Hi Martin gad you stored it out sounds like its running great. A classic mistake which i still do myself is changing more than one thing it could be and causing another problem. Signs of cutting out after full throttle at tick over fuel in the bowl not high enough to reach idle jet but i'm a bit late watching your video. These small engines are so sensitive to changes spark plug type exact gap ,air filter and airflow after re jet , belt changes and springs will bog as gearing changes at wrong engine rpm. The biggest lesson i have learnt is don't always think because its new its not faulty, I had a brand new carb and still had problems changed everything coilpack, stator and flywheel, pickup. reedblock and reeds all the expensive stuff only to find it was the new carb that was faulty. Keep those video's coming love watching them.

Hy Paul, what do you mean by having the air box back on correctly? The carburetor should work fine even if it s disconected from it, shouldn t it?

Air leaks can lead to a weak fuel/air mixture which in turn will affect performance and could potentially damage the engine if running too lean.

Nice job thinking your way through a frustrating problem. Had the same problem with a moped I worked on for my sister-in-law. To start with someone had the thing hydro-locked with oil pouring out of the fill hole when it was not running! I actually got it started after fixing that problem and messed around with it for a couple of days and finally got it up to 45 mph five times in a row without it bogging down and was doing back flips when I got back home! When I gave it back to her I told her I wouldn't be disappointed if I never saw it again! So far she has left me alone. I guess she got the message! Frustrating little things.

@jackfairweather199 6 жыл бұрын

Too much oil in the crankcase won't allow the engine to turn over. Can also happen if you have a carb that is malfunctioning and dumping fuel into the crankcase. The fluid pressure "locks" the piston in place thus no start. It can also happen with coolant in a liquid cooled engine.

@stevehill4615 6 жыл бұрын

glad you got the fuel starvation sorted --- i think you might get a little more performance by reducing the main jet to a 58 (i was told as a rule of thumb to add 5 to the main jet size when de-restricting ), a 56 mentioned elsewhere may work but with the aftermarket exhaust (is it a geovinci?) might make it a touch lean at full throttle ----- if you want to test if slight leaning out of the mixture improves the performance, try dropping the needle 2 notches (assuming a 5 notch needle) which will give an approximation of what the 58 main jet will be like.

Martin I had this on my yamaha jog and although it felt like fuel restrictions it was because it was getting too much air through the air filter. It really felt like fuel restrictions and the petcock had a diaphragm in which was worn out. However once it started it ran fine.

Just for the heck of it, you should try the 65 jet you first had to put in the carburetor. That should really spice her up. Thank you, Martin.

@stephengardin2423 6 жыл бұрын

You're correct. The problem will need to be sussed out. A bigger jet again will allow for finer tuning because the volume of air has increased by over100%. The spark plug looks very nice as far as colour is concerned. I don't recommend chopping the side post of the spark plug off. Yes, it will increase igniting strength however, it will dramatically decrease long-term reliability. For racing purposes, it works out great because a race isn't that long and sparks are free to the teams generally and their ignition systems are many times more powerful than what is found on the street. ;)

I personally would have left the bigger jet in place and run the engine around a bit to see if that improved the plug colour, as when you had fuel in it in between the stops, the engine sounded quite sweet to my ear and very lively. The problem with rerestricting it with the bigger exhaust is the air-fuel pump balance will be inequal and I fear you will have lumpy performance.

@retrorestore 6 жыл бұрын

No lumpy performance Ian, it runs as sweet as a nut with no flat spots. I drove it 20 miles and it runs great. It has the bigger jet in and the restriction plate out as I said at the end of the vid.
