grunta Posted May 2, 2017 Author Share Posted May 2, 2017 so the carter carb i have has a hose connection on top on the accelerator pump , is this just a breather? Quote Link to comment Share on other sites More sharing options...
cletus Posted May 3, 2017 Share Posted May 3, 2017 Probably something emissions related? Ie a breather to stop fumes escaping. The aussie spec ones ive had don't have that bit 1 Quote Link to comment Share on other sites More sharing options...

1963 AP5 Posted October 27, 2017 Share Posted October 27, 2017 I think it is very unlikely that you are over-carbed with a stock style 2 barrel on a slant 6 and the fact that things are OK at wide open throttle suggests that the carb size is just fine for your engine. Maybe try running it with your vac advance disconnected and the port on the carburetor blanked off or even try knocking the timing back a few degrees. Slant 6's make a fair bit of manifold vacuum and at part throttle you will almost certainly be pulling vac advance . This could be contributing to the part throttle problem while at wide open throttle the vac advance shouldn't be active. Not sure if it will make any difference but it's very easy to try.

grunta Posted October 27, 2017 Author Share Posted October 27, 2017 Funny you mention that as It did run much smoother when I knocked off the tube and didnt realise ... had a vac leak too and was smoother... initial timing has been played with and im set around 8'btdc and it looks to advance to around the 30-35btdc mark under full throttle ... (thats just in the garage not under load... ) ive been to both exrtrams of initial timing 2-12' and it made little difference .. is it a known problem with the vac advance causing thibgs ljke this because it would make sence with the symptons... ? I will definitely try it... any idea on what the mechanical advance will advance it to by its self? .. .. also went for a massive drive this morning which was choice .. I really dont drive it at all above 1/2 throttle anyway so it really isnt a problem... drove nice tbh Quote Link to comment Share on other sites More sharing options...
cletus Posted October 28, 2017 Share Posted October 28, 2017 One of my cars in the past I had to block off the vac advance because of light throttle bag-o-dickery, it would start surging. That had a too lumpy cam though. ling. jpg Quote Link to comment Share on other sites More sharing options...
1963 AP5 Posted October 28, 2017 Share Posted October 28, 2017 I know fouling of #6 can be a symptom of timing issues. 6 runs hottest and can be prone to pre-ignition/poor combustion if the timing curve is not correct. Vac advance modifies the mechanical advance curve and if it's pulling too much in the mid range maybe it's contributing to the problem. Like cletus I have had to disconnect the vac advance on a modified engine because it just wouldn't run properly with it connected, that engine also carbon fouled #6 and that's actually what prompted me to suggest disconnecting it. 1 Quote Link to comment Share on other sites More sharing options...
grunta Posted October 28, 2017 Author Share Posted October 28, 2017 Awesome thanks I guess I could then run a little more initial timing Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted October 28, 2017 Share Posted October 28, 2017 Something to check is that it hasn't spun the damper. That will give you an erroneous baseline. 1 Quote Link to comment Share on other sites More sharing options...

grunta Posted May 1, 2022 Author Share Posted May 1, 2022 If you have a spare 1 that would be cool Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted May 1, 2022 Share Posted May 1, 2022 Its keyed, so that part doesnt move. What I've seen happen on slant 6 before is the outer ring rotates on the rubber ring causing the timing mark to be out of whack. 1 Quote Link to comment Share on other sites More sharing options...
grunta Posted May 2, 2022 Author Share Posted May 2, 2022 im gona get new timing chain and prob replace the harmonic balancer anyway but will degree it before putting her back in ... engine is going to get a bit of a sweetee up and full tranz rebuild... 1 Quote Link to comment Share on other sites More sharing options...
