Bossdaddy 212 Posted April 5, 2022 A friend brought a Big Red by for me to look at and see If I could help him out. It will run but poorly, leaks fuel not only at overflow hose and seems the throttle cable is sticky and don't work smoothly and respond quick. Where do I find a rebuild kit for the carb and new throttle cable. I will even buy a carb if I could find one. Any suggestions will be appreciated. Share this post Link to post Share on other sites
THH 297 Posted April 5, 2022 Shindy kit from Rocky Mtn ATV Probably will have good luck on Ebay for throttle cable. 2 Share this post Link to post Share on other sites

toodeep 1,760 Posted April 6, 2022 Throttle cable is probably still good, they was made back then (nothing like the 70s but still better than today). The throttle plunger is probably gummed up in the carb since they are still all manual on those. I would start with a good carb cleaning and then go from there. 1 Share this post Link to post Share on other sites
Bossdaddy 212 Posted April 6, 2022 Thanks Fishfiles, toodeep, it will still operate, it's just slow, I think I can get it working right. I do appreciate all the other options I have, thanks guys. 2 Share this post Link to post Share on other sites

Maybe someone messed with the throttle cable adjustment so kids could ride a little more safely or installed the cable improperly Share this post Link to post Share on other sites
Bossdaddy 212 Posted April 6, 2022 I say slow, what I mean is slow to respond. I can push to accelerate, let off and it come back to normal real slow. So naturally engine comes back to idle slowly. Share this post Link to post Share on other sites
TBRider 1,411 Posted April 6, 2022 Might just need to lubricate the cable. 1 Share this post Link to post Share on other sites
Bossdaddy 212 Posted April 7, 2022 I pulled the carburetor off and the throttle cable is fine, free and smooth. The carb. is like sticky in all operations. I've ordered a rebuild kit for it. I believe it will build good and work out good for him. 1 Share this post Link to post Share on other sites
jeepwm69 7,751 Posted April 7, 2022 Boiling in lemon juice works pretty good on carbs, but an overnight soak in Berrymans is better. Share this post Link to post Share on other sites
Bossdaddy 212 Posted April 7, 2022 It started soaking last night. Share this post Link to post Share on other sites

I've ordered a rebuild kit for it. I believe it will build good and work out good for him. That was my guess. If you took the throttle slide out/apart use just a little loctite on the those screws when going back together. In the past I have found a few sitting on top of pistons or holding a valve open. It's not common but can happen. If your not familiar with that style of carb you also need to check the throttle timing (butterfly and throttle plunger open at the same time) when going together. 1 Share this post Link to post Share on other sites
Bossdaddy 212 Posted May 13, 2022 I forgot and never finished this thread, sorry. I rebuilt the carb, it was really dirty, it cleaned up good. It fired up nicely and with very little adjustment it ran like a new one, the guy is happy, and it didn't cost him much. No leaks and plenty of power, brought back a lot of memories. I tried to buy it, like I need it, lol. Thanks again guys 4 Share this post Link to post Share on other sites
