    Hi all I just got my bike finished I use a schwinn lannok beach cruiser and an 66cc skyhawk engine ,runs great starts every time.I took it to orlando from were I live in kissimmee was a great ride about 30-40 miles round trip. engine seemed warm but not hot i was impressed, but one thing every so often it would kinda bog out, like it was smoothering itself, humm let me better explain ,if I gave it gas it would kinda sputter and slow down so if I cluched it and reved the engine a couple time it went away or if i just let off the gas very easy and then gave it more very easy it kinda cleared up I dont know like it was getting too much gas and drowning something to that affect any advice. o and my engine has a 2 cables a throttle and a choke cable the choke is not on, its like connected to a shifter that i never use zip tied:bowdown: to the side .

    Two strokes will tolerate running rich better than four strokes but while the engine seems to be running ok, power will be substandard. If you run a two stroke sloppy rich, it won't warm up to a normal operating temperature. Sounds to me like you need to lean out your fuel / air mix but be careful, too lean will destroy your engine.

    usually stock standard with the normal exhaust, theyre rich as.

    you have the fancy carb...um, no idea what jet that wants.

    but on the standard carb its 0.79mm stock...i made a jet of 0.6mm. much nicer. ended up going up again to 0.65, may have to find imperial/guage size drill for say... 0.63mm.


    i get what you get too...my ride to work is about 6km... fine. halfway it sorta dies off n gets weak... then picks up and its fine again. ive tuned it as well as i can with the stock carb, with a new pipe... depends on the day and time and i have no idea what else.

    they are one temperamental engine... luck of the draw i guess. so as they heat up etc, clearances change... an engine might go hard when cold but dies when hot... and vice versa !

    they are cheap after all... so unless you spend money on things like rechromed bores...(mine was full of holes when i got it...meh!) dont expect tooooo much consistency ;)

    Engine question

    Hello again i thought Id ask a quick question my engine runs fine and it seems that every once in a while it bogs out, I:helmet: can be going fine but if i give it gas seems to die out like im flooding it ,but if i clutch it rev the engine a couple times or just let off the gas it kinda clears up is there a problem or ? I got the 2011 engine with the choke on it but i have never used the choke starts everytime .
