45 min ok, then went full throttle.thanks for any suggestions.

So when you throttle down with the dash control you still have full power like the normal full power or over revving like it's gonna fly apart...????

If it's the normal then check over your linkage where it hooks up at the throttle plate. Something is off.....

Let us know Mon Ami ~!~!

It seems to run at max rpm. May e the govenor linkage is stuck

With the throttle linkage at idle the rpm is max. What I can see the with cover off, the linkage is hooked up and moving . Throttle movement doesn't affect the rpm at all

Yes something is amiss with that... Boo Boo usually will pop in with some links maybe tomorrow when he sees this thread....

I don't know what style of choke you have on yours... Is it the seperate choke lever or the choke is activated when throttling all the way up ??

I have a good friend in Riley Indiana which is not far from Terre Haute.. Are you close to him in that area ?? ~!~!

Did you try adjusting the governor on the shaft , sometimes the governor arm will slip on the shaft , had it happen . Procedure is to loosen the bolt holding the governor arm to the governor shaft, set the throttle to wide open , turn the governor shaft clockwise using a 1/4" socket or wrench as far as it will go and hold it there at the same time hold the governor arm fully clockwise and tighten the bolt on the shaft making sure the bolt is tight, torque spec is 130 in. lbs.

will try that. thanks again for the info.lb

Here is a video on adjusting the governor, the guy IS a Comedian, BUT he's a VERY SMART Tech., skip to the 3:00 min mark when the serious part starts if you don't care for his skit .....

Sounds to me like the "butterfly" plates aren't closing, you may have to check that the linkage is indeed closing the plates.

Yea Boo Boo he might have lost his plate ~!~! Those tiny brass screws come out sometimes...........

Something is going on with his throttle setup somewhere if the plate is OK... Boo pop a link up for his setup...

Problem is we aren't there to SEE what his linkage looks like, could be the governor springs are in the wrong locations, or missing ...... the earlier video he was sent, shows how to install the springs and linkage, we don't know anything about his carb .. BEFORE his first post.. did he rebuild the carb, did this happen all of a sudden, are all the linkages there an installed right, how much experience with carbs does he have ??? maybe the main jets fell out, I have several cleaning / O/H videos but little on the actual linkages they could be bent, missing, shaft springs broken or missing, ... ???? MORE info & pics would certainly help,

BY watching ALL the videos you can learn a great deal about these Nikki carbs ......EACH VIDEO HAS USEFUL INFO !!!!

Thanks Boo ............ Yes he can glean some info from those links ............

thats great thanks.lb

I don't know the engine but can one pull the air cleaner off and with a flashlight, mirror or camera see if the throttle plate is open or closed? If the screws are loose on the throttle plate it can wiggle when open and refuse to close. Also some throttles have springs that pull them so while the throttle may seem like it is moving, all that is moving is tension on the spring. Return springs break too sometimes. I would do all my checking of the throttle plate with the engine off and the key out.

They are also known for the governor spinning around on the governor shaft rod which is made into the block and not repairable. They spin and cut grooves in the shaft then the governor quits or breaks.

No reply on whether or not you have resolved you issue with the 26 hp running at wot yet. If not here is a method I use to determine whether the governor gear inside the engine is blown. In photo 1 I turned the governor shaft fully counterclockwise and placed a nylon hose clamp over the shaft and positioned it at 12:00 c'clock and put a mark on the case. In photo 2 I rotated the shaft fully clockwise and put a mark on the case in that position. If your shaft rotates to the mark shown in photo 3 the governor gear in the engine is blown and will need to be replaced. Attached are 3 photos , hope this helps.
