Hensim 70cc atv

Earl · 04-29-2008, 09:53 AM

Hi,

I am new to the club and desperate for help with a Hensim 70cc atv. It has been a good rider for my 8 year old son. However, after sitting up this winter it will not start for some reason. I took the spark plug out and held it against the cylinder head while pushing the ignition. There is spark so I next checked fuel and it seems to be getting fuel by way of a "wet" spark plug. Could it just be that the spark plug itself needs to be replaced?

Also, what the secret to draining the oil in this unit and is 20w-50 recommended?

Thanks in advance. I appreciate the help.

I suggest you shut-off the fuel to the carb then drain the carb float bowl (screw on bottom of carb). Once empty, turn the fuel back on, pump the throttle a few times and try to restart.

Stale fuel in the carb is often the cause of failed starting come spring. The same thing routinely happens to both my Kawasaki and Honda.

It wouldn't hurt to get a fresh plug too.

Out of curiosity, for you winter guys (or others who might long term store a bike) would it be sensible when storing it to remove the gas tank (pour the remaining fuel into your car or something)?

Earl · 04-30-2008, 11:30 PM

Absolutely, I should have drained the fuel!! I definitely learned a lesson. At a minimum perhaps I will use a fuel conditioner before next winter hits.

If you leave the tank full it doesn't leave room for condensation causing rust. Not an issue if the tank is plastic. Drain that gas in the spring and put in fresh.

I used to take the stored gas on burn it the tractor/old truck. It would be diluted down then.

That's a good tip. Thanks again

I sell the hensim brand and others.Often the fuel line/pump gets a vapor lock that is remediedby disconnecting the line before and after filter or vacuum pump if one on unit .Once fuel flows usually problem solved.

i'm a hensim dealer and maybe i can help.

i think the other post done the job for you already.

good luck

Thanks everyone. Got her running this weekend only to find out the gas tank leaks. I have conacted the dealer and they are shipping out a new one. At least it's running. I appreciate the help.

When I stored my bike I added fuel stablizer, 2 oz. I always keep the tank full, to prevent rust in the metal tank. Fuel stabilizer is just wood grain alcohol. It keeps the gas from seperation when sitting for long periods.
Drain the bowls, steel wool in the tail pipe so small animals don't find a home there, tires off the ground, battery inside. I put in fresh but cheap oil in, so I could dump it out in the spring. I've heard of pulling the plugs and adding a 1/2 oz. of oil, and replacing plugs. But I didn't do it. Then I visited it, shined it up, and talked to it on dark stormy nights till spring rolled around.

Thanks new2riding. Those are some good ideas to make the after-winter start up alot easier. Sounds like you have a pretty good relationship with your ride. Maybe I'll try talking to mine, maybe a poem or two, to see if that gets me anywhere.
