« on: May 01, 2009, 06:01:42 AM »
Hi  
well im glad to find a forum for this

first question i bought  this odyssey had some issues the rear brake cable was seized and odyssey wont move  i replaced the rear brake cable i hit the brake odyssey wont roll but how much drag should there be to hold it when you start it or is that what the ebrake is for

second question : when i start it seems to run fine but then idle will increase rapidly as it warms up

any help on this would be awsome

It shouldn't roll unless you have it idled too high or your clutch is not disengaging all the way...
As for the idle, several things can have an effect on it....Compression, air screw adjustment, and air leaks....Sounds kinda like you may have an air leak somewhere IMO....

The air screw is the same as the mixture screw...Gently run it all the way in until it bottoms out, then turn it 2 - 2 1/2 complete turns out.....The mix should be 32:1 if you are using a high quality oil...
