71 mav kinda sluggish

hi i got a 71 mav 200ci...when i press on the gas al the way down it sounds like it wants to turn off and stalls...could anybody help me

 

Sounds like it's time to rebuild/replace the carb. Accelerator pump is probably weak.

 

the carb is new do i need to tune it.? whats an accelerator pump.?

 

anybody knows whats wrong wit my car.?

 

Yes it sounds like it needs tuned. Plus it could be the points in distributor. Might want to check the gap, and see if they are bad. Or the timing might be off!

 

start with trying to adjust the new carb, then check timing , also check the vacuum advance ( both the accelerator pump in carb and vacuum advance will cause it to do what your saying if they are not working right) if you have to change the timing you will have to re adjust carb afterwards.

 

I had a 250 mav. and I know when the points went bad it would want to die. Happened all the time. I had a crappy distributor on it. That is what I would look at first. Then tune carb if needed, then timing.

 

you say the carb is new , so that must be the last thing you messed with bfore you had this problem so thats why i say adjust carb first ( especialy if its a re-man not n.o.s.), and my 71 has a 250 with a poor distributor in it as well its the dual port vacuum advance style point dist. that has been de graded by the last owner to a pertronix electronic ignition instead of points, and it misses at idle and fouls plugs, (the car also has a re-man carb on it in 04,) runs some what ok after idle including when you floor it , no stumble or bog, but seams to surge at light cruise and gets into spark knock at w.o.t. I can't wait to get rid of the dist. and go through the re-man carb fully. the timing is set to spec. 6 degrees btdc etc. etc. im changing it to the 1977 dura spark ford electronic system if found in a comet and go through the carb completely not just adjusting to factory settings, it may have some junk in it as the car has sit quite a bit before i got it . realy not wanting to mess with it ,but the V-8 is not done yet and i still drive it about 500 miles a year. enough about my junk, i say adjust timing first then adjust carb , if you advance the timing it acts like it leans the carb and if your retard the timing it acts like it richens the carb a small amount (notice the change in the idle rpm as well when you advance the timing?) thats why i said adjust carb after timing,but in your case sounds like the carb was the last thing you worked on so I said go back there first, and i do think it is a dist. problem not carb, if it runs and starts ok ,idles, etc. accept for the stumble when you hit the gas i doubt if its points, etc. but anythings possible , ( i say vacuum advance or accelerator pump) but we wont know till the problems found and fixed, i had a car that ran great untill you floored it and then it would fall on its face sputter and die, but would start right back up and run great in any thing but when you floored it, turned out to be a wire that went to ignition had been near a header and was bare in one spot and when you floored it the engine/wire/body/moved enough to ground it out and kill the car, after it came to rest (stalled the engine) it no longer touched and would start up and run fine,till the next time you romped on it.......good luck.

 

where is the vacuum advance n the accelerator pump located at and once i find them what do i do.? what kind of dist should i buy.?

 

Anthony,
Get the Chiltons repair and tune-up guide for Maverick and Comet.
Then get a book on carburetors to see how they work and maybe a book on Ford engines. You have a lot to learn and it is going to take you a while to learn it. It would help big time if you had a friend with some knowledge about cars to help when you start doing things.

 

defintly get the books and a friend who knows cars. why was the carb replaced in the first place?
did it have this problem before you replaced the carb?

 

what Paul said...X2

 

yep i agree get some books , they are well worth the investment, i was lucky enough to have a friend find some ford service manuals from 71 all model lines including wiring schematics and all the other books covering body,chasis,engines, etc. they are very useful even for experienced mechanics as the specs. and detail assemblies can get specific for each car, and having a friend that is more experienced will help you greatly as you move along... don't give up, as none of us know it all, you should see the learning curve I have had with my 08 6.7L cummins... it just takes time. you already are on the right track as this is the best place to come for maverick / comet info and every one here has been willing to help each other if they can, and thats why i think the people here are the best, they have helped me with questions about my car as well , and that makes having one even more fun, best of luck and keep us informed on what you find.!!!

 

Sounds to me like a weak fuel pump or clogged fuel filter.

If it idles and runs fine, but gets slower after mid-throttle, I would be checking that.

 

<p>UPDATE: Well i decided to check the spark plugs and all of them but one had oil residue on them...</p>
<p>after i got new spark plugs the car ran way better..and one of the cables from the dist cap isnt really passing that much power so imma change the points 2morrow..the cables and the dist cap are new..any advice why the spark plugs were full of oil around the tip?</p>
