Hi Post from Master Cam the existing post again and before sent it to mill change the diameter of the existing # tool under description of tool ( make it smaller off .0039'') second line under the first G codes if you have any problems please post a...

I wonder if this link is gonna help. http://www.findsminimodelhotbulbengines.dk/Side1.html They have some nice small injectors

I guess it's never too late to thank you. Three motors are done and i'm working to convert the forth one to diesel. Thanks again Dimitrios

Thanks to everyone who responded and helped me. I started the motor and I am now working on the other three of them.I have to make some changes, and new carbs. The timing AND compression were wrong Thanks again

Hi I am using manual G programing at Mazak M32 control for ID thread with single point treading tool for years without any problem If it is able to use G code programing i can help you if i know the thread / thread pitch, depth and OD of thrading tool

Thanks Ken for the advice If i use the head on photo # 5901 the plug location is over the E side. I change the rotation of the motor from ccw to cw because the fly wheel nut gating loose. On the design the plug is over the intake valve For all the tests i dead to start it I used a cylinder head...

Timing again the motor with a dial indicator and change piston rings wash able to start it for a few seconds This type of cam is a problem to timing because i cut a key on the shaft's taper and the difference in the I and E overlap. Big deference on cylinder compression with new rings without...

Thanks The problem wash the piston compression Deep vertical grooves on cylinder liner I change upper piston ring with mat'l CI and Teflon for the second I must build a new carb and i hope to have better luck this time

Hallow BillC I did all the above to brake in the motor (bushings and piston rings) before i try to start it. This engine is the first one I attempt it to build and i had a few problems with it from the beginning. I downloaded the drawings thru the Internet and started to make the engine parts...

Hi Jim I compressed air through the cylinder head and noticed a little leak from the breather (timing cover). Valves are OK. I must test it again with a pressure gauge. Do you know what numbers I have to look at for the size of the motor? Thanks again

Thanks Mike for the site I think is a nice setup

Yes Admiral_dk the timing is right It pops a lot but can't keep up rpms. It floods, too. With diesel fuel sounds better, more promise

Hello Jim I start it as diesel engine an i realise that the chamber ratio is only 6:1 (should be 20/22:1) I modified two different cylinder head in order to convert it to a petrole engine with a cdi ignition and be able to start it photo#5917 with 1/4-32 spark plug thread on top of cylinder head...

Thanks It is a Whippet 10cc medium-performance liquid cooled petrol engine (spark plug on the side....#10-32 thread)
