irokin Posted September 4, 2011 Report Share Posted September 4, 2011 No matter how much spark you give it, if there is insufficient oxygen to complete the combustion you will have unburnt fuel exiting the exhaust. No witchcraft going on here, just simple chemistry. Likewise with extractors, you're still going to have the same/similar ratio of fuel/air just perhaps more of it. Address the issue directly ;) Quote Link to comment Share on other sites More sharing options...
t18drifts Posted September 5, 2011 Author Report Share Posted September 5, 2011 so re jeting then aswell as spark Quote Link to comment Share on other sites More sharing options...
GJM85 Posted September 5, 2011 Report Share Posted September 5, 2011 (edited) There are all soughts of possible issues with the twin solex setup you will run into. You need equal fuel distribution and pressure. Ditch the inline fuel delivery and make up a T section delivery. Get a fuel prssure regulator. They run around 3 psi. Not a great deal of people know anything about sidedraft solex carbs. Parts/jet kits are harder to source than dellorto parts. Bits get loose over time (venturies). You should run tube headers with or without the twin carbs. At the end of the day don't do what I did and try and make it work yourself. As stated 'witchcraft' no worky worky. Bolt them on and get it to the tune shop... I gave up on my Type T solex setup because I realise now that I went completely the wrong way about it.

Redwarf Posted September 5, 2011 Report Share Posted September 5, 2011 Put another/ bigger return spring on your lingkages/ butterfly shaft. If it hasn't been dyno'd, they'll be about as much use as a bicycle to a fish. Dyno will solve all. Or at least tell you what you have to do.

19914afc Posted September 6, 2011 Report Share Posted September 6, 2011 The solex carbs are alright but like said above harder to find parts for and not the best carb available, I had them on my car jetted for a slightly bored and worked 2TG and they where OK on my 3T just gave them a tune by ear with a piece of hose and it ran alright but kept getting an air leak because of the manifold I had on there so just f@$ked them off and put a simple single 38/38 weber on.

TRD ke70 Posted September 7, 2011 Report Share Posted September 7, 2011 If you have had the float chambers apart, just check to make sure you have the choke disc's lined up properly before you put the tops back on. Common problem is that that get lined up wrong and the chokes are on all the time. Quote Link to comment Share on other sites More sharing options...
snot35 Posted September 7, 2011 Report Share Posted September 7, 2011 If they're not closing properly make sure everything is completely flat. If you have twin carbs then the spindles should be near to exactly in line and not binding. If they aren't then they might not shut properly. To do this make sure everything makes lines up properly. Both the bottom and top faces should be parallel to the manifold and in line vertically. Weird slow rev down might also be an air leak or mixtures.
