Ok got my intake and carb on might need a little help i have read about the mikuni and stuff. Well i am having problems getting it started. Got good spark and fuel at about 4-4 1/2 psi motor has less than 25 miles on a rebuild. Used a holley 600cfm for a awhile but was way to big. Any way now the started aint turning over? What could I have f ed up now? No leaks found so that is good checking all the fuses gonna jack the car up and check the starter. Any other ideas?

Info about the car its a 12A stock port just got back from being rebuilt 5speed.

 

swounds like you need a starter

 

yea taking it off now you dont happen to have 1 around there do you? Late 82-85 12A or 13B. At least thats what it looks like from my reading. O and it has to be from a manual of course. When i get it off i am taking it to autozone to have it tested.

 

also batt might have died from all the cranking. or a fried starter.

for initial startup on this type of carb i like to make sure the plugs are clean and dry, sometimes helps to be sure the engine isnt flooded and turn it over a few times with the plugs out.

put the plugs in and pump the gas all the way down 3 to 4 times, then while cranking give it around 1/4 of throttle and nurse it up as it starts to catch itself.

 

Ok complety off the subject but you gotta see this.

Man would i love to try to build a 10A just for the fun of it.

 

Yea the battery is new and i have another new battery both for fb rx-7's and it does the some thing either way taking the starter off tonight and maybe getting it to autozone to test it to.

 

Ok starter and batt. both tested good. Will be puting them back in tomorrow after it warms up. its gonna get close to 32 tonight. Any other things i can check for? Could it be the ignition switch? I really need help!!!!!!!!!!!!!

 

many things, check that the engine is grounded, check the signal wire

 

I am sure it is grouned good I uped teh stock to 4ga audio ground cable but I will double check it. What is the signal wire?

 

signal wire is the little wire that plugs into the starter. Sometimes it falls off causing a no start situation.

 

Ok thanks I will make sure it is hooked up when i put it back on. Anything elese to look for?

 

Clean all of your battery cable connections and make sure you have a ground wire going from the firewall to the engine block.

 

All that stuff is new replaced it when i had the engine rebuilt. I am thinking about adding a few extra grounds. Everything was working ok with the holley.

 

When we installed jonjonwells Mikuni, it flooded the engine at first and we had a hard time getting it to fire up after that. Even with deflooding and sandblasting/cleaning the plugs, we still had trouble. We finally got it started by jon cranking it over while I used an oil can to quirt oil in the carb. The pic he posted in your other thread was from the first time we got it to stay running on it's own.

 

ok i got 1 of those cans out in the shop some where. LOL I think i might go buy a new 1 at walmart tomorrow before i got pick my father up at the airport. The plugs are new but i am gonna get another set. The air filter housing i got with mine wont fit so i guess i ll have to worry about that after i get it running.

 

Get an oil can that has the pump lever and flexible spout. A small one and fill it with regular motor oil.

 

ok will do I might get it tonight I am thinking about going to Ceasers.

 

Sorry to hear you are still having troubles. Definately try the oil. I would also mention the my car only likes to start with the pedal pushed about 1/4 of the way down. Just a little bit of a sweet spot. I think it needs more air for startup, who knows. Just though I would mention it..... Good Luck, keep us posted

 

Ok went and gambled away $69 in 3hrs. O well i hope i can getup and work on the car tomorrow. I ll keep you posted and should have a camera early next week.

 

If everything looks normal (warning lights on the dash, head lights, etc...) and you get nothing when you turn the key to the start position, it's probably the sensor wire. It's the small clip on wire that goes on the top of the solenoid. Make sure it's a good, tight fit.

If you have trouble starting it while it's turning, a few small sprays of wd40, right down the throat will work wonders.

 

Ok its cold and windy but working on it in steps. Bought an oil can from autozone the young guy at teh counter had no clue what i was asking for. LOL Lucky enough 1 of the older people was able to show me where they was and said the have had that 1 oil can in for over 2 years. O well it works so back outside to freeze.

 

Good luck on getting it to run this time.

 

Almost got it running does any1 have a better pic of the top of the cab need to know which screws i need to turn to adjust. I pumped teh gas pedal 10 times and run for about 2 sec. when i go to give it alittle gas like John said it seams to be flooding out gonna swap newer plugs and try to adjust the carb alittle see if that may help.

 

Ok really close to starting with new plugs but then it did the samething it did last night. Starter not turning over? All the wires are hooked up and everything. What else and why does it not do it all the time?

 

Ok I Need Input Come On Really Stuck And So ******* Close To Starting But For Some Reason The Starter Just Wants To Stop Working. Checked The Ignation Switch And Its Good. Starter Tested Good And So Did The Battery. Replaced The Ground Wire.
