Dhadley was right on the primer pump problem. The new gaskets did not have a hole. I removed them and drilled a small hole in the gaskets and things work fine now on start! Thanks.<br /><br />Should I go to the tach problem next, the water pressure gauge, or the "synch and link problem"? Description of problems reposted below:<br /><br />1) The idle was a little too fast for the trolling I do so I attempted to slow it down a bit. I adjusted what I thought was the idle and it did slow down the motor however, I lost top end speed by what feels like 1000rpm and 10 knots per hour.<br /><br />2) The tach (Original OMC) did not work correctly (before and after my work on the carbs), it showed about 1000rpm at idle and dropped to zero on acceleration. Occasionally it would jump up to 3000 and then drop back down. I replaced the tach and the new one (OMC also) works better- seemingly correct until 2800 rpms and then it drops back off.<br /><br />a) Old tach and new tach were/are wired in the following way. Five wires come out of the loom.<br /><br />2 Purple wires- One to 12v ignition, one to the post marked 12v on the OMC tach.<br /><br />1 Gray wire- Goes to the post on the tach marked pul.<br /><br />2 Black wires 1 goes to the ground post on the tach the other is/was not connected to anything. Where does this one go? When I check it with my ohmmeter, it shows that it seems to go to ground.<br /><br />Earlier posts on this tach problem suggest I may have a bad regulator- however, I'm reluctant to replace the regulator without a good manual and until I determine whether that extra black wire is important.<br /><br />I do have a water pressure gauge but I have not yet installed it. Is there a port or outlet for the nipple on my engine or do I have to drill and tap?<br /><br />I know, it's a bunch of problems...<br /><br />Dave <br /><br />Dhadley wrote: (A good project, I love it!<br /><br />OK, lets start with the starting. First of all make sure the primer is working. Pump the bulb up tight and pull a primer line. Have someone engage the primer with the key. It should squirt fuel. If it does, then we may have the wrong base gaskets on the carbs. The correct ones have a hole that lines up with the primer nipple. No hole, no prime. What brand kits did you use?<br /><br />Lets look at that first and then go thru the rest. I think youre right about everything else. The correct sync & link will get the rpm's back. And the regulator is most likely trying to bite the dust on you.<br /><br />Let us know about the primer.)
