Farmer Joe Posted January 16, 2015 Author Report Share Posted January 16, 2015 that is just water turned to ice.. the carb doesnt have a heat plate or any coolant passage, so it freezes up pretty well when its cold and wet. 1 Quote Link to comment
]2eDeYe Posted January 16, 2015 Report Share Posted January 16, 2015 Maybe it needs a blanky? 5 Quote Link to comment
wayno Posted January 16, 2015 Report Share Posted January 16, 2015 That's not a good thing considering where you live, it gets really cold there in the winter. How is that issue normally taken care of in the stock situation? 1 Quote Link to comment
Farmer Joe Posted January 16, 2015 Author Report Share Posted January 16, 2015 Maybe it needs a blanky? hahahahahahaha That's not a good thing considering where you live, it gets really cold there in the winter. How is that issue normally taken care of in the stock situation? well, a KA never came with a carb, so its gonna have to be a home made solution. the L or even Z engines had the intake with coolant ports that heated them. the KA intake was never intended to have the carb, and so we reach my dilemma. ive wanted to do an aluminum plate with channels through it that the carb could sit on. it would use the line for the heater to warm the carb up. something to this effect.. its just when its soggy out. the majority of the time here its just the dry cold, so it doesnt happen. 3 Quote Link to comment
]2eDeYe Posted January 16, 2015 Report Share Posted January 16, 2015 That would be an easy piece to make and would probably make a huge difference. 1 Quote Link to comment
Farmer Joe Posted January 16, 2015 Author Report Share Posted January 16, 2015 yeah.. it would help a bunch. add it to the list.... lol i kinda need to just rebuild the whole adapter system. the plate i made works, but it was intended to have the 3236 on it. so the carb is offset to the primary side. the 38 still works, but its offset now too. i want to built something like this.. it would bolt to the KA intake, and the weber would bolt to it. if i could incorporate some tubing into that on the outside face that freezes, it should be good.. we'll see... 2 Quote Link to comment
]2eDeYe Posted January 16, 2015 Report Share Posted January 16, 2015 I might could CAD something up for you if you can get me some measurements. Maybe Datrod or Mklotz could machine it for some $? 1 Quote Link to comment
Farmer Joe Posted January 17, 2015 Author Report Share Posted January 17, 2015 we shall see.. since it runs still, i have some other things that i need to worry aboot before that. i gotta get this thing to stop slurpin down so much oil... 2 Quote Link to comment
datzenmike Posted January 17, 2015 Report Share Posted January 17, 2015 I have a KA exhaust manifold and it has a heat shield on it. Wouldn't take much to connect a stove pipe from it to the carb. You would need a stock style air filter for it to connect to, but the carb would be running on warmed air in about 2 min of running. Good bye carb icing. 1 Quote Link to comment
heretic Posted January 17, 2015 Report Share Posted January 17, 2015 great idea Farmer Joe. kinda like those cast weber adapters. Mike- the KA intake & exhaust are on opposite sides of the head. 1 Quote Link to comment
Charlie69 Posted January 17, 2015 Report Share Posted January 17, 2015 Move to Phoenix that will eliminate any icing problem! LOL Quote Link to comment
Farmer Joe Posted January 20, 2015 Author Report Share Posted January 20, 2015 Move to Phoenix that will eliminate any icing problem! LOL funny you say that... ive had this want to move to yuma... i like the desert.. so i had to tear the weber apart last night... on the way to and from work, even after it was warmed up, it was still coughing right off idle. the idle quality was really suckin bad too.. found that both idle jets were plugged up with junk. the fuel bowl was full of sandy shit too.. blew that shit out, cleaned it up, and slapped it back on. shit runs soo much better now. its been like this for some time, and just got really bad yesterday. drove it to work today. worked great. guess ill check that shit out more often from now on. 1 Quote Link to comment
