that won't work with a lot of duration cam an nobody knows what he has , only works with a cam has vacuum at idle, a square roundy round cam you will have him at over 20 degree's inish an who knows what mech an if he using vac can , this is a go through the steps isolate one carb tune to that disconnect it tune the other , figure out how u want carbs to come on , both primarys same time or just one ect but the carbs will be close , his timing seemed ok til the manifold change , so its plain jane tuning , a wire brush can of brake clean pick a plug run it on primary mile or so shut it off check plug run it wot check plug tuning takes time an is the fun part to see what you created an how well you can get it to run ur timing mark on plug should be right on the bend of electroid , big cams soot up ignoor that , the timing plug mark is a heat in the metal thing a wire brush an brake clean won't remove it so sooty plugs realy dont mean much at all if ur old like to listen to idle lmao
i feel bad saying to change carbs that's probably not what somebody want to hear and the easy way out an won't learn a thing, his mechanical carbs can be tuned just fine , any multi carbed engine no matter if its a train ,plane, motorcycle or car is the same , you pick a carb tune it an tune the others to it, flatslides or su's anything it's all the same , isolate a carb get timing so it runs on idle circuit, run it check plug for midrange then again for wot then set all the others the same, if your running primary's on one an proggresive for secondarys on that carb an all the other carbs opening full bang it will only be a linkage adjustment issue the afr won't change , same goes for running primary's same time then secondary's up to you, so isolate the carbs get afr right an go to town they just have to idle the same an open the same an that's about it for multi carbs add as many as rocks ur boat i did
i did that's why i posted again seems he has it worked out an has big cam so no vac can i wondered bout that , todays post explains multicarbs if you think i am wrong show me how i would enjoy any feedback you have, everyone is trying to help with what they know, until his last post we didn't know he had a lot of duration so vac. gauge is useless there we still don't know if his carbs are running on the idle circuit or if he has idle screw turned in so much they are running off the throttle plates , it's all a best guess try to give best advice thing , we know he is running about 36/38 advance total thats fine an 20 ish int. an if it starts an not breaking starters thats fine to , if i was there with my tools would go through the whole nine yards check all the plugs see where is it at ,vac gauge ,timing light ect ect but non of us are we just mouth pieces trying to help
