    Twin 40 Webers - Ignition Advance and Remote Servo Vacuum

    Hi Everyone,

    I have a 1660 crossflow, with a 234 cam, high compression pistons larger valves and ports etc for fast road use.

    I need to buy an ignition system for this, so i thought I would look into the accuspark kits. Do I need to buy the kit with the vacuum advance and will this fit fine with my remote servo vacuum line as I only have one vacuum port on the inlet manifold.

    Apologies for the noob question, but this is the first time I have looked at this kind of thing.

    Any help would be much appreciated!

    the vacuum advance wont work properly connected to only one inlet tract, that and the fact the distributor base plate ( and thus timing) is more stable without vacuum is why most things with twin sidedrafts do not use vacuum advance

    Thank you for your advice. I was wondering how it could possibly work if it was only on one inlet. I will buy the non vac kit now then.

    how about a mapped ignition system? i have an omex ecu and loom for sale and its mapped for exactly that engine, the only thing you would need it a trigger wheel and sensor mounting and a tps sensor for the carbs. if you are local i could help you out with the install and aligning the wheel and synchronising the ecu to the engine sensors

    I may do at a later date, but I just want to get my project finished for summer at the minute lol. However, thanks for the offer. I am actually now living in Tibshelf not sheffield, so about 10 miles away.

    Just out of interest, how much is the set up?