Farmer Joe Posted January 23, 2015 Author Report Share Posted January 23, 2015 alrighty then.. so im ordering rings and gaskets today after work.. im not selling the truck, in case anyone was still wondering. the carb keeps getting filled up with junk from the fuel system. it needs new filters and i gotta blow the carb out again. hopin that will solve my issues. also bought some parts for the 411.. youll see in june.. 4 Quote Link to comment
]2eDeYe Posted January 24, 2015 Report Share Posted January 24, 2015 Flush that tank and blow those lines clear! 1 Quote Link to comment
Charlie69 Posted January 25, 2015 Report Share Posted January 25, 2015 Yuma not a bad place to live, as long as you can find work. Come on down! 1 Quote Link to comment
Farmer Joe Posted January 31, 2015 Author Report Share Posted January 31, 2015 back from the dead... got the fuel system all figured out. as suspected, the filters were old. not falling apart, but not good anymore. cleaned and blew out the weber again... totally tore it down this time. reset the idle mixtures again, and its working pretty well now. i also got a timing light on it for the first time.. was at 10 degrees, so i bumped it up to 15.. oh and i pulled the plugs for the first time too.. they need replaced, but i cleaned em and regapped em... much better after that.. so now i have these... exhaust cams from a 93-95 altima. 248 duration units. ive since had this done... since theyre from an altima, they have the tangs for the distributor. so we cut em off, and finished off the surface. gonna toss these in tomorrow after work. i have a diagram on how they are installed on a newer KA, so we'll see how that goes... lol also have all this shit.. GMC stuffs... belts, hoses, tie rods, wheel hub assembly.... need more time to get that done.. and then some datsuns... more to come... 6 Quote Link to comment
heretic Posted January 31, 2015 Report Share Posted January 31, 2015 is dude on the forum? I'd love to see more of that truck.!! 2 Quote Link to comment
Farmer Joe Posted January 31, 2015 Author Report Share Posted January 31, 2015 yeah, hes on here but its been almost a year since hes updated his build thread. 2 Quote Link to comment
Farmer Joe Posted February 1, 2015 Author Report Share Posted February 1, 2015 have the cam swap done now.. picture of the cams installed at TDC. live action!! 4 Quote Link to comment
Lockleaf Posted February 2, 2015 Report Share Posted February 2, 2015 Wait, I feel like I'm missing something. Are you running 2 altima exhaust cams, one as your intake cam? 2 Quote Link to comment
Lockleaf Posted February 2, 2015 Report Share Posted February 2, 2015 I just did a bunch of reading on those cam swaps. Very cool. I have a KAE 240sx, so I missed the boat on the cool factory can swaps for the DE. Awesome work man. 1 Quote Link to comment
Farmer Joe Posted February 2, 2015 Author Report Share Posted February 2, 2015 yeah, its 2 exhaust cams from a 93-95 altima. they have the 240/248 combo like a 91 s13 DE. the exhaust cam is the same duration, but the valve event happens at 60* instead of 64*. i think... might be the other way around.. i forget.. i was expecting it to be more lumpy on the idle, but it sounds stock pretty much. i might have to mess with degreeing the cam back a half a tooth to see how it runs. gonna get another cam gear and drill a new dowel hole in it to roll the cam back just a touch. more to come... 1 Quote Link to comment
Lockleaf Posted February 2, 2015 Report Share Posted February 2, 2015 I did see people mention that prefect timing intake side using exhaust cam would need adjustable gears. I want to see that home grown adjusted camgear 1 Quote Link to comment
Farmer Joe Posted February 2, 2015 Author Report Share Posted February 2, 2015 i dont think itll be anything too special.. the cam only has to move a half a chain tooth. i have it set back 3 teeth, and they mention it only needs to be 2.5 back. so ill just drill a new dowel hole on the clockwise side of the current dowel notch. i need to look at a cam gear to see how much a half tooth ends up being closer to the center of the sprocket. 1 Quote Link to comment
