Carbide won't run with air filter attached.....WTH!
I took my lightly modded carbide out for a spin and it won't get over 5mph. Once it gets to 5mph it just Boggs right down almost to a stall, it tries to rev back up but it just keeps going back down to a stall, but never stalls.
It was running fine a few days ago. I took the carb out and thoroughly cleaned it, carbs don't get cleaner than mine at this point, I was very thorough. Decided to check if my battery was getting charged. While at idle i. Only getting 13v max. I swapped the rectifier from my other carbide, no fix at all. Swapped CDI, no fix at all. Swapped the coil, no fix. Plug looks fine too. I took the air box off the carb to so that I could rev it up and watch the gas spray in the carb. When I did this no bogging down at all, what? When I put the air tube back on without filter it went right back to bogging, take it off no bogging again....WTH? Swapped the velocity stack and uni from my other carbide, still bogged when revved, take it off no bogging when revved.....WTH? I'm so lost, I don't know if I have a charging/ignition problem that it causing the bogging or what. Stator maybe? What else is there? Forgot to mention that when this all started the tach went crazy too. At idle it it would jump around from 50mph to 106mph. Also the miles started jumping around, it now says I have 0 miles on it.

Start checking ground connections.

I took the carb out again and dropped the pilot and main down a few sizes.
I also noticed that one of the choke screws was a bit lose, choke seemed to be in there securely though. Which ever one of those i did fixed the problem. Dont know for sure since its raining but when in neutral i can rev it out and it dont bogg down no more. Couldnt do that before.

Picky,picky!
I can relate to this! I went thru kinda the same thing on my red dazon, I just kept taking the carb apart thinking I had missed something. I come to find out my intake tube was worn out and collapsing just enough to affect flow, causing the carb to act up!

I just wish I could put some miles on my carbides without issues. It's getting ridiculous.

If you have the stock air box, I have seen these buggies blow/suck oil into the air box from the breather on the valve cover. It clogs the air filter up and wont pick up rpm's.
Oops. Just re-read. Not stock box. Last edited by 351mustanger; 04-14-2014 at 05:27 PM. |
