Proud of myself first major project bought a boat with cracked block and redid it all by myself...just read the book lol<br /><br />Anyway its all back together and in the boat...but it wont idle right and surges on the low end<br /><br />Cant time it proper due to the pulsing from 900-1200 engine temp is great and at 2000 it runs smooth and nice... tho timing is out still<br /><br />Checked all the manifold area and replaced carb gaskets...carb cleaner wont smooth it out much...advice?

sounds like typical vaccuum leak, as well as timing problems...Tune it up! and check the vaccuum, (with a gauge)....sl
