Webster IC Engine build log.
raynerd:
Nick - glad you felt like some time in the shop after seeing the build. I wouldn`t get too excited about the video`s, it only runs for a few seconds and then stops :lol:
I also think that the problem with the engine is the fuel intake. It doesn`t seem to be getting a constant supply of fuel and is only running on a shot of a good rich mixture. The spring is very very light so I really can`t see this is the issue. I`m wondering if the valve seat is a little wide and is causing a larger pressure than ideal to open it? That being said, (very very technical) I can put my tongue on the air intake tube and the suction will pull and lock my tongue to the air intake tube - so it is sucking!
I have made sure the exhaust valve has some clearance but I`ll make a concious effort to make about 0.01" clearance rather than just guessing like I have been doing.
I did remove the check valve some time ago based on one of your earlier post. There is no ball bearing in there so although you see the "check valve" case, there actually is not valve action, it is just a way of attaching the tube to the valve block.
I`ll attempt your other advice as well.
Can you please clarify, what do you mean by:

Try some real gas... way more aromatic, so should provide more bang...

Petrol 87 ?? "Real Gas" ?? Are we talking about unleaded petrol here? I`m sorry, just don`t want to explode anything attempting to run it on what I would consider "gas" ...methane!

excellent! glad to hear that you have some good suction!
Yes, just some gasoline like you put in the car. Exhaust will stink a bit, but it should run pretty strong, I did that early on until I had it broken in and dialed in. That is where you are now.
remember... this is the fun part albeit frustrating sometimes, just listen to the machine and it will tell you all it needs...

NickG:
Nice work Chris, it's so close. Yeah your fuel doesn't seem to be sloshing around like it does on Jan ridders' engines!
klank:
Very well done - I am sure you will get it purring away.
Thanks for such an interesting build.
