d.p Posted June 16, 2021 Author Report Share Posted June 16, 2021 I grew up in CA (Bay Area) and went to college in SF. Just never seen another 521 on the road and have seen 3 total including mine in person ever. 2 Quote Link to comment
banzai510(hainz) Posted June 16, 2021 Report Share Posted June 16, 2021 (edited) pretty common here in Washington on craigslist in pieces in back of people yards or apartment complexes with garbage in the bed Edited June 16, 2021 by banzai510(hainz) 2 Quote Link to comment
d.p Posted July 18, 2021 Author Report Share Posted July 18, 2021 If anyone’s wondering (which they most likely aren’t) I get roughly 21-23MPG on a built L20b, dual mikunis, a 5 speed and a heavy right foot running 93. 1 Quote Link to comment
datzenmike Posted July 18, 2021 Report Share Posted July 18, 2021 I think my stock L20B 620 got 28MPG if on a highway trip. This is with an imperial gallon so converted to US gal that's 23.3. That's GOOD!!! What do you get if you're trying? 1 Quote Link to comment

If I drive easy I imagine a couple more miles per gallon. It’s a fucking blast on the freeway whereas with the anemic l16 + 4speed fucking sucked there and everywhere else. I wonder what a KA would feel like? 1 Quote Link to comment
d.p Posted July 18, 2021 Author Report Share Posted July 18, 2021 Does anyone know what the tank size is for a 521? I try my hardest to run it down to completely empty but have yet to run out of gas. 1 Quote Link to comment

d.p Posted July 19, 2021 Author Report Share Posted July 19, 2021 Well shit I never even get close to empty then. Closest I’ve gotten is 9.4 and still have a gallon and a half to go. 1 Quote Link to comment
thisismatt Posted July 19, 2021 Report Share Posted July 19, 2021 I ran mine out of gas in the middle of town during rush hour on a street with no shoulders 🤦♂️ 1 Quote Link to comment

I always picture myself like Kramer and George in Seinfeld when they test drive that Saab and run it to empty. 1 Quote Link to comment

d.p Posted July 19, 2021 Author Report Share Posted July 19, 2021 You’re right. I guess it was the salesman and he ducked out before they ran out because he couldn’t take it? My memory is fuzzy but I loved that one. 1 Quote Link to comment
thisismatt Posted July 19, 2021 Report Share Posted July 19, 2021 I tried to post a gif of it earlier but it was too big 😅 1 Quote Link to comment
d.p Posted July 20, 2021 Author Report Share Posted July 20, 2021 Truck died this morning….started miss firing then now it will barely idle but when I give it any gas it dies. All heat are tight and where they are supposed to be, I can squirt gas in the carbs manually, there spark at the coil wire and the plugs look good. The only thing I noticed is I have calcium deposits in my plug wires on the dizzy side where they plug into the cap. 1 Quote Link to comment
d.p Posted July 20, 2021 Author Report Share Posted July 20, 2021 Replaced plug wires no difference. Seems fuel related so I went ahead and changed the fuel filter but it’s not filling with gas at all even when I try to crank it over. So pump or fuel line related? How can I test the pump without taking it off? Called for a tow back to my house as well. 1 Quote Link to comment

I never change plug wires. Only maybe for looks. NGK wires dont go bad all too often I bet a jet block got loose inside the carb. Mine go loose for some reason. it will cut out but idle. I would check that first Fuel? I stock pump usually never goes bad unoless made in Chinese clone but EZ to check. if elelctric pull the line off and shoot the line in a safe direction, Simple. 1 Quote Link to comment
d.p Posted July 20, 2021 Author Report Share Posted July 20, 2021 Well cracked this case. POS airtex pump shit the bed. Have another going to throw it on but the spring is down in the timing cover, do I need to worry about that? will order a better pump as wel. 1 Quote Link to comment
d.p Posted July 20, 2021 Author Report Share Posted July 20, 2021 Well that seems to have fixed the fuel delivery problem but now my battery is dead from trying to crank it over. Guess I just wait for the tow truck and have them tow me home or give me a jump. and @banzai510(hainz) I’m not using NGK wires…was using MSD and like to try the simple things first. And why would I have calcium deposits on the dizzy cap side inside the wires? 1 Quote Link to comment
thisismatt Posted July 20, 2021 Report Share Posted July 20, 2021 Maybe you can fish out the spring with a magnet? 2 Quote Link to comment
Crashtd420 Posted July 20, 2021 Report Share Posted July 20, 2021 Just push start it.... it's a standard... Get it rolling, put in gear, pop clutch... I usually like 2nd..... 2 Quote Link to comment

banzai510(hainz) Posted July 20, 2021 Report Share Posted July 20, 2021 condensation under the cap maybe cause of humidity Try to find a better fuel pump if possible. I got one Japan made one left but also have the chines clones as spares. as for the spring going down. I would not worry about it too much it woont get sucked up but I guess could bounce around in there. but maybe get a magnet plug and it will work its way to that and you can pull it out 1 Quote Link to comment

Never make it in the 3rd world!!!!!!!!!!! 510 and 521 mostly use a KOYOSAN BRAND AND LATER USED nIKKI BUT ITS MOSLTY THE INPUT OUTPUT LOCATION IS DIFFERENT as the 620 hose came from different locations turn Key to ON before pushing the vehicle to roll start it Edited July 20, 2021 by banzai510(hainz) 1 Quote Link to comment
