heater hose connection By dryshave (Read 3,201 times)

I'm having a brainfart and for the life of me can't remember where the outflow heater hose (routed from the thermostat - connected to the carb heater) routs to. The hose goes from the thermostat to the carb and the outflow goes to?
If I still had the 150 I'd just pop the cover. I've gone through the service manual over and over and still haven't found it... HELP!

First of all it's not needed and scooters today don't even have it hooked up, why they still put the hose connections on the carb is beyond me? But which scooter and engine is this? I do believe the vertical engine hookup is different from the linhai version if you really do want to hook it up.

sorry CN250 Helix 1985 - the manual says it's for warming up the carb in cold weather. I don't really need it as this ride won't be seeing anything except sunny warm days.

It's the steampunk scooter engine - sorry haven't updated photos lately - but mostly waiting for parts to come back from the machinist.
Third time's the charm on the wiring harness - finally got spark to ignition - turned out to be a "cross design" problem (I made) with the Helix wiring diagram and the CH250 diagram), so I ended up redoing a new helix wiring harness.
Looking to do a full fire test today.... so I've just plugged off the coolant outflow for now.
Will shoot a quick video of this momentous event as it may prove handy in case something goes wrong... or just another entry to funniest videos. Thx

You should have a inlet and outlet port on the carb warmer, generally it's just bolted on the side of the carb. Route the little hose from the thermostat cover to one side (either one) and then put a short piece of hose from the outlet on the carb back to the thermostat cover. Make dang sure you use good hose and clamps.

There's only one port coming out of the thermostat cover and that is routed to one of the outlets on carb warmer. I could just use a t connection I suppose... very puzzling. I can rebuild a scooter from the ground up, but this has me stumped!

Your carb most likely looks like this and that plate with the two ins and out for warming the carb. You can just leave them unconnected and plug up the hose coming from the radiator.

that's what I thought... have blocked off the tube at the source.
Had the old girl running over the weekend... sounds pretty good just on the original muffler... waiting for the exhaust man to get back to me with the new tailpipe.
Have the tailpiece back from the machinist... WOOF! Taking the other pieces in to be polished... won't post new pics until they are all back... the tailpiece is PERFECT! Will update the post next week with new pics and end of year wrap up as I need to get on the christmas gift list... ALLEYOOP I have you down for a ride... thx.
