I would have to say that I am sure that the front bearing is not a issue with leaking. As long as the seal is in place or the shield is not bad you will have no issues with a leaking front bearing ever causing a tune issue. The front bearing can be bad and have a problem with tuning but speaking about the leaking. Think about all the .21 engines that are run on road. They use shields not seals. You can see daylight through the bearing if you look up. The seal from the front is caused by the tight tolerance from the crankshaft in the case as well as the rotation of the bearings and inner retainer. It is moving so fast that there are no leaks. I have seen a bad rear bearing cause needle problems though.And also check the carb for air leaks. This is a cause as well.

Picco carbs leak guys !!!!!!! Out of 10 Picco's your going to find 3 with a split carb body that will leak and not tune...... This has been an issue with Picco for years and years..... Nobody has been quick enough to catch it tho !!!!! The seam between the composite carb body and the metal end bell is prone to leaking..you need to seal this seem with JB weld or sealant of some kind......... every Picco any of us run has this seem sealed and all our Picco's tune as easy as any other motor............ If you dont seal this seam the motors can be difficult to tune, as the airleak acts much like a Phantom leak..it will only become apparent when the motors gets fully heat soaked,,,,,,you will chase a tune forever till you seal this seem !!

Maximo, I have run PICCO engines for 3 years in a row, from the first .12 with the purple head, to a Mega ZX -12, Mega DS II ZX .21 to PICCO P3, P7 off road engine and to the P9 R on-road engine and never encountered a carb leaking problem, you must have been doing something very wrong to create the leak, as msgsr said it did not leak on his RRR and only started to leak when he transfered his engine to his new car, that tells you that it got to be a problem somewhere else.

Now its still winter where I live..but within the next 4 weeks I hopefully will be able to run some nitro...When I do I will make a video of what these Picco's run like before and after I seal the carb body... I think a few of you are going to be eating some Crow on this one !!!!

Any pics of where in particular and how you'd recommend sealing it?
