I am in the process of rebuilding my 1978 235 Johnson. I just want to know from you guys that have done alot of these what are the most common pitfalls the novice engine builder experiences with two strokes? I have alot of experience with auto engines as I have rebuilt many of those. Two strokes are a total different animal. <br /><br />My secon question is In the auto world we can get gasket kits for a total rebuild But I dont see a powerhead gasket kit Do I have to get each gasket and seal seperately or are kits available and where<br /><br />Thanks For the replies in advance
