Thanks K2 I assembled the crank pieces last night with Loc-Tite and left them to set over night. I then installed tapered pins at all stress points and put it in the engine block. As expected it was a perfect fit but I still had not cut out the main shaft to allow for the rods. Cutting out...

I have been trying to make the original crank work with a center main bearing but every thing I try just makes it worse. Those pieces will go into the "Too good to throw away" bin and I will start over on a new crank shaft. The new crank will not have needle rod bearings as originally designed...

Thanks for the ideas. I will be adding a center crank bearing and closely inspect the entire crankshaft. Ray

The good news first. I made a mount for my distributor and coupled it to the cam via 2 bevel gears. It tracks and turns smoothly. Now the bad news. I was spinning the engine over with my drill and noticed a problem. Around 3000 rpms the flywheel was not tracking straight. When I slowed down...

Yes K2 you get a gold star as the flywheel does turn clockwise. I have never done multi cylinder atmospheric intake valves before is there something about them that I should know?

The intake valves are atmospheric so no cam is needed. They are opened by suction on the intake stroke of each cylinder. Ray

Four brass cam lobes with set screws. I also made up the timing belt tensioner and set the exhaust valve timing. Another view. I have good compression on all four cylinders. Happy Dance Thanks for looking Ray

You are right K2 we just don't know but will find out later. Thanks for the comment they are appreciated. Progress I cutout and polished the cam support blocks and installed the cam bearings. I also roughed out the cam shaft. Then on to the upper cam pulley next. The cam pulley didn't...

Had a little time today so I made some risers to allow for the new flywheel diameter. Thanks for looking Ray

I use a drag knife on a vacuum table to cut my gaskets. I would hate to think what they would look like if I did them with a scissors and knife. Cutting two, one for a spare. I drilled, counter bored and tapped the four spark plug holes in the head. Then I installed the newly cut head...

I believe I have plenty of irregularities in my cylinder liners. :) Thank you sir for the kind words. Ray

Got home yesterday all rested up and ready to go. First item is to make a valve leakage test plate to fit this engine. I can will work on one cylinder at a time lapping the valves until I get good results. Testing Cylinder #3 valves. All four done for now but I won't know just how good...

I made up 10 valves today so I could get 8 that I liked. This is the way I make them. All valves cut to length and threaded. The intake valves are shorter by about 1/4". Why? Because I didn't want to make any more. I have not lapped them in yet but that will have to wait for a few days...

A well thought out and executed idea. Ray

Yes bronze would have been a longer lasting material but I have 14 other model engines that I built with brass guides that are still going strong. Thanks for the comment. Ray
