Hi Guys,
Having a strange issue that's come up recently, where my crossflow needs a lot more than 20 degrees advance to even idle. Any less than that and it just dies. I can't get an exact reading as I don't have an adjustable timing light, and the pulley mark is so far away from the markings on the chain cover. It will drive like this, but feels sluggish.
Even with the advanced timing, combustion still doesn't sound right, and sounds like it might be continuing into the headers.
Any ideas what would cause this? Other than very weak spark, I'm out of idea's.
A bit of backround
I have had the same engine set up for 7 years or so, but recently had a few issues with the car stumbling and dying, and then not restarting for half an hour. After cleaning up the idle mixture and still having the issue, it was pretty clear that it was an ignition problem, as the engine would start but now miss badly (on all cylinders), backfire and be extremely sluggish.
I have cleaned up the earths and connections associated with the electronic ignition and brought a new coil for it. Re-timing the engine after all this, is where I noticed that it needed more timing than usual to run (historically has run happiest on 10 degrees static). It still feels sluggish, and I'm not willing to drive it very far, as I doubt I will make it home again.
Engine specs
1660 xflow
BCF2 cam on vernier pulley - timed the cam in myself and it has run nice for the last 6.5 years, so unless its suddenly moved....
Petronics electronic igniton and correct associated flamethrower coil.
32/32 carb (too small I know, has run fine for years)
Any thoughts on the above would be much appreciated. Unfortunately I doubt I still have the points set up I took out of it many years ago. Trying to avoid throwing a new electronic ignition at for the sake of ruling it out as they are $$$.
