HELP!!4AGE small port/red top convert to silvertop quad....

[NoHachi]

No explosion in a single chamber is either:
No spark
No fuel
No air
No compression

And the lower you go in the list, the lower the probability becomes.
First make sure you have a spark at the cylinder. Don't assume all is fine, physically check that you have spark and that the gap is set appropriately.

Next check for fuel. Highly unlikely that it won't have any since 4AGE's fire in batchmode. Buy one of those car stethoscopes and listen if you can hear the injector ticking. Maybe improvise with a screwdriver and some common sense. Might be a ground or electrical problem thats causing trouble.

No air..maybe grosly misadjusted throttle plates? Can you feel it sucking air at idle?

Compression..this would be a very weird one if its ok with the stock manifold.

I don't think you can solve this problem by simply throwing an emanage at it..not if a single cylinder is not firing at all. you'll do that later to get back the hp you are losing in this conversion.
