Small Engine Carb Repair Tool: Mini-bike Go Kart Scooter Moped Racing - Answered Questions & Fixed issues

Hi Nigel. Not an expert by any means, but the information I can find suggests .018" (18 thou) for the points gap. There are two ignition types for these engines, a magneto (old style) or a CDI (Capacitor Discharge Ignition). Not sure if that has points at all. To double check, the points should open at 20 degrees before Top Dead Centre. As the cam is fixed to the crankshaft, the points gap will affect the timing. Regarding the low oil shutoff, it's not mentioned in the data I have, so maybe not. You can check though. The oil level sensor should have 1 or two wires coming from the crank case. one going up to the coil primary. That wire is grounded when the oil level is too low. If you think this may be stopping the engine from starting, you can disconnect it. But make sure the oil level is correct! Enjoy...

Look.. why don't u try online some websites deal in it real time.. along with solutions to problems how to repair fix service nd all let me know if u need some help in this

Hi there's this website something like reliable-store and it is very amazing for manual for repairing servicing anything someone on fixya recommended it to me and I thank him even today They have full manuals and it's verrrrry cheap and mine I got free in offers 3rd time I also had an issue with the file so the girl replaced it in 30 mins there is one more but i don't remember its name it was 2 years back bitman something link this Try it out brother

check for spark probably a bad coil

Sounds like a damaged or badly carb'd valve or a sticking valve maybe, check are your valves opening and closing properly. thewad001

The larger the gear on the engine shaft and the smaller the gear on the drive axle the more speed you'll get, I hope you're thinking about top braking power for it as well lol good luck.

Look at these links . http://www.m-and- d.com/http://www.alamia.us/Briggs_Parts_Briggs_Carburetor_Briggs_Filters_Starters_s/969.htm?Briggs%20%26%20Straton http://www.partstree.com/parts/

Here is a couple of links to check out and book mark for small engines. http://www.m-and-d.com/ http://www.alamia.us/Briggs_Parts_Briggs_Carburetor_Briggs_Filters_Starters_s/969.htm?Briggs%20%26%20Straton http://www.partstree.com/parts/

Get a compression tester and turn it over 5 times. See if you reading is above 90-150. Anything lower it is the cylinder wear. Check for bright blue spark and maybe dirty carb too. you tube videos can help you fix either possibly.

if it is electric start you need a new starter solenoid if it will not turn over on the kick start then your engine is seized to solve the problem for this remove you spark plug and put some thin oil down there and let it soak for a day or two remove the side casing and turn it over on the flywheel nut until it is free give it a few more turns and get the old oil out then put your spark plug back in and start it

It's a pretty big job. You need to be competent (and confident) with tools as well as diagnosing and repairing gas engines. Without knowing the details of your scooter, the overview is this: 1) Remove the carburetor (if mounted to the cylinder), exhaust pipe, cylinder head, cylinder and piston. 2) Have the cylinder bored out** to provide the correct clearance between the cylinder and the piston (if different from the scooter manufacturer's clearance this information should be provided by kit manufacturer). 3) Modify the head (more machine work to reshape the combustion chamber to work with the larger bore). 3) Reassemble. 4) Modify the fuel system (usually a carburetor) to correctly fuel the now larger displacement engine. 5) Get the new set up running and then tune it to run properly without damaging itself from an incorrect fuel mixture.

** Some cylinders are aluminum with a steel sleeve that forms the bore that piston runs in. Some are aluminum with a thin nikasil coating on the aluminum bore. These will be much more expensive to bore out as they will need to have the coating replaced after being bored out.

NO THEY ARE DESIGNED FOR SPECIFIC VEHICLES

Probably done by design to stop a joyrider jumping in and driving off. Contact Avital direct. FWIW, remote starters are a whole lot of trouble. Let me know when you burn out your first starter motor because it does't release, or it locks you out and won't let you start.

I got this free Pdf manual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 yearsmust try this bitman and reliable-store. Both are good

hello u will find a lot of wiring diagrams and circuit diagrams help books and stuff like this .. im a frequent buyer there since Im a mechanic so take help from there

Gravity feed tank need no fuel pump.....

If it is an electronic accelerator pedal you have, perhaps poor contact on the wires/connector on the pedal. Lay down on the floor, and check if the connector is in it's place and no loose cables. I had same problems with brake pedal and signals from that one.

Hi, If you did the usual testing (comp,Carb cleaning, etc.) then I would go to the electronic ignition box if it has one. I've been fooled before. Checking for spark, wire off, or plug out, isn't the same as a plug under compression , Good luck.
