July 19, 201213 yr can you put a ea81 carb on a ea71? i have an 80 ea71 and i have some good ea81 carbs sitting on a shelf, could i use one of those for a while untill i can rebuild my original carb? if so what kind of problems am i going to run into? i know some of you will say to replace with a weber but i don't have the money to do that, i just spent close to $400 on my suspension.
July 19, 201213 yr have u tried putting on the carb. yet? when u do u will realize the the ea81 and ea71 have different size base/different place to blot on, so u would have to build a adapter plate so your better off waiting to rebuild carb. but the the ea81 will give u more hp than the ea71 carb
July 19, 201213 yr Author i was afraid off that, but i might be able to make an adapter plate. i might just do that instead of rebuild. i just relized that i ordered rebuild kit for wrong carb, so i am going to have to do something different.
July 19, 201213 yr Im not sure that is true, the ones I have done in the past the base for an ea81 and ea71 were the same bolt pattern.
July 19, 201213 yr Author hmm i will have to look into that. i was able to take some of the parts out of my rebuild kit and do a repair on my old carb. but i will look at the carbs i have and see if it is worth while to do a swap. if they bolt right on i might just do that for a cheap horsepower upgrade untill i can get a weber.
July 19, 201213 yr i put the ea82 ohc carb on the 1600 have to hog out the hole a bitt and retap the bolt studs out a bitt but dam that carb works good have it on my 77 wagon way stronger than my 80 stock brat by probly 10-15 hp the ea82 carb has masive secondarys
July 19, 201213 yr Im not sure that is true, the ones I have done in the past the base for an ea81 and ea71 were the same bolt pattern. i tried putting a ea81 carb. on my dads 78 ea71 brat once it was a different bolt pattern so it wouldn't fit without a adapter plate
July 19, 201213 yr Author it probably depends on year of the ea71 engine and the year of the ea81 carb
July 19, 201213 yr it probably depends on year of the ea71 engine and the year of the ea81 carb measure the base of the carbs first before u take it off
July 20, 201213 yr Author i definatly will i just got my shocks in today and got my repaird carb back in and it is working good for now i think i will wait to mess with it till later and i might just do a weber swap. thanks for the help much appreciated
