the engines came with manfolds, but the age of the manifolds in unknown.(engines are not brand new, just new to us) they are closed cooled, so that helped. We are going to pull the manfold today and hook a hose up to it and cap the other end. this should tell us where the problem is...
one engine runs perfectly, the other plain old sucks... go figure. LOL the joys of twins...
the engine having the problem, is the one we showed in al the running vids earlier in this thread.. the one running perfectly, shown in the last vid, is the one we were waiting for parts for and never got a vid of on the ground...
Problem is, the manifolds got all mismatched, and i cant say for sure if this particular manifold was ever run on either of the engines in the past.. We swapped alot of parts around to save time and avoid too much dismantling and rebuilding...
engine that has the problem, way back when, running perfect
