Moz_Goodwood 0 Posted October 15, 2008 hiya all I did a twin 40 weber carb coversion to my 309 1.9 8v a while ago now but never cleared this up properly. on the inlet manifold there is two 'outlets' that suck air in, the left one (as you look at them) ive attached to the master cylinder but im not sure what to do with the right one does it need to go to somewhere as just leaving it open is worrying me slightly if its sucking in cr@p (because its bypassing the filters) or can i block it off? if so can you get proper blanking plugs?

MrG 3 Posted October 15, 2008 well mine is the take off for the distributor, so mine is plugged into that (well it was plugged into the TB when injection was fitted. other than that, plug it otherwise its sucking in fresh air? Share this post Link to post Share on other sites

pike_1.9cti 0 Posted October 15, 2008 I took 2 bits of pipe off the left and right hole joined with a T piece and ran it to MC. I don't use the vac advance on mine, not needed with carbs. Share this post Link to post Share on other sites
ericdean 0 Posted October 16, 2008 On my brothers 205 the 2 take off's have been joined together and then used for the master cylinder. Cheers Eric Share this post Link to post Share on other sites

MrG 3 Posted October 16, 2008 (edited) ah, good call, I'll do the same then, it was there before so just put it back!. In order to connect mine I used a L piece and new piece of pipe (washer tube), heated it in hot water and pushed it over, seems to work ok though!

boombang 2 Posted October 16, 2008 I unscrewed it on mine and filled it with weld. Put it back in with some silicon sealant on the threads. No air getting in there now. Share this post Link to post Share on other sites

vickiw106 1 Posted October 17, 2008 i have just had the same problem The best way I found was to take the union from your standard manifold (there should be two on a standard one) Use one for you mc vacuum and the other one fill the pipe/union with chemical weld/putty and before it has time to set get a pot rivet insert it into the hole. This intern creates a superb seal and if you do it correctly looks good as well I will see if I can get some pics of mine tomorrow Hope it makes sense Share this post Link to post Share on other sites
