sorry to jack the thread, but couldn't you in theory just use one side of the spark plugs?
Ive got a VG so i have no idea about the CA's, but it comes with two separate sets of plugs right? the first set to Ignite the fuel, and a second set to help burn off left over fuel so that it could comply with US emissions standards... this of course is just what i've read...
for example, a Mazda 13b has two sets, a Leading plug and a Trailing plug... the trailing are fired to burn extra fuel, but if you disconnected say the trailing or leading, it would still run off of one plug per rotor..
.
couldn't you just in theory, take one set of plugs loose, and adjust the timing and use only one set of plugs? I mean, not as a permanent fix but as a temp thing so you could at least drive it
please excuse my crazy logic
good luck getting that thing out mang
