I cant watch the video. What's your compression like? And how does the spark plug look? What setup has it got too? As the standard carb will run a 70cc kit easily with just an upjet.
That's a Naraku carb. Takes 5mm dellorto main jets. Comes as standard with either a 70 (17mm version) or 90 (19mm version) main jet I've got several on the shelf.
I am so greatful for your replys. I have to say I'm 28 and love 2 strokes. I'm not really that new to tuning i have done two projects prior. Piaggio zip and Peugeot speed fighter with good results too. What this yamaha areox has is ( i bought it this way ) it has a tnt 50cc cylinder with a laser exhaust ( i've never heard of this brand ) with the carb in the photos. Its been running with no air filter as the original box doesnt fit the carb. There was a gap. I fixed this with some duck tape temporarily to get it going but it Splutters and kinda sounds like a miss fire but like more air pops than a typical miss fire. Compression seems okay. It will idle for ever! But if i try to ride it. It will pop and splutter without the airbox or with it and go no where The carb has a 84 main jet. If that helps sorry for the long reply.
Well the kick start is not easy to push down i definitely could not do it by hand. I don't know about the spark plug i will buy a new one tomorrow and get back to you. It will idle tho and when it's warm it will fire back up straight away. I think it has something to do with the carb or like you suggested th cylinder. The person i bought it off said it just had a new engine rebuild..... But you show me one 2 stroke ad that doesn't say that ahaha
Hahaha yeah they always say that... but measure your compression. I don't know the difference between a worn piston and a new one and I do it for a living. Sounds like maybe its a little lean? If it starts easier when warm thats a sign. Try a new plug first though, as its the cheapest thing.
Oh wow i'd love to to something i love for a living. Instead my job is repetitive . Okay so I'm going to get a plug and report back to you with the results today.
This was the spark plug. I have replaced it. But..... some how i think this is not going to solve the problem. I think I'm going to but an open air filter and up jet it. I think it's getting too much air. What size jet would you say i should start at ?
That doesn't look lean to me. Looks quite spot on, maybe a little rich really. Have you checked the compression yet. You can put a bigger jet in, but I suspect it will be worse. Get a sponge filter. Thats the best type you can use.
No i haven't i dont no how to check it... Taking off the piston to check the dimensions seems abit of a task
Conpression tester tool. Take out the spark plug, screw in the tool, hold the throttle open and turn the engine over. Its a great tool to have if you plan on owning a 2 stroke for any length of time. I dont think they cost much.
