Poorly Running Engine FIXED!
 

I bought an old Carbide 150 dune buggy around a month ago. It was not running at the time so I got a great deal on it. Finally got it running but it ran like CRAP! and would cut off after around 5 minutes. Read alot of postings about similar problems with a ton of different suggestions. The carburator was the most common suggestion, followed by the auto choke. After tearing down the carb twice and putting on a new auto choke, the engine still ran like crap.

Then I read a few postings that suggested a valve adjustment. For those who have never opened up an engine, have no fear. I found a video on youtube under "gy6 valve adjustment" that walked me through it. I spent less than $7 on a set of feeler guages at Auto Zone and it took me less than 20 minutes. Put it back together and the buggy runs like a champ! Set the intake at .003 and the exhaust at .004. Definitely fixed the poorly running engine problem.

Thanks to everyone for the advice.

That's awesome! Glad you got it running right.

yep
 

i did the same thing to my dazon 150's and it fixed the running issues, but now my engines are smoking a bit, does any one have any clues as to why that would suddenly start happening? keepem rollin bear

Bad rings or valve seals comes to mind first.

Have you done a compression test lately?

had them do a compession check at prostock performance n ken said it showed about 50psi but that was before i set the valves right and got the engine running right would that make a difference?
