I did change the pilot jet. It did help.

I changed the setting for the needle to en-richen. I added a washer, but it didn't help. It was easy too large of a washer. Made it worse while not adding and fuel to the top end.

I've since changed the washer to only a very thin one. It did help. I cannot find a #106 or #107 main jet.

I ordered a set of 18 gram sides. I'm currently on 16.5 gram rollers.

When I get to 7100 RPMs I am at 47 mph. No wind, level ground. If I install the 18 gram sliders it might not do what I want.

I swapped, rollers to 15.5 gram rollers. If I can't get to max RPMs now, going down in weight by the 1 gram should give 500 RPMs. It did help but still cannot get over 47mph.

I am going to try to move it back up to the 18 gram sliders when they come, try to get a larger jet than #105., I am also noticing the belt tension was ok, but when I checked it for tension, the back pulley was allowing the belt to move down in to pulley face easily. I am ordering a 1000 torque spring and a longer belt again the 842. If the tension is corrected then the belts should be tight again. and the larger belt will give full range of motion.

I'll see what that produces.

Anyone with any thoughts would be great

Do one change and check results..

Also if I can get mine up to speeds. Getting closer. Got 47 mph.

I just blocked off mine completely. Really helped me.

I found a post by Alley and he suggested when the surging is from the auto choke being stuck open block it off and put it back on or replace the auto choke. I'm going to do that. I've taken that carb out, I'll run the other one for now until I get the adjustment done.

I did replace the variator with OEM and the rattle from the rollers is still present. I have no idea. I'm thinking of getting a new clutch assembly. Not performance, just new. I took this one apart and cleaned and re-lubricated the outer circle bearing, then replaced the inner needle bearing.

I don't that's what's wrong but,. Nothing else was touched.

So, I have been driving it on and off. The problem I am seeing right now is that at idle I get surging that I wasn't noticing before. It's a lean condition apparently, but from where? I research a couple of things. I am going to pull the intake manifold and make sure the gasket there is ok. Then spray again all over. Water, wd-40, choke cleaner, etc,...

The good, it's not bogging currently. If it stops the lean condition I should be good to go and should be able to get full power and get to 55mph. I hope

Right now I've placed it on the setting for no bogging. I then just upped the idle screw, and the air fuel mixture. I'll test on the way to work. Make adjustments on the way in. Report back.

Edit, this set up was not working correctly. I put it back to the 2nd to the last leanest setting. I couldn't take off, as it was too lean, no power at all, and would die. Moved the clip setting from the leanest, that fixed it.
