No tickover Sh1/20
Posted: Tue Apr 21, 2020 1:00 am
Help please...
Finally got scoot li 150 started after rebuild fitted a New scootopia sh1/20 that was set up for a 200 but changed the slide for a 150 set up and atomiser to a 5889-4 with 102 main jet, choke 50, pilot 45.
When choke Is put on it revs fast.
Once warm I flick off choke and it dies, it will start again rapping the throttle open but if I can’t get the throttle opened up quick enough it dies again.
Set the air mix screw to 1.5 turns but to be honest when I can keep it going and I try to adjust the air screw to get it to idle it makes no difference. Tick over screw is slightly lifting the lever but again makes no difference wherever I set it.
Did a leak down test and all was ok
It has been strobed and set up to 19deg but not sure what revs we’re going through it as I just managed to keep the throttle open enough to get the strobe on the flywheel.( so presume reasonably high revs)
New BGM stator fitted and checked all seems ok, CDI is a Scootronics with leds, flywheel Indian but lined up all pickups to stator. Sorry trying to give as much info as possible.
So basically nothing at 0 to half throttle and cannot get it to idle.
Ordered loads of main jets ( from 90 to 110) also got a 41 and a 50 pilot if any would help and a few atomisers 5889-2 ,4 and 5.
One last thing the only place air is leaking is from the exhaust joint as I noticed fumes coming from there when I kicked it over exhaust is an AF rayspeed 42mm I have some sealant for that but not put any on yet.
Sorry to bore you with this one, just need a few pointers, I know it’s a bit of a science.
