I'm trying to time my 1.8 with carbs, and am having a rough time. I'm not sure if I am suppose to have a vacuum advance or not on my dist. Anyone know if the dist on my car is stock, or if it's an "upgrade". If it's an upgrade, is it any good?

I ordered a new condenser for it, and the one I ordered didn't seem to be right (original had a separate bracket that held the plug in - replacement had the bracket attached to the condenser). I believe that I had to mount the condenser upside down for it to fit properly (as it was originally). If the condenser was mounted in what seemed to be the proper position, the dist would not fit back into the engine properly.

Terry,

You have an aftermarket bosch "009" distributor. Some say not a good version to use on the type IV others use the 050. There are differences in the total amount of advance and advance curve between the two. However, you can get your engine to run OK...as a starting point try timing the engine with a total advance of 30-32 degrees at 3,000 RPM. "power timing" this way gets the distribuotr advance in all the way in. You'll need an adjustable timing light using the TDC mark on the cooling fan. Dial the timing light to 32 degrees run the engine at 3000 RPM and set the distributor on the TDC mark.

Always be sure to have your timing correct prior to adjusting your carburetors.

I'm sure others will have a comment on this...

Kargeek,
Thank you very much for that explanation! I've been going back and forth from different sources, trying to figure out exactly how to time my engine (I don't think I really understood what was meant by "advance"). I'll give that a try tomorrow.

Thanks again! (IMG:style_emoticons/default/clap56.gif) (IMG:style_emoticons/default/clap56.gif) (IMG:style_emoticons/default/clap56.gif)
