Top speed and RPM
« on: November 07, 2018, 05:48:11 PM »
I have read that 45 mph is the top speed of a “White HT”. I opened mine up on a flat dirt road today and got it up to 33 mph according to the old speedometer. It was at 3000 rpm according to a modern cheap tach. Does this seem right ? The engine is a fresh rebuild and seems to run fine.

Mine was 35 MPH and I had to check with my buddy who has had his HT a long time.  He said that was his top speed too.  Going down a hill he said he reached 38 MPH. :D  I had heard 45 also.

I figured it out. The “economize” valve in the carburetor needed changing. Dramatic difference.

Did you clean yours up or put in a new one? If you put in a new one where did you find it?
