Well guys I hope you can help ! I am at my wits end with this C6BB7T . I bought the motor from A-Main with the matching pipe .

Nothing wrong with the motor at all but I just can't get this thing tuned in .Driving me crazy .

I am running Sidewinder 20 % for fuel ....fresh ....RB#6 plug

Followed the nessacary break in procedure.

Settings were 3.5 on hsn and 5.5 on lsn...........this was very rich during break in so it was difficult to run the motor at 4 turns on hsn for break in but but now after the recommended procedure I am between 31/2 to 3 1/4 turns on the HSN which is a great smoke trail at like 85 to 95 % power . A little fat maybe but safe and very fast .

Here is where I think the issue comes in but I have heard so many opinions at this point and read so much stuff on the internet my head is spinning right now ...LOL !

I set the idle gap at .8 mm as per the RB website which I know is appox. but close ..............at 5.5 turns off the bottom on the low speed needle the car holds a steady idle for about 20 to 25 seconds before it drops down as the crankcase loads up . This is at about a 215F temp on my raytek gun which I know doesn't mean a whole lot but still a reference point somewhat . So this is all while driving this car around the pits before my 5 minute qualifier .

So I fire up my car about 3 minutes before I hit the track ........throw it down and go about 3 or 4 laps before for they call us in to refuel before the sound of the tone . Car is running good !!!!!!!..........temp is like 240 though .........and I hate to talk temps because I know you shouldn't totally go by that because temp gun vary so much .

So about 2 or three laps into a run " maybe 2 minutes run time " the car stalls ???????

Here is where all the opinions come in . Lot of guys say its too lean .............so it bulids heat as it goes and eventually stalls . WHEN IT DOES STALL IT IS WHEN OR ABOUT FULL THROTTLE IS APPLIED OR JUST AS I LET OFF ...TOUGH TO TELL BECAUSE THE BUGGY IS CARRYING MOMENTUM AS I BLIP THE THROTTLE AND THEN THERE IS NOTHING ".

I run out to the track and grab the car and it is wicked hard to start if that tells you anything ??????

So once in a panic I lean the bottom end out thinking it was too fat and all the residual fuel in the crank case was coming up through the motor when full throttle was applied and that included with HSN setting just flooded the motor ...but if that were true it would happen sooner ...like before I even put it on the track right ????well when I did this the motor stayed running but the performance was terrible .............staying at high idle after the front straight ,reving up over jumps ........it even has that weird lean machine gun studder at idle . Obviously too lean .

Tried a pinch test................ when I get the low speed to like 3 to 4 seconds before the revs come up like alot of guys recommend the car almost alway stalls because it is so rich and I am forced to lean the hsn out to get the car to run down a straight away to get it to fully cleaned out .

I am no expert at this but I do have alot of motor experience ............I'm just totally lost here .

Thanks in advance for any help .
