All problem fixed. When doing the sprinkler valve mod, I did not put the rod back in. Last night I put the rod back in the diaghpram and bent it and everything is working perfectly. I launch a whole spud probertly 250 yards. Lot better then my old "combustion" chamber. Just want to thank everyone that has helped me out.

Thanks.

My problem is cured now. Dissassembled the mod'ed valve and insterted the guide rod and everything works great. No more horn sounds with me. Just want to say thanks to everyone that has helped me out on this problem.

Thanks

Hello,

I will let you in on my personal experience with honking.

I built a gun and ended up doing a lot of cutting. I did not clean up the shards of pvc inside the gas chamber. When I fired the gun, the shards flew into the valve. When I took the sprinkler valve, the rubber seals had pvc all over them. I cleaned them and put a little air tool oil on them and it fixed the honking. Kthxbai.

Thanks, I fix the honking by putting the rod back in the vavle. I also had the same problem with pvc shavings as you did.

Thanks for the reply,
