I have a new CRRC 26R engine that I cannot get to start. I have a good spark and the carb seems to be pumping fuel. The problem is gas is coming out of the front bearing just behind the prop hub. With the front bearing leaking like that will the compression be so weak the engine could not start?

You problaby sucking air from the from bearing,remenber this a two cycles engine

Is there a supplier I get a new bearing from?

Crrc are famous for the soft crank case and the front and rear bearing spinning in the case it shows up with a lot of black gunk around the hall sensor area and in your exhaust. The best way to repair is to remove the bearing clean area's get some green lock tite and reinstall bearings make sure you use some small wire ties on all fittings as air leak in the fuel system will not draw fuel.

The first batch of GP26R's and a bad crank shaft and case. Very bad fit and leaked air and bearing spinning. How old is this engine?
The newer version dose not use a gitz seal, just a sealed bearing up front.
Cheers

My engine is completely built from parts (new) I have not had the spun bearing since the lock tile and have new case crank piston, bearings and cylinder replaced ring with a Boman ngk plug rcexl ign. the reeds flat sanded new carb and pulse line. Still have that nasty almost quit on throttle chop needles makes no change. Idle any lower than 2000 becomes unreliable and quits. Timing checked and rechecked at 28 have tried 32- 21 just runs rougher. Used JZ carbon fibre APC form 18x6-19x8 just loads the top end the high idle makes the landing hot and at times safer to kill the ign. I give up! Front bearing is a sealed bearing never had the internal rubber seal like the V2. The case is just to thin heat will distort the case and allow the bearing to spin the cranks are so soft you can write your name on the machine bearing surfaces when they cast the counter weight what ever slag was left in the sand mold stayed there making some of them shakers mine smoothed out when I replaced it. The 50r is worse.
