Title: tvt 691 not running on both cylinders
Post by: ciarlo on September 21, 2016, 06:45:17 pm
I have a tvt 691 with the ohv carbs and arc flywheel. It starts fine. When I give it full throttle there is a dead spot just beyond the idle until about 1/2 throttle. Then it revs up but doesn't always pick up the second cylinder.  I have stock emulsion tube and stock jets. I have looked online but haven't Ben able to find any new blue emulsion tubes. I was told the this engine idles on one cylinder and then picks up the other cylinder at higher rpm. I'm new to this so any and all help would be great.

Sync the carbs.

I tried searching the forums on how to sync the carbs. Mind posting a link on instructions?

Best bet is to get a paper manual, that way it is always around for reference. And, you can write notes and such in it.
