Yeah you might be right

Ok so I have an update. Jumped under the car this arvo and sure enough, I must not have connected the vacuum line to the trany all those years ago. So then, with full confidence, I turned the key on and sure enough POP POP POP. The trany shifts up no problem now though!. That's one problem sorted! The idle was alot lower after connecting the hose though. I have wound the idle near all the way in and it's still a bit low. The idle also keeps changing day to day, even minute by minute!. I will get the idle good and then 10 mins later it's way high so I wind it down and then 10 mins later it stalls. I must still have a vacuum leak somewhere? Will I need to try timing again after fixing some of these vacuum leaks?

Yeah it has bright red fluid and is probably to full if anything. Not sure if it smells or not. I will check this arvo! Along with the vacuum hose. Thanks!

Yeah it no doubt is perished on this old thing. I will check it out tomorrow arvo!

Hi, no just checking the ends of the lines. Ie. The dizzy vac line at dizzy end.

Thanks Bear! I have just finished playing around with it again. Seems to run well at 10 deg, so I have left it at that for the moment. I just replaced my thermostat housing and found a little vacuum line off but still popping. I tried spraying some aero around the intake but didn't notice any change in sound. The weird this is though, I sprayed it in the carby and only noticed a slight change in noise anyway. Forgive me for not being all that knowledgeable with these engines (its why im here) but I traced out some vacuum lines and noticed that one goes to the transmission. With the transmission, it has always struggled to shift up. You have to rev the guts out of it and maybe it will shift. Isn't there some sort of vacuum modulator or something on a 3 speed C4 trans? (The trans is out of an XC Fairmont that I threw in about 10 years ago with my father). Also, when I pull a vacuum line off it seems to make not difference and when I spit on my finger and put it over a vacuum line, I can't feel any vacuum at all. The vac advance seems to be working with the timing though. I'm wondering if there is just a vacuum line dangling next to the trany now and I just had a shower

Yeah no worries I havnt tried that yet. I will have a look around with the aerostart this arvo. Wouldn't surprise me if there is a vacuum leak as I have had to repair 4 different split fuel lines. When you say just twist the dizzy to get the idle, do you mean until it idles at its highest or just till it sounds about right? I have the idle screw in a long way atm with it at 6 deg. Should I wind it back out and just advance it till it sounds good? Thanks!

Thanks! Had a read through and watched the vids. Little bit different from my issue I think. In the video, the engine seemed to be delayed and not very responsive. Mine is very responsive to the throttle but just makes an awful POP out the carb when I push it or at idle.

Hi, yes I set the timing at 6 deg btdc but I originally set it at 10 deg btdc and changed it thinking I may have had preignition. I will try and advance it to about 15 tomorrow afternoon. You are probably onto something with the diaphrams in the carby . This engine has not ran right for at least the 15 years I have owned it. I have read some forums suggesting maybe to much fuel flooding in on idle? I would appreciate your thoughts. Thanks!
