Shagy Posted August 15, 2011 Report Share Posted August 15, 2011 good to hear..... Not a blown head gasket @ all?? Quote Link to comment
r0p0doe Posted August 16, 2011 Author Report Share Posted August 16, 2011 Cylinder 4 has low compression,cars lacking power because carb needs to be tuned still. Found the electrical problem its a wire connected to my alternator that drains the battery Quote Link to comment
Shagy Posted August 16, 2011 Report Share Posted August 16, 2011 If you ever make it up this way we can do a leak down test and check valve seats & rings..... Run some MMO in it. Quote Link to comment
motavated Posted August 16, 2011 Report Share Posted August 16, 2011 Here is the whole story. 1.)The carb is a manual choke weber. The choke is just dangling. It is missing parts on the choke to make it work. That could cause that power problem when you drive if it, the choke woudl just close? 2.) Checked the compression on the l20b. Piston 1,2,3 are at 150psi while #4 is at 90 psi.. I wanted the adjust the valves but the valve cover was silicone on. But that #4 is really low. Don't know if adjusting just #4 is going to bring it back up. 3.) The carb was over jetted. When I removed the plugs, they were dark and oily. That was causing the car to misfire. Lucky I had some plugs in my car and I swapped them out. You know it was bad when you turned the motor over. Gas would shoot out of the spark plug hole. After changing the plugs and adjusted the carb and let the extra fuel burn off. It was idling like a regular l20b with a low compression piston is supposed too. 4.) there was a lot of oil coming from the side of the block. Could be a bad gasket. But the block has to be cleaned and driven to check for leaks. Or a leak down test. But I don't have the tools for that... :( I think the reason the car had more power before was that is was over jetted. Also maybe the timing is off. But I was told that it was adjusted all ready. With the car not having plates. Its very hard to get the car to run 100%. Adjusting the carb and checking for leaks, well you just have to drive the car and keep adjusting. But from not being able to idle to sorta drive it around the block. That was a big improvement. If someone wants to go at it again. let me know. but that is what I got from it pretty much...

motavated Posted August 16, 2011 Report Share Posted August 16, 2011 No plates???? You cant drive it on the street. Not registered with the DMV = no plates. You can drive it around the block. But that is pretty much it unless you want your car towed away. Quote Link to comment
r0p0doe Posted August 16, 2011 Author Report Share Posted August 16, 2011 Yea no registration at the moment because it's not really in daily driveable condition.but motovated is spot on with everything, a lot more needs to b done Quote Link to comment
Shagy Posted August 16, 2011 Report Share Posted August 16, 2011 well that sucks. I have a leak down tester. Might be time to buy new jets. Pour some MMO in Cylinder 4 and let it sit for a couple days. Maybe you'll get lucky and it will be some crap in the rings and it will free it up. Quote Link to comment

72dyme Posted August 17, 2011 Report Share Posted August 17, 2011 So all u need is a better carb, valve cover gaskets, spark plugs, and a valve job? That stuff to change out should be less then half a days work. I'll see if i have anything u can use. Don't sell it cause of that, I'll let u know what I find. Quote Link to comment
danfiveten Posted August 17, 2011 Report Share Posted August 17, 2011 My wife knows if she told me to get rid of my 510, id tell her she could walk out the fucking door because it was here first, if she cant respect me, and the things that make me happy, then i dont want her in my life. 1 Quote Link to comment
Shagy Posted August 17, 2011 Report Share Posted August 17, 2011 Rory, 3207 Peck Road El Monte, CA 91731-3429 (626) 350-8245 call them. they can rebuild the carb. IF your jets are wrong, you need to figure out which ones you need and buy them. I called the guy and they will drop in the new jets when rebuilding it. I've never changed out jets (it might be a cake walk). The VC gasket and spark plugs are easy. Also the Valve adjustment. Quote Link to comment

Drove it once and blew it up... Ouch, someone must not be too happy with me. Im still looking around trying to find what I need, I looked on weber for the missing choke linkage but there was nothing there. Probably try and sort out some problems again this weekend Quote Link to comment
Shagy Posted August 17, 2011 Report Share Posted August 17, 2011 That carb rebuild shop should be able to take care of all that stuff. Quote Link to comment
