hi guys change me mainfold today put it all back together every wire in right place and fuel lines as i marked them up think sum water went down into the engine he prop ive got is that when u hold it at 2000 ish rev it juggers any ideas cheers

 

Don't hold it at 2000 rpm for starters if you suspect water has got into the engine. If you compress it you will be like this >>>

 

If its been running it should be out now perhaps some hit a plug giving a missfire if its that it should clear

 

it ticking over ok now run temp ok revs ok was just bit spliiter no water in oil etc going take out later so will let you all no thanks for help
