faster in reverse

[patb069]

It's been 10 months. I took my machine out after rebuilding the entire Maxiv. Literally every nut and bolt has been replaced. I am really ready to flip out. Took it out for a maiden ride tonight and it goes faster in reverse. It does about 5 - 7 mph in foward and a little faster in reverse. What the heck did I do wrong. Please help before I set this thing on fire.

First, make sure your CVTs are operating properly, the engine is revving as it should and that the belt is moving as it should. If that's fine and if you are pushing forward (hardish) on the sticks while in forward without any luck then you may need to adjust the bands on the T20. Start there.

Hi pat, Is the drive belt tight enough. I think u have to jack the motor up with washers under the mounts to adjust the belt tension. Good luck Mike

Pat did you replace the engine ? What governor spring did you use? Engine has to run at least 4000 rpm with belt on to have any speed. I know you had driven clutch apart is there any chance you got the spring a bump to tight? That will make it stay in low speed all the time. Good luck let us know what you find. You will be riding soon!

Hi guys. Thanks for the input. Belt seems to be set perfect. Clutches are working properly. I think Mark may be right. The engine is a brand new 23hp vanguard. The engine does not seem to be turning up revs. I never replaced the factory governor spring, and besides relocating the throttle cable, I didnt play with the carb at all. Is there soemthing i have to do with the engine to get it to rev faster?

Bend the tab the the governor spring links to. Play with it and your throttle until it's revving right. You probably want to get the correct spring from MuddOx as well. I really don't know what the difference is, but Jeff always had me change them on my engines to ensure it worked right.

You can order one from Tiny Tach with a custom length coax cable (unless you know how to extend the length yourself.) I email them for a quote. That way you can mount the tach on your dash and string the wire back to your engine.

I have one (tiny tach) on my max 4 that is standard length and it fits perfectly on the left side of the dash... I've tried the knock off brands in the past and they always have problems with them. 4300-4400 should be a good rpm. Norm..

[patb069]

Thanks fuys. I will be ordering one today. I just looked. I have the red governor spring. Looks like I will need the Rev kit as well.

[msafi65]

The red spring won't do very well briggs # 691507 brown spring. That and set rpm with tach an good to go.

[ARGOJIM]

4300-4400 should be a good rpm. .

That's a tad high for a Briggs.

[patb069]

Thanks for all of the input guys. The problem is the governor. When I manipulated it by hand while driving the rpms came up and the machine took off. George is going to come by and help me set it. I ordered the mini tach and rev kit. Thanks again everyone for the assistance.
