Thanks for the feedback. Unfortunately, I haven't touched the RAV valves, only the carbs. I also took a lot of pictures and video and scoured through every frame trying find these items. I've also searched multiple diagrams.

Please help me identify the location of these 3 items. I just finished rebuilding these Mikuni BN46 carbs and I can't figure out where they belong. They don't go to the high, low, or idle screws.

After running to Northern Tool and Harbor freight to purchase a small assortment of drill bits from .5mm to 3.0. I broke out the micrometer, did some measuring and found the best fit bit. Measuring .315" which equals 8mm (Jet size 75 -> 80). So with the accelerator pump disconnected, I'm going...

Looks like I've fallen victim to the torn orange accelerator pump valve. I barley touched it and it ripped off. So I guess I'm removing the pump and fuel line going to it... It seems that census on the forum is to change the low-speed jet by 5#'s. Since I have the 951, I believe my stock size...

I stand corrected on the 2-cycle oil. ToughAG sells (4) gallon bottles for $107.99 which includes shipping to NW Indiana.

Good catch! Thank you! I found another site that provides a discount when buying four bottles. $147.50 Your Premiere Source for Ag Lubes, Parts and Supplies - ToughAG

Now I can enjoy wrenching on my ski!

Looks like it's on sale at O'Reilly's for $27.99/gal Thank you!

Do me a favor and post a link to your preferred synthetic oil.

I've been reading over many many posts here within the forum on the 951 engines. Lots of quality information... I held off on the installation of the carbs after doing a compression check. I got 120psi on both cylinders and at 160hrs, I'm wondering if I should go one step further and replace...

Discovery made: When I was trying to start the motor by directly running a hose from the carb to a fuel mix, I'm pretty sure this was a flawed test as I am finally grasping the details of this 'pulse' thing. After removing the carburetors, I am just understanding the difference between the fuel...

Another thing I stumbled across, it appears that my 2 cycle oil is leaking with a small stream dripping down.

Well I removed the carbs and didn't see the results I was thinking I'd see. The carbs were obviously previously removed with all the permatex all over. Although, it wasn't inside the carb, nor was any dirt. The accelerator pump diaphragm had enough fuel in it for two squirts. So now I'm puzzed...

I was able to get the lower nut off the exhaust by making my own wrench. I just heated it up with a propane torch and bent it. Now I need to figure out which carb kit to purchase and then clean up the grime. I can't stand working in all this sludge.

Followed your suggestion and the carbs would not pick up the fuel. Inspecting the inside of the fuel line, it's caked with a green powdery substance. I've read a few posts to discover this is common so I'm replacing the fuel lines, filters, and rebuilding the carbs. Which leads to my next...

This "pulse' I assume is a vacuum? And when this occurs, is this vacuum created in the carb diaphragm? I'm trying to troubleshoot this and wondering if I start with testing a potential leak at the pulse nipple of the carb. The manual shows that it's supposed to hold 4lbs for 10 seconds. At...

I just purchased a 2000 Rx951 carb'd After reading the repair manual, I don't fully understand how the fuel is 'pumped' to the carbs. The manual mentions accelerator pumps but no dedicated dedicated fuel pump unless you have the injections system (Di). Do the accelerator pumps on the carbs act...
