A really great result so far Brian  :whoohoo:  congratulations   :cheers:

It will be a fine runner after a bit more running time and hopefully doing great on the Hit'n'Miss function too.

Enjoy your watching  ;)

Someone asked if I was going to give any information about the new carb that is currently on the engine. This is the carb, and the download link will get you all the details from a web hosting site.

This video shows a bit of close up detail on the face cam. I had never built a face-cam before, so I'm rather thrilled.

I have spent a couple of hours this afternoon "fine tuning" the engine. It has a very fine range on the needle valve, to hit the "sweet spot" where it runs at maximum rpm and runs at that rpm consistently without faltering. I have also been playing with the length and strength of the intake valve spring. It is very close now, almost time to add in the link that lets my governor come into play for the hit and miss action. It is running right on the edge of "scary fast".

I've missed a few days and you've been busy  :ThumbsUp: :ThumbsUp: :ThumbsUp:

Looks and runs great Brian, can't wait to see that governor in operation.

Today I am messing around with the hit and miss function of this engine. It definitely works. Engine fires up, gains rpm., up to a point where the governor lever tilts down and the threaded rod blocks the rocker arm from releasing the exhaust valve. Engine goes into miss cycle, and rapidly slows down until rocker arms is released. Exhaust valve is allowed to release, then engine  tries to run again but doesn't quite make it. I have found that my anti-backflow valve isn't working, so while the engine is missing, all the gas in my gas line is running back into the tank. I broke down this morning and ordered  an anti-backflow valve from a hobby shop in Mississauga. It has a neoprene ball in it, which should do a lot better at keeping the gas in the gas line.

Running well Brian

Next engine will have to have a fuel pump on it like the R&V that both myself and Craig have recently done :LittleDevil:

I've only used a NR valve on one engine which was the ball hopper monitor and although I did take the P M Research valve apart can't remember the size of what was inside :headscratch:
