps out of the manual, so in my opinion, you always time it with everything connected. I've always had the best results on my cars that way anyways. They seemed weak and hesitant with it timed w/ the vacuum disconnected.

Thanks for the reply

Ok, another question. I was wondering what kind of spark plug would be the best. My exhaust kinda smells a bit rich and Im thinking its due to incomplete combustion.

I usually just run what's recommended. Some sort of NGK. Should be on your hood, valve cover, or upper timing belt cover. If not, find an auto parts store that sells NGK plugs and they'll have the recommendation for you.

Thank you. We ordered the correct plugs. Theyre special order so we probally wont be seeing them for a few days.

The Factory Service Manual says to leave ALL vacuum lines connected when timing.

I like to use Bosch plugs with the four electrodes. On the old Hondas, the plug goes in at an angle and it is possible for the electrode to be pointing away from the center of the combusion chamber. Not a problem with the Bosch plugs.

Check your old plugs for their color. They should be a coffee-with-milk kind of brown. Darker is too rich, lighter is too lean.

I put the new plugs in a few days ago and i noticed that it ran better and even seemed to have a little more power.
I've seen the bosch plugs before. They look like a good design but i figured it would probally be best if the plugs that the car called for were used.

The Bosch plugs were invented well after your car was built.

Yeah, I'm well aware of that. Another thing is, the factory plugs are the correct heat range. Do the bosch plugs have specific heat ranges for different cars?

yes
