I started anothe rpost as my one from September 2002 was becoming to large.<br /><br />Thanks to 2K Boat, Dhadley and others there is now light at the end of the tunnel.<br /><br />The problem started after a rebuild. The engine ran like a dog and the mechanics swapped just about everything.<br /><br />Things improved when I checked my jets and I thought they were incorrectly located. I swapped them around so the idle was the (14) smallest and things impoved considerably.I had idle 30 and intermediate 14.<br /><br />It is still not running smooth. Idle constantly custs out and when going to WOT the engine gurgles and accelerates slowly.<br /><br />Following advice, I can confirm that the carbs are stamped 431833.<br /><br />I should have idle 45, intermediate 32 and high speed 59D.<br /><br />One problem I know have, where can I get hold of these jets mail order to Oman. Postage can't be much and I wouldn't expect the jets to be expensive either.<br /><br />Thanks<br /><br />NG<br /><br />I have a 1987 140, engine no. 140tlcua
