Josh at tec service was unhelpful.
He said "we import from China and I have no control" They don't
Unit won't idle. Carburetor piston inserted wrong, vacuum leak
No info on carb. Not sure about choke: witch doesn't seem to work. Maybe a vacuum leak
Josh says there is no mixture screw only an idle screw (which doesn't work.)
It has to work, again vacuum leak
By the way, no info on this carb. Easiest to go through.
Why would someone sell a kit without installation instructions?? Most do not, I get them with all my kits but they are supplied by most vendors online.
All the mechanicals are ok.
Problems with getting it running. Have used 16:1 mixture and it SMOKES.
Was told to use that for 1st gallon of gas then change to 20 or 25:1
20:1 to start with then go to 32:1 using a oil designed for air cooled engines.
Has any one had problems with installation?? Yes....nothing new, nothing that can't be fixed.
Any help would be appreciated.
Contact me here or at
Thanks for your help.
(Probably should have come here 1st !!!)
