I have a meerkat 50 with ~200hrs that just stopped running while idling
It only runs for a couple of seconds
changed with new: carb,spark plug,gas,cdi,voltage regulator,coil,magneto/pickup assm.,new cylinder, piston,rings,head assm,head gasket
wiring checks out ok
was 35 psi compression
now 50lbs without carb
still only runs a couple of seconds,choke doesn't help,push throttle and kills it immediately
ring gap old and new top and bottom around .012"-.016"
I think ring gap should be .004"x1.53"=.006"
just doesn't seem like it has enough compression but everything is new
timing looks ok, mark on cam aligns when flywheel at mark for TDC
flywheel key ok
any ideas would be appreciated!
Thanks!

 

I am having same issue. Did you ever get your ATV fixed? I cleaned carb, valve adjustment and swapped coils, plugs and cdi. Still dies same as yours.

Thanks,

 

One thing to check, look and see if theres a hairline crack in the inlet manifold swan neck, especially if the carb seems to sit very close to the top chassis tubes. When mine cracked the split was almost impossible to see until I actually unbolted the manifold from the cylinder head. Theres not a lot of clearance between the top of the carb and the frame especially if the frames distorted a little through age & use
