Since your heater is a Flue-Less Or Vent-free (as it's called in here in the US), I suspect it needs a thorough interior cleaning. This generally is the cause of "smelly" heater. Keep in mind, flue-less heaters use interior air for combustion. So, whatever is floating in the household air (dust, lint, pet air, etc) eventually gets into the heater and clogs it up, causing incomplete combustion and odors. In addition, fresh paint odors are made worse by the heater. Rug or carpet cleaning products will do the same thing. Even days after they are cleaned. Paint smells may last for a week or more. During these times, the heater should be turned OFF and the house allowed to air out, whenever possible.

All heaters, whether they are flue-less portable heaters like yours or a vented model, should be professionally serviced annually. Usually in the Fall, before firing it up for the Winter.

In case you have misplaced your Owners Manual, I have included a link to it, that you can download and print for future reference.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

Not enough data in computer for emissions testing

Has the battery been disconnected, or has it gone dead? Every time the battery is disconnected, all trouble codes are cleared, the check engine light is turned off, and all system monitors are reset. For the monitors to get back to a 'ready' status, the vehicle needs to go through one or more (sometimes quite a few) drive cycles.
When you go to the emission station, they check for codes, AND also check to see how many of your monitors are in a 'ready' status. (This keeps people from disconnecting the battery, and thus clearing any trouble codes, in order to pass emission tests).
If you have not disconnected your battery for a while, but the monitors are still not showing 'ready', you need to have a qualified shop check out your computer and other electronic systems.

Vehicle inspection, pass primary emissions test but failed high idle test HC ppm 559. standard is 220. man at inspection said was missing at high idle,what can cause that??

First either replace or clean the idle air control valve.You can clean it with a non-chlronated brake cleaner and wire brush.Then take the mass air flow sensor off and do the same but don't use a brush just the cleaner only.

The generator, or dynamo, fits onto the back fork bar of the bike. The top, which rotates, should be close to the tyre of the back wheel. There's a little lever which you press downwards. When you press it the dynamo moves in against the tyre so that when you're cycling the movement of the wheel causes the top of the dynamo to rotate. To stop it, or turn off your lights, you pull the dynamo back out from the tyre. You need to adjust the dynamo so that the top of the dynamo makes contact when the lever is pressed but doesn't when it's pulled back out.

Normally a dynamo has only one wire which connects to the lights. You need to use lights designed for it. This carries the positive current. The frame of the bike usually acts as the negative. Some dynamos may have 2 wires. In this case the positive connects to the centre of the light and the negative to the outer.
