FStroke 225 HP Rough idle
I have a pair of 2003 FStrokes 225HP. They have 330hrs each and both were running pretty smooth. Last weekend one of them turn on fine but in idle it like missing one spark. It is shaking in idle and when I push the throtle it is worst. After warming up for a while it runs fine, I was able to run at 26mph and it was not shaking. It stays on.
I check the spark plugs and all of them look fine except no. 1 which look way to dry and brown. I check the coil and even swap it with the other engine and had the same issue. Checked the spark, it is ok. I guess, it is not electrical problem.
Check water separator it was ok, checked the canister filter and primer bulb they were ok.
Could someone please suggest what else I shall look for? Your help will be greatly appreciated.
