The Ficht is a totally computer controlled engine. You really need the software/ computer to properly diagnose it. But there are a few things we can do to see if we can find the problem.
First we need to do a compression test followed by a spark test. You'll need a spark tester to check spark, available from any auto parts store.
Remove the spark plugs, do not mix up which cylinder the spark plugs came out of.
What do the spark plugs look like? Are they Champion 7712's? Are they carbon fouled?
What tachometer do you have? Do you have a SystemsCheck gauge?
Give me the answers to these auestions and we can go from there.
Sure, just post back and I'll respond as soon as possible.
