CSS

going to change spark plug, trying to find gap setting also i know they have to be indexed towards fuel injectors but how close should you get them as far as indexing.another question, this motor seems to start hard when cold , it takes several trys before it will start, it pops when it turns over than you have to try again and again several times and when it does start it runs a little rough for just abit then clears out then runs fine. fuel filters changed, brand new fuel pump assembly. realisticaly how many atempts should it take to start this engine. another observation ive noticed is it seems to start harder when in water as compared to when on muffs in driveway. thanks for any input css
