also try some other fuel.
if the engine don't idle try to puss the crank down from the pinions,if the engine idle for more then ,you probably need bearings.
and last check the orings.
Gregory from your explanation it may not be the bearings, because the plays is very small, barely noticeable. I have also placed some red sealant around the carb for additional protection

I will try the pushing of the crank, thanks

+1 for sealing the carb base. On mine, I found that I had to press down very hard on the carb when tightening the pinch bolt. Even then, I couldn't get reliable contact all around that thin o-ring. The motor would be impossible to tune, adjusting HSN or LSN would not produce the expected result. So, replaced the o-ring and also put a bead of sealant around the carb base. Problem solved, but then had to re-find the baseline needle settings since I had moved them all over the place in my previous hair pulling efforts .

jelayne if the play is so little isn't the bearings.maybe the pipe.have you try to clean it inside?just borrow a pipe that works well in someone else and a carb too.

keep us informed!

Running brand new gallon of 25% Maxy, well I hope it is new.
As Gregory mentioned, your problem could be in the pipe, swap it to a 2607, re-tune and post here your end result, it will give you headaches in tuning your engine if there is a small silicone gasket that got stuck inside the pipe.

I have a problem with my 2607 pipe.... We had talked about it in this forum, it had a piece of gasket in it, I could see it on one of the chambers,and I tried to blow it off with a compressor, and thought it went away as I no longer saw it.

Recently I tried it, my motor revved nice at first, and I put it on the track, drove 1 lap, and bogging sound came again, and it stalled. I tried to fire it up several times, and it was stalling immediately just like the motor was way too rich... I changed the pipe and problem went away.

So, anyone knows how can I solve this problem?

Once you see something in the pipe, you should really use some kind of liquid to try to get it out. If you blow it out with air, you might not see it fly out. With a liquid, you can pour it into something to see if you got it. You can try water but I would probably try something like alcohol to break down the oils in the pipe. May make it easier to get the object out. If using liquids don't get it out, you can use compressed air but try to blow it out into something, like a bucket.

or use the best of both worlds, an air comressor and a bucket of water after soaking it in alcohol

I tried water several times, but it just made 1-2 laps before problem came again.
Ill try the alcohol too, but Im hopeless
Maybe I should try putting it in boiling water...

I had one I couldn't get the junk out of also. I finally cut the pipe in half just to see if I was crazy or if there really was something stuck in there. Well, I wasn't crazy.

If you have access to an oven cleaner called EASY OFF (brand name), spray it inside the pipe and let it soak for half an hour, it will significantly soften the piece of silicone/rubber seal that is lodge inside the chamber (silicone/rubber seals falls apart when soaked with EASY OFF) then flush it out with water and compressed air, hope this help, might have to try a few times until every single piece comes out.

Hi Guys today I did some testing on my engine issue still the issue continues...

Today test :-
1. Tried new fuel same 25%
2. New 2607 Pipe
3. Went to the Hard NT1 Clutch spring(slight performance increase)

After all the testing, the car was still sluggish at pull off, but down the backstraight it was really fast. Coming into the straight away I was slow but as it got down the straight speed was up.

Also rebuilt clutch as for NT1 default settings, basically running at stock except for today's spring change to HARD.

Any suggestions ??
