I am trying to get my grandpas old three wheeler running it sat inside for about 15 years then outside for anouther 5 years without running and was running when stored pull start is stuck and electric start button won't work however I can hook jumper cables up to car battery and touch the post on starter and it will turn over and has good spark I put in a new spark plug and cleaned carb and wouldent run I then bought a new carb off ebay and put it on. Now it will start and run with choke on and seems to sound real good however when I push choke button in it revs real real high also nothing seems to change when I hit the throttle

 

Could be sucking air,jetting could be too lean.On something this old,setting up this long,just start at the basics,change oil,plug,check/adjust valves. An old manual can help you in more ways than one. See if these free ones still work. ATC Manuals

 

Ok thanks Do you by chance know if rear rims off a yamaha 3 wheeler will go on honda 3 wheeler

 

Nope,don't know,but someone else may come along that does..

 

One more quick question do you know if I could take rear end out of honda three wheeler and put it on yamaha 3 wheeler

 

Wouldn't think so,not with out a lot of fabrication work. Just try to repair/replace with what you have rather than trying to cross breeds parts.
