cad engine slaw allready has gasket attached with a special sealant to the head so it just needs to be sat on bottom and works fine.
but your right about the copper gasket on the other engine but i hadnt any around,i may order some up and throw them in
along with pico unit like you suggest,im waiting to get a few pound from a fella i built a wall for and for some strange reason he is avoiding me like the plague
after spending 2weeks in -5 conditions now he cant pay me lol
oh well im used of it in the building trade
i am getting engine helicoiled tomorrow slaw,and i cant wait to find whats causing the problem then,i will order a new tank and lines before i proceed.....
i am going to take a chance with carb but if problem persists new carbie here also
