dolphin Posted November 4, 2017 Report Share Posted November 4, 2017 I don't know if any of you remember, but I bought a dolphin camper, 1978 and just finished a weber conversion, I also have a hitachi carb and air cleaner for sale or trade, or...? I'm trying to figure out how to hook up an automatic choke, and is it even necessary? how hard is a cold start in this, and which wire do I hook up? there are about a zillion different hoses and such, to try and hook up, not even sure where and/or how? I hooked up the line off the valve cover with a hose to the smog gizmo on the engine, that is run by a belt, but I'm thinking of cutting that belt and getting rid of that, if it helps the air, then I'll leave it on, I'm registered as a vintage vehicle, so I can skip that, but salt lake city is the seventh smoggiest city in the USA, so....I don't want to contribute to that. I plugged another pipe with a bolt. I'll try to post a video on ebay, and let you folks know about the conversion, sorry, I should have done before and after. Same title thanks to all more to come lewisg (at) xmission dot. com Quote Link to comment
datzenmike Posted November 4, 2017 Report Share Posted November 4, 2017 I would cut the bottom off the stock air filter and make an adapter to fit the weber. This will let you get to keep the ATC (air temp control) and the warmed air from the exhaust manifold. Essential for preventing carburetor icing below 35F. There are two wires to the back of the stock carb. The Blue wire is the power for the electric choke. Connect this to the weber'sa electric choke. 1 Quote Link to comment
datsunaholic Posted November 4, 2017 Report Share Posted November 4, 2017 You hooked the valve cover breather to the air pump? That'll make it smoke if it was the inlet to the air pump! It'll pull oil right out of the engine and pump in straight into the exhaust! The valve cover breather is supposed to go to the air cleaner. Weber kits don't come with a hose for that, so you'd have to come up with something. Or run a filter on the valve cover elbow- it's an INLET. Or at least it's supposed to be. There shouldn't have been anything to move with the air pump, except the anti-backfire valve's connection to the air cleaner. If you don't hook up the automatic choke, it'll be "ON" all the time, resulting in a way rich condition. You just use the original choke wire. 1 Quote Link to comment
difrangia Posted November 5, 2017 Report Share Posted November 5, 2017 'Redline' makes this adapter that allows using stock 620 air cleaner on the 32/36 carby. get it from Redline, Pierce Manifolds, Ebay, or wherever fine Weber products are sold. I've a carb and this adapter, as I want the stock cleaner, but haven't installed on the 78 'Longbed' yet. i have a jetted-down 32/36 Weber on the 1200cc in the 320 and love it. Here's the adapter: Quote Link to comment
difrangia Posted November 5, 2017 Report Share Posted November 5, 2017 For best results, use only the 'Real' Spanish manufactured Weber. It'll have 'Made in Spain' cast into the carb body casting. I've also been led to beileve that the real Webers with elec. choke will have a white choke heater element housing. The knock-off carbs will have a black housing ?? Quote Link to comment
datzenmike Posted November 5, 2017 Report Share Posted November 5, 2017 If SLC gets below 35F you really need the stock air filter. Quote Link to comment
datsunaholic Posted November 5, 2017 Report Share Posted November 5, 2017 If SLC gets below 35F you really need the stock air filter. I've never had an issue using the Weber filter. Quote Link to comment
datzenmike Posted November 5, 2017 Report Share Posted November 5, 2017 Carb icing can happen to any carb that sees below 35 and high humidity. Not every time but under certain conditions. I find snow on the ground melting and fog is worst. (I'm at sea level, higher may be worse?) The carb body is super cooled below freezing by the evaporation of gas. Frost forms all over the venturi like the inside of your freezer and it stops working. There is a loss of power and your foot goes further towards the floor until you can't drive. You pull over, but it idles just fine.(different circuit) Warm air under the hood can melt the frost in a few minutes and you drive maybe a half mile and it repeats. Quote Link to comment
distributorguy Posted November 6, 2017 Report Share Posted November 6, 2017 Living in MN, I've never experienced carb icing. Weber floats are always set wrong, and that affects how the vehicle runs more than any other adjustment. All Webers are NOT created equal. As far as I know, Pierce is the only importer selling real Webers these days. Redline is one of the biggest offenders for selling the Chinese knock-offs, despite the castings appearing nearly identical. When you see the overly-shiny zinc plated garbage that Webercarbsdirect or EMPI sells, run like hell!!! Pure awful. Does it work? Maybe, but nowhere near ideal. Quote Link to comment
banzai510(hainz) Posted November 7, 2017 Report Share Posted November 7, 2017 most weber kits will have a adapter which raises the height of the carb so jut to let you know the aircleaner may hit the hood. esp if you add the stock weber top adapter for the stock aircleaner. They still make stock round aircleners??????? Quote Link to comment
haunsolo7 Posted December 20, 2022 Report Share Posted December 20, 2022 Hey man I think I bought your dolphin, based in SLC, registered as a vintage vehicle, bunch of the egr and pvc system plugged/removed. Whoever owned it in between us absolutely destroyed the interior lol, reeks of weed. I'm currently in the process of trying to get it to pass emissions, idk if the laws changed or if maybe you were in a grey area but now the DMV will not let you register an RV as vintage in utah if you plan on using it as an RV, I could have probably just winked, nodded, and pinky promised that it would not ever be used as a camper but oh well, like you said smog here is pretty bad so I don't think the emissions requirements are a bad thing 2 Quote Link to comment
