So guys, question..
Have I diagnosed this correctly if I think it is a leaky front bearing?

-P5XLT engine freshly pinched, only break-in done, new conrod, good crank
-irratic idle, sounds like motorboating "woooorrr wooorrr wooorrr" rather than one continuous stable sound
-at first engine ran fine, but towards the end of the day kept choking, despite being ran sufficiently lean
-seems to be carburated fine, but then after 1/4th lap on the track chokes for no apparent reason
-engine has truckloads of compression obviously
-front bearing is cheapo €4 ebay bearing

I'm thinking this means the cheapo front bearing has let go? Even if it has only less than 1 gallon on it.

I just thought I'd save a few $$$ on the cheapass ebay bearing, actually I got 4pcs for €4.. so that should have been a clue. Lasted 2.5-3 litres, so not even a gallon! But hey, lesson learnt.

Have ordered proper bearing now from Amain.

dare I say this on the nova thread but the front bearing from reedy is actually very good in its sealing capability also

Well the thing is, to install the 17011 then I need to tap the front of the collet on my Hudy tool

Other Q, got a Nova carb off P5XL that's been laying around on my table for about 2 months, now when I try the action on the slide it's like it has a notch sort of halfway, what would be the cause of this? could there be any oil gunked up, or does it mean it could have taken a knock or something?

undo the barrel stop screw (idle) and remove the barrel , look around the slide recess's where the stop screw rides for damage . often times some good "lawn darts" while on throttle will wreak havoc on the slide barrel as well as the rod , the piston , etc. , etc. ;)

take it all apart and reoil it anyway Elvind , it should be smooth again
