Default Re: BGF engine questions

That sounds like the bgf 50 I have, no markings what so ever. You may want to check to see if the piston clears the port on the intake side at tdc, on mine the plston blocked about .250 in in the center of the port. I removed the piston and did the mod. found in the performance section of the forum and that really helped that engine a lot.
Your results may not be the same,Greg
